Nuclear Digital ProcessPower® UPS

Single Phase: 5 - 50 kVA

The Nuclear Digital ProcessPower® (NDPP) Uninterruptible Power Supply system from AMETEK Solidstate Controls is a true on-line, double conversion UPS system that provides continuous, clean, regulated power for nuclear class 1E safety related applications. This unit is a single-phase, 5-50 kVA, though additional sizes are available.

This UPS is designed specifically for process control and industrial application, with 40-year qualified design life. The 1E qualified NDPP has been developed and tested within a NRC inspected 10 CFR 50 Appendix B Digital Quality Assurance program, which Solidstate Controls has built. Enhanced safety features include user-interface, seismic bracing and employment of electromagnetic interference (EMI) suppression. The NDPP system incorporates an IGBT bridge and feedback-controlled Pulse-Width-Modulation (PWM) technology to reduce the footprint and provide tighter output regulation.

The NDPP is as reliable as the Digital ProcessPower systems, but incorporates additional safety measures for software integrity and cyber security. The software features diagnostics, self-checking, system monitoring, data capturing and event logging capability without the need for external communication with other plan safety systems.
