NH Plus Series, Three Phase, 20-480 kVA

The Modulon NH Plus series is Delta’s new generation UPS featuring high efficiency, hot-swappable modular structure and N+X redundancy. With its industry leading 94% high efficiency, the NH Plus series delivers remarkably low total cost of ownership in terms of both capital expense and operating expense.

With N+X module and system redundancy to guarantee reliability and availability, the Modulon NH Plus series sets a new milestone for UPS protection in mission critical applications.

  1. Available from 20 to 480 kVA (4 units x 120 kVA in parallel).
  2. Redundancy at module and system level.
  3. Hot-swappable function ensures uninterrupted operations during maintenance.
  4. Redundant auxiliary power and control circuit ensures higher reliability.
  5. Inbuilt maintenance and static bypass switch.
  6. Modular design provides easy maintenance and scalability.
  7. Multi-language LCD display and LED status indicators.
  8. Two smart slots and six programmable dry contact outputs.
  9. Optional external battery cabinet for longer backup time.
  10. Low harmonic distortion (iTHD<3%) optimized generator size to save initial investment.
  11. High input and output power factor (I/P pf >0.99; O/P pf up to 0.9) and 94% high efficiency reduce operating costs.
