SIEL Energy systems have successfully completed 3 new major UPS replacement installations for a major international IT services provider. SIEL Energy Systems were selected to supply, install and commission the highly acclaimed modular UPS5000-S UPS system This market-leading product provides unparalleled system flexibility and efficiency. The 3 installations provide a combined total capacity of 5.2MW to provide an uninterruptible power supply to the client’s critical data centre load.
All 3 installations are composed of the UPS5000-S modular system. These units are rated at unity pf so in the case of the 400kVA frame, can provide a full 400kW output. ‘Capacitive’ or ‘Inductive’ loads having power factors of anywhere between 0.5 lead to 0.5 lag can be supported without further de-rating. In addition to the high power output, the UPS5000-S achieves a remarkable level of efficiency. At 40% load in double on line conversion mode, an efficiency of >97% is achieved. This provides long-term cost savings over the equipment lifetime both in UPS operating costs and ancillary equipment costs, such as cooling, due to the reduced heat output of the UPS modules whilst the reduced cabinet footprint of only 1.2M2 frees up valuable floor space.
