TDK Corporation announces the introduction of the five year warranty TDK-Lambda RWS-B series of AC-DC power supplies, designed to provide solid performance at an economical price.  The product line up has four power levels and compact case sizes, rated at 100, 150, 300 and 600W.
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 48Vdc 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 100 and 150W models operate from -10oC to 70 oC with derating above 40 oC and the fan cooled 300 and 600W models up to 70 oC with derating above 50oC.  In addition over voltage and over current 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.
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.
Major applications
  • General industrial and commercial automation, test and measurement, broadcast, LED signage and communications equipment
Main features and benefits
  • Five Year Warranty
  • Compact case sizes
  • UL508 certified (select models)
  • Long service life (conservative electrolytic capacitors ratings)
