DPS Series, Three Phase, from 160 to 500 kVA, scalable up to 4000kVA in parallel

Leading in power performance and efficiency

Delta’s Ultron DPS is a double-conversion and IGBT-rectifier three phase UPS. With the three level IGBT topology for both PFC (power factor correction) and inverter, the Ultron DPS features industry leading performance of up to 96% AC-AC efficiency. Thanks to Delta’s advanced digital PFC control, it also has low iTHD < 3% and high input power factor > 0.99 resulting in significant total cost of ownership (TCO) savings. Aiming to achieve the highest availability possible, Delta has enhanced special designs for battery management, hot-swappable fans and ease of maintenance.

The excellent power performance and high system availability of the Ultron DPS provide customers with the benefits of a stable power supply, high power efficiency, low capital investment and low overall operation cost.

Features

High Reliability

N+X redundancy or hot-standby configuration increases system reliability

Wide input voltage range (DPS 160~500kVA : -40% ~ +20%) allows the UPS to work in harsh electrical environments

Field programmable sequential start-up reduces the impact on the generator

Intelligent fan speed control and redundant fan design prevent UPS from overheating and increase system reliability

N+X redundancy or hot-standby configuration increases system reliability

 

Reduced Total Cost of Ownership

High AC-AC efficiency even at light load levels reduces energy loss and saves operating costs

High input power factor (> 0.99) and low input harmonic distortion (iTHD < 3%) eliminate the need to over

High AC-AC efficiency even at light load levels reduces energy loss and saves operating costs

 

High Flexibility

Delta Ultron DPS series UPS are available in full power ratings ranging from 160kVA to 500kVA in a single unit to fit each specific application requirement.

There are three different cabinets of Ultron DPS series UPS with optimized footprint. Customers can save valuable space from the leading power density and compact design. Light weight also reduces transportation and installation costs.

Parallel expansion of Ultron DPS series UPS up to 4000kVA without extra hardware allows quick capacity upgrade to meet business growth.

Parallel expansion of Ultron DPS series UPS up to 3200kVA

Common batttery configuration of Ultron DPS in parallel mode can support customers to:

Significantly save installation space and rent expenses

Reduce additional investment on batteries

Make UPS expansions easier without addi tional battery investment

Save the costs of possible floor loading enhancement

Common batttery configuration of Ultron DPS in parallel mode can support customers

Easy Maintenance

Hot-swappable fans reduce maintenance lead time (applicable for models 160~500kVA)

Built-in manual bypass allows “zero downtime” to ensure system availability during service maintenance

Main I/P and O/P switches detection provide quick diagnosis when faults occur

Hot-swappable Fan

 

Intelligent Battery Management

Delta intelligent battery management system can sustain battery lifespan and the capacity of battery backed up through the functions of :

Battery temperature monitoring & compensation

Battery remaining capacity displayed in percentage

Over charge/discharge protection

Boost/float stage charge

Auto/manual battery test

38~42 battery units in one battery cabinet optimizes investment (applicable for models 160~500kVA)
