Bidirectional DC Power Supply

Bidirectional DC power supplies both source and sink DC power from a single unit, feeding absorbed energy back to the grid rather than dissipating it as heat. This makes them the preferred choice wherever a test involves genuine charge/discharge cycling — battery cycle-life testing, regenerative braking simulation, and any application where the same instrument needs to both power a device under test and absorb energy coming back from it.

All three ActionPower platforms below deliver true two-quadrant operation with sub-millisecond to low-millisecond response: CORTEX for laboratory and production-scale test, TITAN and NEXUS for megawatt-class EV battery pack and grid-scale energy storage validation.
