ZERO IMPACT SOURCE
MULTI SENTRY UPS are easy to install, especially on sites where there is limited power capacity available, a standby generator and potentially harmonic compatibility issues:
• low input current distortion - less than 3%
• high input power factor 0.99
• power walk-in function to achieve progressive rectifier start-up
• delayed start-up on mains power supply return
MULTI SENTRY also performs the role of a high specification filter, protecting its power supply sources (mains or generator) from any harmonics and reactive power generated by the loads it is powering.
BATTERY CARE SYSTEM
The MULTI SENTRY Battery Care System optimises battery performance, to help extend their working life and ensure that the UPS can deliver its full-rated back-up time when called upon in an emergency.
Battery recharge: MULTI SENTRY is designed to work with VRLA AGM and GEL lead-acid batteries including open-vented types, in addition to Ni-Cads. Specific management features include:
• One-level recharge to meet the requirements of the most common VRLA AGM batteries
• Two voltage level recharge meeting the IU characteristic
• Restricted charging to reduce electrolyte consumption and extend the life of VRLA batteries
Temperature compensation: to avoid excessive voltage being applied to the batteries in a high ambient
Battery test: to detect performance degradation and predict battery failure.
Deep discharge protection: to prevent the batteries being discharged below a level from which they cannot be recovered (especially when discharged over long periods with very low loads).
Low AC ripple current: from a high-frequency battery charger, to ensure the batteries are not subjected to this damaging element commonly experienced with some other UPS and power supply designs.
Wide input voltage range: from a rectifier that can work down to less than 40% of its nominal supply rating (at half load), removing the need to discharge the batteries.
FLEXIBILITY
MULTI SENTRY can be used for a wide range of applications, thanks to its configuration options, flexibility, accessories and performance levels:
• suitable for powering capacitive loads, for example Blade servers - without any reduction in active power, from 0.9 leading to 0.9 lagging
• modes of operation include: On-Line, Eco, Smart-Active and Stand-By/Off
• frequency conversion mode
• Power Share connections for priority-based load shedding when the mains power supply has failed
• cold-start facility to switch the UPS on even without a mains power supply present
• extensive back-up time options using battery extension cabinets
• optional battery cabinet temperature sensor to assist the temperature compensating charger
• optional battery chargers to optimize recharge times
• optional dual input supplies
• optional isolation transformers for Galvanic isolation and neutral connectivity

Further advantages
- The Multi Guard UPS power modules use the latest DSP microchip technology. This reduces hardware components, increases UPS reliability and also makes it easier to update and maintain the software.
- The UPS operates with load sharing technology. Should any of the UPS modules fail, the load will be taken over by the rest of the modules without interruption. This increases the real time operation and power availability compared to other standby UPS.
- The Multi Guard UPS is designed to connect to external battery banks in order to ensure the required battery run time.
Advanced Modular Design
The Multi Guard system contains UPS modules, a LCD Display module, the PDU and other accessories. Each UPS module is a fully independent 15kVA UPS. Thanks to the advanced wireless parallel control technology and smart communication, the UPS modules and LCD display modules can be easily replaced at any time without affecting UPS operation. The user friendly “plug & play” design simplifies UPS servicing and maintenance.
The Multi Guard de-centralises the control units in each UPS Module. The LCD Display module is for display and communication purposes only. If the LCD Display module fails, the UPS system still functions and supports the load without any interruption.
High capacity MTBF
System MTBF for two modules in parallel is more than 1,000,000 hours and power availability is above 99.999%. Each 15-120 kVA redundant configuration guarantees correct operation even in the event of the failure of one of the UPS modules. The module replacement procedure only takes 5 minutes for full system recovery.
This solution allows you to:
• Minimise downtime;
• Reduce the number of stored spare parts;
• Avoid the need for specialised technicians
Intelligent recharging system
The Multi Guard UPS system applies a two step intelligent charging system. The first stage is a constant charging current that can recharge the battery capacity to 90% very quickly. The system then transfers to a constant voltage mode to guarantee the battery can stay fully charged all the time.
This intelligent charging system not only reduces the battery recharging time but also extends battery life, saving on battery replacement costs.
Modular Autonomy
The Multi Guard 30 and 60 versions are designed to build up internal run time using a single battery module for all power and autonomy requirements.
The same battery module is also used to build up the required autonomy in an external cabinet.
Low total Cost of Ownership (TCO):
− Lower system set-up costs
− Lower energy costs
− Lower cooling costs
− Lower expansion costs
− Lower maintenance costs.
UPS power selection
The Multi Guard can be configured from 1 up to 8 modules in its cabinet to form the most suitable N + X configuration for the application.
Multi Guard grows as your needs grow by simply adding further UPS modules and battery modules to the existing frame. The initial investment is recuperated in cost savings. New power supply requirements can be satisfied without complex and costly replacement operations.
Multi Guard Industrial
Power Range: 160 kVA
1-3:1 1-3:3
Modularity and strength
High adaptability to input voltage
Multi Guard Industrial is available in two versions: single-phase and three-phase output, whilst the input stage accepts both a triplet of three-phase supplies out-ofphase by 120° (three-phase 400 V+N) or a triplet of power supplies in phase (singlephase 230 V+N). Thanks to its power supply recognition function the UPS is able to adapt to the input power supply with no need for additional configuration, ensuring the same performance under both applied voltage conditions.
