Modular UPS - DPH Series

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.

Ultimate Availability for Mission Critical Operations
The Modulon DPH supports ultimate availability to ensure the continuity of mission critical operations.

The datacenter constitutes the critical load in the daily operations of the organization. Cost of downtime due to critical load failure is extreme and runs between USD4,000 to USD6,000 per minute or even more. To achieve the highest availability possible for the datacenter, it is vital for the most reliable products or solutions supported by the shortest or even zero Mean Time To Repair (MTTR).

The fully fault-tolerant design provides self redundancy to the control mechanism, cooling and power modules. Full control logic allows the system to self-synchronize in the event of main module failure and automatically switch to the backup for assured continuous operation.

Furthering the advantages, the hot-swappable functionality of critical components and modules improve the serviceability of the UPS system thereby reducing MTTR close to zero to assure maximum uptime and ultimate availability in the datacenters.

As illustrated, the Modulon DPH can run under inverter mode and bypass mode to sustain uninterruptible power supply to critical load:

In the event of STS module removal, the Modulon DPH still functions under inverter mode (normal mode without bypass utility backup). During failure in normal mode, such as over temperature, overload, short circuit, abnormal output voltage, or low battery, the Modulon DPH smoothly transfers over to bypass mode.

In addition, the Modulon DPH has a wide input voltage range of -45% to +25% and narrow output voltage regulation window to cope with harsh utility conditions, seamlessly providing stable power supply to the load. In the event of overload, the Modulon DPH supports 125% overload protection for up to ten minutes and one minute at 150%.

The Modulon DPH assures exceptional reliability and maximizes uptime to deliver six-nines availability contributing to the best-in-class practice to reduce Total Cost of Ownership (TCO).

Modularity Designed for Scalability
Scalable architecture allows you to optimize cost expenditure to meet your power demands and deliver uninterrupted services in line with the business growth without over-sizing the power capacity.

The plug and play design of power module supports vertical and horizontal expansion of power capacity at the right time with the right investment. In the situation of a single rack enclosure, the system can vertically scale from 25kW to 75/150/200kW and achieve N+1 or N+X redundancy in the same rack. As business demands grow, the flexibility of the Modulon DPH allows for parallel expansion of up to four units without requiring additional hardware.

The Modulon DPH offers the advantages you need without the high initial investment costs or sacrificing power capacity so as not to create investment excess due to capital waste.

Excellent Power Efficiency and Performance

Excellent power performance and efficiency directly translate into significant reduction of operational costs.

Two key trends have developed in the world of datacenter operations – demand for power and the cost of that power. Today’s management is facing growing pressure to optimize performance for sustainability and growth.

Delta’s UPS solutions deliver one of the highest power performance and efficiency ratings available while reducing cost. The Modulon DPH delivers fully rated power (power factor=1, kVA=kW) providing the maximum power capacity to the load. Compared to UPS systems with output of PF=0.8 and PF=0.9, the DPH supplies 25% and 11% more power, respectively. Other than that, the fully rated power factor is supported by a “stronger” inverter design providing better power protection and quality to loads.

The Modulon DPH demonstrates excellent power performance with low total input harmonic distortion (iTHD<3%). Its reduced load pollution increases power quality, optimizes generator sizing to increase your investment savings, reduces installation costs, and extends the life of valuable equipment.

The Modulon DPH features excellent AC-AC efficiency up to 96% at half load and places itself among the highest in its class. In addition to energy saving, higher efficiency levels also mean less heat dissipation, giving way to lower cooling costs.

Excellent power performance and efficiency lower operation costs significantly. The Modulon DPH combines these benefits to provide high performance, efficient power protection to maximize operational savings for any datacenter.

Easy Maintenance
Hot plug and hot swap simplify the maintenance process.

The Modulon DPH hot plug and hot swap architecture makes best use of a modularity design for 50% faster time of repair compared to traditional UPS systems. Plug and play modularity also eliminates the risk of second fault occurrence caused by complex failure checking and removing processes. The reliability of maintenance and service is guaranteed, further assuring the system availability.
