TDK Corp. has added 50 W models to the five year warranty TDK-Lambda RWS-B series of ac-to-dc power supplies, designed to provide solid performance at an economical price. The product line up now has five power levels and compact case sizes, including 100, 150, 300 and 600 W.
Operating from a universal input of 47-63Hz, 85-265Vac (300 Vac for 5 seconds), the RWS50-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 & measurement, broadcast, communications and LED signage.
The convection cooled 50 W models operate from -10 °C to 70 °C with derating above 40 °C. In addition over voltage and over current protection is included.
High operating efficiencies of up to 88% 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.
