Active Power Inc. has been selected by a utility company for four of its high efficiency CleanSource 1000 kVA UPS (uninterruptible power supply) systems. The utility deployed the critical backup power equipment at its datacenter facility in North America late last year to provide both power conditioning and protection to the mission critical site. The customer set out to bring online one of the most energy efficient, highly resilient, and environmentally conscious data processing facilities in the industry. To accomplish this, the customer chose a 415 volt/240 volt power design instead of the North America standard 480 volt. This design approach eliminates voltage transformation at the power distribution unit level and the need for additional transformation equipment, resulting in significant improvements to overall datacenter energy efficiency. To help meet design requirements, Active Power configured its CleanSource UPS to 415 volt and secured Underwriter Laboratories (UL) certification on the system. The system also underwent a shaker table test to meet stringent seismic code requirements due to the location of the datacenter.
