LCM300 Series – 310–350 WATT FRONT-END AC-DC POWER SUPPLIES

The LCM300 series of enclosed front-end AC-DC power supplies comprises five single output models, providing standard voltages of 12 V, 15 V, 23 V, 36 V or 48 V, plus a 5 V standby output. Each model accepts a universal input of 90–264 Vac, carries medical safety approvals and has a typical full load efficiency of 91%. These PMBus™-compliant digitally controlled power supplies offer a high level of modification flexibility for application-specific functions such as special battery charging and management, peak load handling, voltage control and fan speed profiles. Housed in a compact 4 x 7 inch enclosure that is less than 1U high, LCM300 power supplies incorporate built-in smart fans for cooling and can deliver up to 310 watts of output power. The 24 V and 36 V models can deliver up to 350 watts at operating temperatures up to 45˚C.