Zero impact source
Thanks to the technology it employs, Multi Guard Industrial solves all problems connected with insertion into power supply grids with limited power, where the UPS is supplied by a generator and where the same network includes single-phase (e.g. railway voltage) and three-phase (e.g. emergency power supply from a generator) supplies. Multi Guard Industrial has zero impact on the power supply source, whether it is a mains grid or generator set, single-phase or three-phase:
- power supply voltage recognition (single/three-phase), with no need for setting up or reconfiguring parameters
- input current distortion < 3%
- input power factor 0.99
- power walk-in function that ensures progressive rectifier start up
- start-up delay function, to restart the rectifiers when mains power is restored if there are several UPS in the system.
- "cold start" function for starting the UPS from the battery.
In addition, Multi Guard Industrial plays a filtering and power factor correction role in the power network upstream of the UPS as it eliminates harmonic components and reactive power generated by utility suppliers.
Compatible with industrial environments
The mechanical structure of Multi Guard Industrial makes it particularly versatile for
use in many different sectors.
The basic building blocks are 20 kVA UPS. The cabinet is able to house up to four 20 kVA modules and up to two cabinets can be connected in parallel for a total of eight UPS modules and 160 kVA of power. The module connection clamps are laid out so that the communication signal connections are segregated and separated from the power connections (input, output, by‑pass line, battery), thus ensuring complete immunity from interference
generated by the power supply grid, which is typically disturbed in industrial environments.
Both versions (single-phase and threephase output) are provided with a by‑pass line separated from the power supply line. This ensures greater availability in that the customer may have a preferential line for the by‑pass that is not restricted by the potential interference or interruptions that the UPS power supply line may be subject to.
The UPS module has a front to back air flow, allowing the UPS to be installed in any environment and preventing the types of ingress problems associated with topvented circulations cabinets.
Every UPS module in the Multi Guard Industrial range can be equipped with a parallel board, a relay board with eight programmable outputs and three inputs (one of which is programmable), and two slots for housing communications interface boards from the MultiCOM range, making the UPS compatible with the various types of protocols and supervision systems typical of the industrial environment. The cabinet is designed to house up to four UPS modules. I t has an area that contains all the protection devices and disconnectors for the individual modules (4 input disconnectors, 4 battery disconnectors, 4 bypass line disconnectors and 4 output disconnectors), as well as a manual bypass for isolating the four modules and guaranteeing power continuity in the event of the complete failure of all the UPS units or in the event of scheduled system overhaul.
The cabinet is also equipped with an area that can be used for the insertion of a whole range of accessories for monitoring power that the user can request (surge arresters, energy meters, earth discharge detectors, output distribution, release coils, etc), making the solution compact and optimised for any field of use.
Modular Plug & Play solution
Multi Guard Industrial can be purchased as a single 20 kVA UPS module and installed in any cabinet or mechanical support provided by the user. The power terminals (input, output, battery) are connected by Harting connectors, ensuring simplicity and operating safety during insertion/removal, protection against electrical contacts and immunity from environmental conditions typical of industrial environments (dust, humidity, suspended chemical particles).
The removal and replacement of a faulty module or the addition into the system of a further UPS module to increase available power or redundancy can be carried out easily by the operator responsible for the system.
Complete flexibility
Multi Guard Industrial is the ideal solution for industrial environments in which the UPS must adapt to the various requirements typical of this application. Aside from the distinction between single-phase and threephase output voltages, the UPS module can be used as a stand-alone unit or in a parallel configuration; by simply adding the parallel configuration board in the slot on the front of the module, the UPS can grow as requirements demand (from 20 to 160 kVA).

Maximum protection and performance
The MASTER MPS range has been enhanced with the HP series available from 100 to 600kVA
MASTER HP Series provides maximum protection and power quality for data centres and industrial loads. The UPS has an IGBT-based rectifier, DSP (Digital Signal Processor) technology and provides true On-line, double conversion power protection, (VFI SS 11 - Voltage and Frequency Independent in accordance with IEC EN 62040-3).
The HP series provides exceptional operating efficiency (over more conventional thyristor rectifier-based systems), a compact footprint and easy maintenance access - all ideal for today’s critical operating environments.
ZERO IMPACT SOURCE
As an evolution of the MASTER series, the HP features the added advantages offered by an IGBT-based rectifier assembly. This further reduces the impact of the UPS on the local supply and simplifies installation where there is limited power capacity in the form of available electrical supply rating or generator size.
The MASTER HP is classed as a ‘Zero Impact Source’ and provides:
• Low input current distortion – less than 2.5%
• High input power factor 0.99
• Power walk-in function that ensures progressive rectifier start up
• Delayed start up phased with the return of mains power supply, when several UPS are connected in the system.
MASTER HP also performs the role of a high performance filter, protecting its upstream power supply sources from any harmonics and reactive power generated by the loads powered.
BATTERY CARE SYSTEM: MAXIMUM BATTERY CARE
MASTER HP uses the Battery Care System, also available on the MASTER MPS models, which optimises battery performance in order to extend the battery life for as long as possible.
FLEXIBILITY
The configuration with the output transformer, a feature of both the MASTER HP and conventional series, is characterized by the galvanic isolation of the load and the battery for greater versatility in system configurations.
As a matter of fact it allows for two network inputs (main and emergency) separate, and coming from two different power sources; this is particularly suited to parallel systems in order to ensure the selectivity between the two sources, thus improving the reliability of the entire installation.
Main features
• High output power
• Compact size: only 0.85 m2 a for 250kVA UPS
• Reduced weight
• Double load protection, both electronic and galvanic, for the battery.
The MASTER HP range is suitable for use in the widest selection of application. Thanks to the flexible configurations, accessories and options available, it is suitable for powering capacitive loads, such as blade servers.
Reliability and availability of the power supply for critical applications is guaranteed by the distributed or centralized parallel of up to 8 units for (N+1) backup or power parallel, and by all the various configurations available in the MASTER MPS range.
