Unidirectional DC Power Supply

Unidirectional DC power supplies source DC power only — no regeneration or sink capability — making them the simpler, more cost-effective choice for the majority of lab bench, production-line, and burn-in applications where a device under test only needs power delivered to it. They're used across component and sub-assembly test, EV motor and PV inverter input simulation, battery charging, and general R&D bench work wherever a stable, adjustable DC source is needed in place of a fixed supply.

Below, Preen's ADC and ADG-L lines cover rack-mount production and general-purpose bench needs, while ActionPower's ZETA and CORTEX platforms target ultra-precision laboratory and high-power production test respectively.
