The LRS-450-12 industrial-grade switching power supply delivers 12V DC output at 37.5A (450W) with 90% operational efficiency. Engineered for demanding applications, it accepts wide-range AC input (90-132VAC/180-264VAC via selector switch) and DC input (255-370VDC). The unit features active power factor correction (PFC >0.95) for reduced harmonic distortion and complies with global energy efficiency standards. Protection mechanisms include automatic recovery from overload/short-circuit conditions, over-voltage cutoff, and thermal shutdown with automatic restart. The aluminum alloy enclosure with IP20 rating and dual cooling methods (convection + temperature-controlled fan) ensures reliable operation between -30°C to +70°C. Compatible with DIN rail or surface mounting, it's ideal for factory automation, broadcast equipment, security systems, and renewable energy installations. Safety certifications include UL62368-1, CE, and RoHS compliance. Package includes terminal block connectors, mounting brackets, and comprehensive user manual. Dimensions: 215mm × 115mm × 50mm (8.46'' × 4.53'' × 1.97''). 3-year manufacturer warranty included.
