LRS-350-48 48V 7.3A 350W Industrial Switching Power Supply, 90-264VAC Input, 89% Efficiency, Short Circuit/Overload Protection

The LRS-350-48 is a 350W industrial-grade switching power supply designed for demanding applications. It converts 90-264VAC (switch-selectable) or 240-370VDC input into regulated 48V DC output at 7.3A (350.4W max) with 89% peak efficiency. The unit features a compact 1U-height design with integrated cooling fan that enables full-load operation across an extended temperature range of -25°C to +70°C. Advanced protection mechanisms include automatic recovery from short circuit, overload (115-150% power derating), overvoltage (48-54V range), and overtemperature conditions. With <0.75W standby power consumption, it exceeds energy-saving requirements while maintaining operational readiness. The rugged metal housing withstands 5G vibration and supports 5000m altitude operation. Safety certifications include UL62368-1, CE, and RoHS compliance. Ideal for powering industrial control systems, telecommunications equipment, LED displays, and automated machinery requiring stable DC power. Dimensions: 215×115×50mm (L×W×H). Includes power-on LED indicator, terminal block connections, and 3-year manufacturer warranty.
