100W to 600W Power Supply Series Has Five-Year Warranty

TDK Corporation has introduced TDK-Lambda RWS-B series of ac-dc power supplies, designed to provide solid performance at an economical price and featuring a five-year warranty. The product line up has four power levels and compact case sizes, rated at 100-, 150-, 300- and 600-W. Operating from a universal input of 47-63Hz, 85-265Vac (300Vac for 5 seconds), the RWS-B series is available with nominal outputs of 5-, 12-, 24- and 48-Vdc with an adjustment range of a minimum of +/-10%. The series is designed to meet a wide range of applications, including industrial, test and measurement, broadcast, communications and LED signage.

The convection-cooled 100- and 150-W models operate from -10 to 70 degrees C with derating above 40 degrees C and the fan-cooled 300- and 600-W models are rated for operation up to 70 degrees C with derating above 50 degrees C. In addition over voltage and over current protection is included. Operating efficiencies of up to 89% reduce internal waste heat and component temperatures, resulting in electrolytic capacitor service life ratings of at least ten years.

The TDK-Lambda RWS-B series is certified to the safety standards of UL/CSA 60950-1, UL508 (on certain models), is CE marked according to the Low Voltage, RoHS2 Directives, and additionally evaluated to EN 60950-1. All models offer curve B conducted and radiated performance to EN55011/EN55022-B, FCC class B and VCCI-B.
