9410 Regenerative Grid Simulator

Regenerative Grid Simulator for Testing of Grid-Tied Inverters, V2G, & Other AC Power Products

The 9410 is a four-quadrant (bi-directional) AC/DC source with selectable phase outputs, a built-in waveform-digitizing measurement system and robust line disturbance creation tools. When used in the regenerative (sink) mode, it sends returned power back to the facility mains rather than being dissipated as heat. The most frequent application of the 9410 is use as a grid simulator for testing PV inverters and other grid-tied products for compliance to industry standards.

Advantages & Benefits

Advantages

  • Bi-directional AC – Inverter testing & μgrid simulation
  • More reactive power per kW
  • Simplifies automated test stand development
    – Software selectable 1, 2, or 3 Phase operation
    – Isolated digital inputs & outputs
    – Built-in SW watchdog & safety limits
