    Delta extends Ultron DPS series UPS as a highly efficient backup power for green datacenters and other mission critical operations

    Delta Electronics, the world-leading energy-saving solutions provider, today launched its Ultron DPS 500kVA uninterruptible power supply (UPS) in China, Taiwan, EMEA, Russia, India and South America. The Ultron DPS 500kVA extends the existing line of 60-400kVA models, strengthening Delta’s position as a provider of high performance and high efficiency UPSs.

    “Witnessing the global trend of datacenter consolidation and scale up, we are rolling out our DPS 500kVA model, which can be paralleled up to 8 units (4MVA in total) for power expansion or N+X redundancy, to meet the growing power demand of large and extra-large datacenters.” said Mr. Dennis Lin, Chief Engineering Officer of Delta Mission Critical Infrastructure Solutions (MCIS) Business Unit. In addition to its large power capacity, the DPS series also features high AC-AC efficiency of up to 96% at 50% load and above as datacenter customers are becoming more eco-conscious. Even at light loads of 20-30%, which is the typical datacenter load, the efficiency can be 92-93%, saving significant operating costs.

    Since the DPS UPS series was introduced to the global marketplace in 2012, it has received much recognition and praise by customers from various fields. With the roll out of the 500kVA model, the Ultron DPS series now ranges from 60kVA to 500kVA and can be applied to multiple vertical markets. Besides computing services and datacenters, the DPS series has also found application in the power protection of mission critical equipment in industries such as healthcare, infrastructure, telecommunication, manufacturing, banking and finance, and more.

    To meet the “green” requirements of customers, the Ultron DPS is designed with three level IGBT topology for both power factor correction (PFC) and inverter to achieve industry leading performance of up to 96% AC-AC efficiency. In addition, thanks to Delta’s advanced digital PFC control, it also offers a low iTHD < 3% and high input power factor > 0.99. “Delta’s Ultron DPS series continues to offer customers the benefits of superior power protection, high energy efficiency, and best-in-class TCO savings,” said Dennis Lin.
