DPH Series 25-75/150/200 kW

The modular UPS ideal for medium-sized datacenters

Introducing the next generation of modular uninterruptible power supply (UPS) systems designed for ultimate availability, excellent performance, high efficiency, and ideally suited for medium-sized datacenters.The Modulon DPH Series UPS is a modular UPS used extensively for critical operations, since it provides 25% more power output compared to power factor 0.8 UPS systems. Designed for the most stringent datacenter requirements, the Modulon DPH Series offers the highest possible availability. With its modular structure, the true on-line, double conversion, three-phase Modulon DPH Series UPS system offers a scalable architecture for optimal power designs. It provides 25kW to 200kW of uninterruptible power with additional 800kW capacity in parallel.

The Modulon DPH Series’ scalable architecture is available in a 19″ enclosure, and supports vertical and horizontal expansion for versatile installation arrangements. Integration of your power distribution can take shape within the same rack or in parallel rack enclosures. Optimal placement is ultimately decided by the needs of the datacenter, not the limitations of the UPS system.

Built-in redundancy guarantees a continued power supply for mission critical applications, and the fully fault-tolerant design of the Modulon DPH Series offers self-redundancy for the control mechanism, cooling and power modules. Mean time to repair (MTTR) is close to zero, due to hot-swappable functionality for all critical components. In the event of failure by the main module, full control logic enables the system to self-synchronize and switch to the backup, for a seamless transition with no disruption to operations.

Delta’s Modulon DPH Series UPS provides one of the highest efficiency ratings in its class. With fully rated power, this modular 3 phase UPS delivers maximum power capacity, better power protection and quality to the load. Scalability, availability, and efficiency distinguish the Modulon DPH Series UPS as the best solution for power protection and distribution in your datacenters.

Delta- DPH Series Applications


Ultimate Availability

  • Advanced fault-tolerant design achieved by self redundancy to guarantee operation continuity
  • Self-synchronization of power and control modules for continuous on-line operation even in the event of control module failure to avoid downtime caused by single point failure
  • Hot-swappable key modules and components to ensure Mean Time To Repair (MTTR) close to zero without downtime risk
  • Wide input voltage range of -45% to +25% and narrow output voltage regulation window to cope with harsh utility conditions and seamlessly provide stable power supply to the load
  • High overload protection to support 125% overload for 10 minutes and 150% for 1 minute

High Scalability

  • Vertical expansion from 25kW to 75/150/200kW supporting N+X redundancy in a single rack enclosure to save footprint
  • Parallel expansion up to four units without requiring additional hardware
  • Variable configurations possible providing the scalable flexibility up to Tier 4 standard
  • Excellent Power Performance and Efficiency
  • Fully rated power (kVA=kW) to maximize power availability
  • High AC-AC operating efficiency of 95% at 30% light load and 96% from 50% load resulting in marked energy cost savings
  • Low harmonic pollution (iTHD<3%) to reduce upstream investment costs and meet demanding power requirements

Easy Maintenance

  • Built-in manual bypass features to eliminate maintenance-related downtime
  • Proactive detection of fan failure and switch fault for early diagnosis on UPS malfunction
  • Plug and play to simplify the maintenance process

Management System

User-friendly Control InterfaceDesigned for management ease, the Modulon DPH is fully equipped with user-friendly monitoring and controls in various languages. A big graphic LCD screen provides the needed control for all communication and command options at the tip of your fingers to monitor and control functions on a single page view. Direct event log viewing helps quickly diagnose events without additional hardware requirements. Up to 3,000 event logs can be recorded.

Integrated Monitoring and ManagementDelta UPSentry 2012 communicates with UPS through physical interface RS232 and USB for UPS manageability. Also works with Shutdown Agent 2012 to protect a group of PCs, workstations, or servers. Delta New Shutdown Agent cooperates with SNMP card or UPSentry 2012 to shut down multi-servers in various operating system and virtual machine gracefully to prevent possible data corruption. Furthermore, Modulon DPH can be monitored and controlled together with other datacenter equipment by Delta InfraSuite Manager (EMS 3000) as a total datacenter control and monitoring solution.
