LCM300 Series
Active
310 to 350 W 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. The series is medical-safety approved and accepts a universal input of 90 to 264 VAC with a full-load efficiency of 91%. These PMBus®-compliant digitally-controlled power supplies offer a high-level modification flexibility for application-specific functions such as special battery charging and management, peak load handling, voltage control, and fan speed profiles. Compactly housed in a 4 x 7 inches enclosure less than 1U high, the power supplies incorporate built-in smart fans for cooling and deliver up to 310 W of output power. The 24 V and 36 V models can deliver up to 350 W at operating temperatures up to 45˚C.
