Chroma AC Power Sources

Chroma designs and manufactures five families of leading edge programmable AC power sources, precision power supplies, frequency converters and related instrumentation for simulating AC mains and line fault conditions. Our AC Power Sources are used in automatic testing equipment and bench top applications including avionics testing, IEC testing, Mil-std-704 Avionics, DO-160 Shipboard testing and power supply test applications.

Regenerative Grid Simulator: 61800

Designed for PV inverter, Smart Grid and EV related test applications, the 61800 Regenerative Grid Simulator is a full 4 quadrant, fully regenerative, programmable AC power source with advanced features for compliance, safety and product verification testing.  Power can both sink and source from the UUT seamlessly to support a multitude of applications. In cases where the UUT sources current, a detection circuit will sense the excess power and recycle it back to the grid. Using state-of-the-art digital control technology the 61800 can deliver up to 300VAC at output frequencies ranging from 30Hz to 100Hz. The AC+DC feature allows for applications that require a DC offset bias.

Power rating: 30kVA / 45kVA / 60kVA single or three phase output
Output voltage: 0-300VLN / 0-520VLL
Unique Features

  • Full 4 quadrant, fully regenerative up to 100% of output current rating
  • Programmable voltage and current limits
  • Voltage dips, short interruption, voltage variation, phase angle control, etc.
  • Harmonics, inter-harmonics waveform synthesizer
  • GPIB, RS-232, USB and Ethernet
