The Modulon DPH Series UPS is the ideal modular power protection for MW data centers to achieve total cost of ownership (TCO) optimization..

User-friendly 10" color touch screen; Fully modularized and hot-swappable design


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
Redundancy 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
