RWS-B Series Power Supplies

TDK Lambda Americas announces the introduction of the five-year warranty TDK-Lambda RWS-B series AC-DC power supplies, designed to provide solid performance at an economical price. The product line has up to four power levels and compact case sizes, rated at 100, 150, 300 and 600 W.

The convection-cooled 100 and 150 W models operate from -10°C to 70°C with derating above 40°C and the fan-cooled 300 and 600 W models up to 70°C with derating above 50°C. In addition, overvoltage and overcurrent protection is included. High 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.

Operating from a universal input of 47-63 Hz, 85-265 VAC (300 VAC 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.
