Programmable AC Power Sources: Simulate AC mains and line fault conditions

Programmable AC Power Sources and Regenerative Grid Simulators with a wide range of voltage, current, and power for simulating AC mains and line fault conditions. Choose from single and three phase output AC power sources with power levels range from 500VA to 630kVA for design validation, production, and education either in the lab or in automated testing applications. Built in 16-bit measurement circuit and firmware utilities to measure true RMS voltage, current, true power, VA (apparent power), VAR (reactive power), power factor, current crest factor, peak repetitive current and inrush current.

We know you have a choice when selecting an AC Power Source, but the advantage is clear with Chroma. We invest more in R&D than any other manufacturer, so you can be sure you are getting the most out of your lab’s equipment budget.

Advantages include:

  • Programmable voltage and current limit
  • Programmable slew rate for changing voltage and frequency
  • LIST, PULSE, STEP mode functions for testing Power Line Disturbance (PLD) simulation
  • Voltage dips, short interruption and voltage variation simulation
  • Harmonics, inter-harmonics waveform synthesizer
  • Remote interfaces: GPIB, RS-232, USB and Ethernet
All of our AC Power Supplies are designed to satisfy both automated test system and laboratory benchtop requirements.
