Multi Guard (120 kVA)

Multi Guard (120 kVA)

On Line UPS

The Multi Guard modular UPS is a scalable three-phase / three-phase uninterruptible power supply system with double conversion technology. Its power capacity ranges from 15KVA to 120KVA, delivering the best combination of reliability, functionality and flexibility. The Multi Guard N+X parallel architecture adopts a highly intelligent modular design to achieve maximum power availability and redundancy. It is specially designed to meet the protection demands of mission critical loads in data centres or other important applications.
Each module has an individual power capacity of 15 KVA, and a standard cabinet can be fitted with up to 8 modules to reach 120 KVA. If the load is within permitted limits, modules can be hot-swapped to enable true power continuity without any interruptions.

System features

  • Maximum 120KVA capacity in a 19″ rack.
  • Input power factor >0,99 THDi <2% and output voltage distortion equal to 1,5%.
  • 15 KVA per module with hot-swap function.
  • The LCD display on the front panel displays unit status and important information such as input and output nominal values, capacity, temperature and autonomy.
  • Communication port for standard Ethernet and relay contact board.
  • DSP technology, IGBT input.
  • 36 Ampere battery charge current on a 120 KVA system.

Advantage
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.

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 30
Multi Guard 30 is the entry level to the range. It is the ideal solution for supplying medium-power loads that require one level of redundancy.
The solution is very compact and allows the possibility to expand autonomy up to one and a half hours for a 15 KVA model in a N+1 configuration.

MULTI GUARD 60
The Multi Guard 60 system allows you to install from one to four UPS modules (15 KVA to 60 KVA) in a 19″ rack cabinet, which is able to house up to 5 battery shelves.
If redundancy is required (N+1 modules) the max. output power will be 45 KVA.

MULTI GUARD 120 
The Multi Guard 120 system allows you to install from one to eight UPS modules (15 KVA to 120 KVA) in a 19″ rack cabinet, with batteries housed in an external cabinet. This cabinet houses the same battery modules as those used for the GMT 30/60 versions, up to a maximum of 9 battery shelves.
