The WEHO LRH-50W is a series of 50W single output power supplies, accommodating a wide input voltage range of 300-450VAC or 420-635VDC. Four models are available, delivering 12V/4.2A (LRH-50-12), 15V/3.4A (LRH-50-15), 24V/2.2A (LRH-50-24), and 48V/1.1A (LRH-50-48). These CE-marked units feature efficiencies ranging from 86% to 90%, ±0.5% inlet and load stability, and a ±10% adjustable DC output voltage. Ripple and noise are well-controlled (120-200mVp-p). Comprehensive protections include overload (110-150% auto-recovery), overcurrent, and short-circuit. The supplies operate reliably from -20°C to +70°C, measure a compact 99x82x30mm, and weigh 0.23kg, making them suitable for diverse applications.
