The LCM300 series of closed front-end AC/DC power supplies consists of five single output models providing standard voltages of 12V, 15V, 23V, 36V or 48V as well as a 5V standby output. Each model accepts universal input from 90-264 VAC, has medical safety approvals, and has a typical full load efficiency of 91%. These PMBus™ compliant digitally controlled power supplies offer a high level of customization flexibility for application-specific features such as dedicated battery charging and management, peak load handling, voltage control, and fan speed profiles. Housed in a compact 4 x 7 inch chassis that is less than 1U high, the LCM300 power supplies include integrated intelligent fans for cooling and can deliver up to 310 watts of output power. The 24V and 36V models can deliver up to 350 watts at operating temperatures of up to 45˚C.
