Delta Ultron DPS

In a highly competitive market where UPS performance and reliability are required, keeping pace is simply not enough. To fulfill your current and future needs, choosing Delta’s Ultron DPS series is a solution worth considering. It is best suited for applications requiring power ratings of 60kVA to 500kVA.

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, swappable fans and ease of maintenance.

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. To increase system reliability in the challenging electrical environments common for today’s businesses, Delta has designed the Ultron DPS with an input voltage range -40% ~ +20%, for clients looking to build a foundation on a N+X redundancy / hot-standby configuration. Intelligent fan speed control and redundant fan design that prevents overheating is also featured in the Ultron DPS.

With its state-of-art design, intelligent fan speed control and redundant fan design, Delta’s Ultron DPS UPS series provides a cornerstone for power performance and efficiency.


  • N+X redundancy or hot-standby configuration ensures increased system reliability
  • Wide input voltage ranges allows the UPS to work at optimal performance levels even 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 overall system reliability
  • Parallel link functionality improves the stability of the output load, keeping the output load stable and the flow of power uninterrupted in the event of failure by a single UPS
  • High AC-AC efficiency even at light load levels reduces energy loss and lowers ongoing operating costs
  • High input power factor (> 0.99) and low input harmonic distortion (iTHD < 3%) eliminate the need to oversize the genset, reducing initial capital investment
  • Hot-swappable fans reduce maintenance lead time (applicable for 160 kVA UPS through 500 kVA UPS models)
  • Built-in manual bypass allows zero downtime and ensures system availability even during service maintenance
  • Main I/P and O/P switches detection provide quick diagnosis when faults occur
