100W to 600W RWS-B Series of AC-DC Power Supplies
Posted : 07 Apr 2014
TDK Corporation announces the launch of its new RWS-B series of enclosed AC-DC single output power supplies. Available in four power levels between 100W and 600W, the TDK-Lambda RWS-B models operate from a universal input of 85 - 265Vac (47 - 63Hz) to meet a wide range of applications, including industrial, test & measurement, broadcast, communications and LED signage. The RWS-B range features a 10 year e-cap lifetime (or greater under typical operating conditions) for high reliability and comes with a 5-year warranty.
The new RWS-B series (RWS100B, RWS150B, RWS300B and RWS600B) offers significant improvements over previous generation products, including up to 5% efficiency gain (the 150W RWS150B-24 model, for instance, achieves a typical efficiency of 89%), and a reduction in size to help ease system integration.
Standard output voltages range from 5 to 48Vdc, delivering currents up to 100A. To accommodate non-standard system voltages, the RWS-B series is user adjustable by
-10/+15% (+10% for 48V models). Regular features include over current and over voltage protection circuitry.
All models offer outstanding thermal performance for cooler operation over their operating temperature range of -10 to +70°C; the RWS100B and RWS150B models are convection cooled, whereas the higher power models incorporate an internal cooling fan.
The TDK-Lambda RWS-B series offers curve B conducted and radiated EMI performance (EN55011/EN55022-B, FCC class B, VCCI-B) and is approved to a wide range of safety standards including UL/ CSA/EN60950-1, UL508 (on certain models) and carries the CE mark, according to the Low Voltage and RoHS2 Directives.
