Datasheet
Datasheet Summary
Powered by GS/AI

The KWS15A-12 is a 15W board-mount AC-DC power supply with a 12V output, designed for industrial applications. It operates from 85-265Vac input, features Class II double insulation, and meets IEC/UL/CSA/EN62368-1 and 60950-1 safety standards. The device achieves 83% efficiency at 230Vac and 81% at 115Vac, with maximum ripple and noise of 240mV. It supports an operating temperature range from -40°C (start-up) to +85°C, with derating above 45°C, and complies with EN55011/EN55032-A, FCC-A, and VCCI-A EMI standards. The package measures 50.8 x 25.4 x 24mm and weighs 60g. Hold-up time is 30ms at 230Vac, and it has <0.5W no-load power consumption. Overcurrent and overvoltage protections are included, with no minimum load required. Parallel operation is not supported.
