The LRS-450-12 is an industrial-grade 12V 450W enclosed power supply designed for demanding automation, control systems, and equipment. It delivers 37.5A continuous current with up to 90% efficiency, reducing heat and energy costs.
Engineered for Tough Conditions:
- Operating temperature: -20℃ ~ +70℃ (forced air cooling, derating above 50℃)
- 5G vibration resistance (10-500Hz) – no loose connections
- 5000m altitude capability – perfect for highland factories
- Humidity: 20~90% RH non-condensing – resists moisture
Smart Protection Features:
- Short circuit / Overload / Over-voltage / Over-temperature protection
- Unique overload response: constant current limiting for 3 seconds before shutdown – absorbs inrush currents from solenoids and motors without nuisance tripping
- Automatic recovery after fault removal – reduces downtime
Safe & Electrically Quiet:
- Compliant with UL 62368-1, GB 4943.1, BS EN/EN61558, EAC TP TC 020
- Low leakage current (
- Low EMI – won't interfere with PLCs, HMIs, or sensors
Easy Installation:
- Compact 1U size: 225 × 124 × 35mm – fits shallow control cabinets
- Screw terminals with clear marking
- Switch-selectable AC input (90-132VAC / 180-264VAC) – be sure to set correct voltage before wiring
Applications: Industrial automation (solenoid valves, relay arrays, sensors), 3D printers, CNC machines, LED lighting, security systems, and test equipment.
3-year warranty.
