DPH series 50-500kVA UPS - Applications


Excellent Power Performance

  • The industry’s leading power density per module at 50kW in 3U space, and the smallest footprint for 500kVA in a single rack and 600kVA in two racks, to achieve the best utilization compared with its peers
  • High AC-AC efficiency up to 96.5% and ECO mode to 99% resulting in marked energy cost savings
  • Green mode featuring a load aggregation function optimizes system efficiency

Ultimate Availability

  • Fully modularized design and hot-swappable key modules ensure Mean Time To Repair (MTTR) close to zero without downtime risk
  • Redundant components and dual CAN bus delivers highest system availability and avoids single point of failure
  • Modular UPS grows with your business by parallel expansion up to 8 units for 4.8MVA of total power capacity

High Manageability

  • User-friendly 10” color touch screen enables easy local UPS management
  • Environment information such as security, water, fire, and temperature can be integrated into the UPS for easy monitoring via the LCD of the UPS
  • If the UPS is equipped with an external battery management system, the battery information can be integrated into the UPS and monitored via the LCD of the UPS
