Energy-Saving Three Phase Utility Grid Simulator

July 13, 2015

The PAS-F Series is a new programmable three-phase utility grid simulator that conserves energy and doesn't require a parallel load. It combines utility grid simulation and regenerative bi-directional AC source that is capable of both sourcing and sinking the full current load from the device under test (DUT). With power levels ranging from 45 kVA to 1.6 MVA, the series is capable of testing the largest of dispersed energy inverters.

When testing dispersed energy products such as PV inverters, energy storage systems and wind turbines, the traditional test set up requires a load bank in parallel with the DUT and AC source. The PAS-F does not require the parallel load. Instead full DUT current is sunk into the AC source and 92% of the power is regenerated back to the utility grid, saving energy and reducing system cooling requirements.
