Preen ADC Series

Not every DC power application needs the programmability and disturbance-simulation features of Preen's higher-end ADG platform — production line power, burn-in testing, and integration into larger systems often call for a straightforward, cost-effective DC supply where price per kilowatt matters more than advanced programmable functions. Preen's ADC series is built for exactly this segment: a classic rack-mount DC power supply optimised for cost efficiency at scale.

Power density is a genuine strength here — the 2kW and 4kW models fit in just 2U of rack space, and the 8kW model in only 4U, meaning a rack of ADC units delivers considerably more power per rack unit than bulkier alternatives, a real consideration where equipment room or production line floor space is at a premium. Output voltage spans 0-30V through 0-600V depending on model, with both constant-voltage and constant-current operating modes covering the majority of standard DC power requirements without needing programmable waveform or disturbance simulation capability.

Units parallel up to a combined 24-64kW using standard 19-inch cabinets (18U, 32U, or 42U depending on target power), letting a production or test setup scale total available power simply by adding units to an existing rack rather than replacing equipment. Remote sense compensates for voltage drop across long cable runs to the load, maintaining accurate regulation at the actual point of use rather than just at the supply's output terminals.
