Mean Well LRS-150-12 AC-DC Switching Power Supply

The Mean Well LRS-150-12 is a compact 150 W AC-DC switching power supply that delivers a regulated 12 VDC output for industrial automation, control panels, PLC cabinets, HMI systems, LED equipment, and factory machinery. It provides 12.5 A of output current with a single channel and an adjustable output range of 10.2–13.8 VDC, and accepts universal input from 85–264 VAC or 120–373 VDC (nominal 100–240 VAC, 47–63 Hz). The unit uses free-air convection cooling and includes protections for overload (105–150% of rated output), overvoltage (13.8–16.2 VDC), short circuit, and overtemperature, along with a no-load power draw under 0.5 W. Efficiency reaches up to 87.5%, and it tolerates an operating range of -30°C to +70°C with dimensions 159 × 97 × 30 mm and a weight of about 0.43 kg. Mounting is chassis/panel, and it carries safety certifications including IEC/EN 62368-1, UL 62368-1, EN 61558-1, plus CE, UL, CB, TUV, and RoHS. Common replacements include NES-150-12, RSP-150-12, and SDR-240-12.
