The QPS-45 Series is a 45W single-output open-frame power supply designed for applications requiring compact, fanless operation. It supports universal AC input from 90VAC to 264VAC and offers four output voltage options: 5V, 12V, 24V, and 48V, with corresponding rated currents of 8.0A, 3.7A, 1.9A, and 1.0A. The unit measures 101.6mm x 51mm x 28mm and mounts via M3 screws with a maximum torque of 6.0kg.cm. Operating temperature ranges from -10°C to 60°C with free air convection cooling. Efficiency reaches up to 86% at 48V output. Protection features include over-load, over-voltage, and short-circuit protection with auto-recovery. It meets CB, GB4943, and EN60950-1 safety standards, and complies with EN55022 Class B EMI limits. Isolation withstands 3.0kVAC between primary and secondary. MTBF exceeds 200,000 hours at 25°C full load.
