描述

The LCM300Q-T is a 300 W AC-DC bulk front-end power supply designed for industrial and medical applications, featuring a 24 V nominal output with an adjustment range of 19.2 to 28.8 V and maximum continuous output current of 14.5 A. It delivers 360 W maximum continuous power and achieves greater than 91% efficiency at full load with 230 VAC input, incorporating variable-speed smart fans controlled by DSP to optimize cooling and extend operational life. The unit operates across a wide input range of 90 to 264 VAC (47 to 63 Hz), maintains output regulation within ±2% combined line/load/transient, and includes comprehensive industrial and medical safety certifications including UL62368-1, IEC 60601-1 Ed 3, and RoHS 3 compliance. With robust screw terminals, optional 5 V @ 2 A housekeeping output, PMBus compliance for power management, and operating temperature range of -40°C to +70°C with linear derating, the LCM300Q-T is ideal for mission-critical embedded power applications requiring high reliability and precise voltage regulation.
