The LCM300W-T-4 is a 300 W AC-DC bulk front-end power supply designed for industrial and medical applications, featuring a 48 V nominal output with an adjustment range of 43.0 to 60.0 V and maximum continuous output current of 6.3 A. This unit delivers 310 W maximum continuous power and achieves greater than 91% efficiency at full load with 230 VAC input, incorporating robust screw terminals, variable-speed smart fans controlled by DSP, and comprehensive industrial and medical safety approvals including UL62368-1, IEC 60601-1 Ed 3, and RoHS 3 compliance. The power supply operates across an input range of 90 to 264 VAC (47 to 63 Hz), maintains output regulation within ±2% combined line/load/transient, and features optional 5 V @ 2 A housekeeping output with PMBus compliance for advanced power management. Its compact dimensions of 1.61" × 4.0" × 7.0" and operating temperature range of -40°C to +70°C with linear derating make it ideal for mission-critical embedded power applications requiring high reliability and efficiency.
