AC/DC Power Supplies

An AC/DC power supply converts mains AC into the regulated DC voltage a device runs on, and we supply open frame, enclosed, and external units from 4 W to 1,600 W, including medical-grade models. The choice comes down to the power and number of outputs, the form factor (an internal open frame, U-chassis, or enclosed unit, or an external adapter), the safety approvals the end product needs, and how the supply is cooled and controlled, including digital interfaces such as PMBus, CANBus, and Modbus. Beyond more than 13,000 standard products, we offer modified and fully custom designs with private labeling, and manufacturing options outside China. We specify the supply with the display and computer it powers, so the power for the whole system is designed once.

How to choose

Open frame or enclosed: open frame units mount inside the equipment's own enclosure; enclosed and U-chassis units carry their own cover and mounting.
Baseplate-cooled bricks: fanless modules that pass heat into a chassis or cold plate, for sealed or silent equipment.
Multiple outputs: configurable units supply several rails from one 1,200 W supply, with 5 to 16 outputs.
External adapters: from 18 W to 240 W, including USB-C Power Delivery, for equipment that takes its power from outside the enclosure.

Medical power supplies

Medical-grade AC/DC supplies cover external adapters for Class 1 and Class 2 equipment, and internal supplies up to 600 W in compact chassis, open frame, sealed, and fan-cooled designs.
