The PowerWave 9250DPA UPS is said to have the lowest cost of ownership in its class and deliver energy efficiency in true online mode across a wide range of loads Kohler Uninterruptible Power says that, thanks to three-level interleaved technology, the UPS achieves an efficiency of more than 97 per cent in a wide operating range when the load is between 25 and 75 per cent.
The company says that with Xtra VFI mode, the UPS automatically adjusts the number of active modules according to load requirements.
Modules not needed are switched to standby and activate if the load increases or the mains fails.
Up to six 250kW frames and up to 30 modules can be paralleled for 1.5MW of power.
And it says that ring-bus communication ensures there is no single point of failure.
Kohler says that Decentralised Parallel Architecture (DPA) means each UPS module contains the hardware and software required for full system operation.
They share no common components leading to high availability.
Maintenance is said to be fast and secure – it can take as little as 10 minutes to extract a module, replace a consumable part and be back online.
There is a graphical display to view system status, commands and measurements.
