UPS system provides ease of deployment in large data centres

UPS system provides ease of deployment in large data centres
A 400kVA UPS system, designed to meet the needs of 575-600V applications, has been released by Emerson Network Power. For data centres that need to quickly scale to meet spiking power demands, the Liebert NXL enables a faster, easier and more cost-effective deployment by using optimised internal transformers. This eliminates the need to install and wire separate external input and output transformers.

Power converters deliver leading efficiency & form factor

Power converters deliver leading efficiency & form factor
Murata has announced the launch of the D1U86P series of ultra-high density power converters. Each power supply generates a main output of 12VDC with a 12VDC standby output for power management circuitry. The main DC output delivers up to 133.3A, with droop current sharing when parallelling multiple power supplies. Up to eight power supplies may be used in parallel for very high current applications.
