TDK-Lambda RWS150B-12 EHFP AC-DC Power Supply

TDK-Lambda RWS150B-12 is a 150 W AC-DC switching power supply that delivers a regulated 12 V DC output up to 13 A. It accepts a wide input range of 85-265 VAC or 120-370 VDC, enabling global operation without a dedicated transformer. The unit supports up to 156 W of output power, with typical efficiency ranging from 84% at 100 VAC to as high as 89% at higher input voltages. Inrush current is typically 16 A at 100 VAC and 32 A at 200 VAC (Ta=25°C, cold start). The 12 V nominal output and 13 A max current are documented for this model within the RWS150B family, and distributors corroborate the same specifications. This power supply is suitable for powering electronics in industrial equipment and other applications requiring a reliable 12 V rail from a broad mains range.
