Intepro Systems announced the introduction of the PAS-F Series of programmable three-phase utility grid simulators. The PAS-F system 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 45kVA to 1.6MVA, 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 system 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.
