Keysight basic DC power supplies offer essential features for a tight budget. The Keysight N8731A is a 8V, 400A, 3200W, single output power supply in a small 2U package. It offers flexible AC input options, analog/resistance control of output voltage and current, as well as parallel and series connection of multiple supplies to achieve more output current or voltage respectively.

Please select the AC input voltage option carefully. The AC input voltage hardware is permanently installed at the factory and cannot be changed under any circumstances after delivery.

If the wrong AC input voltage option is purchased and delivered, the unit would need to be returned. Product returns are subject to Keysight approval and applicable charges. A new order would then have to be placed.
