With typical efficiency of 87.5%, fanless free-air convection cooling, and a slim 159 × 97 × 30 mm metal mesh case, it fits 1U/tight enclosures while maintaining excellent thermal performance from -30°C to +70°C. Built-in short circuit, overload, over voltage, and over temperature protection improve system safety. A power-on LED, low no-load consumption, 5G vibration resistance, and 3-year warranty make the LRS-150-12 a reliable, cost-effective choice for demanding 12V industrial applications.
150W High Capacity: 12V @ 12.5A, suitable for larger LED loads, PLCs, relays, motors drivers, and multi-device 12V systems.
Switch-Selectable Universal Input: 85–132 / 170–264V AC and 240–370V DC; withstands 300V AC surge for 5s.
Slim Fanless Industrial Design: Only 30mm profile, metal mesh enclosure, free-air convection, silent and low-maintenance.
Complete Protection Set: Short circuit, overload (110–140%, hiccup/auto-recover), over voltage (13.8–16.2V), and over temperature protection.
Field-Proven Reliability: -30°C ~ +70°C operation, 5G vibration resistance, power-on LED, MTBF 601K hrs, UL/TÜV/CCC/CE-class safety, 3-year warranty.
