TDK Corporation is launching a 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 85–265V AC (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.
This new RWS-B series (RWS100B, RWS150B, RWS300B and RWS600B) offers significant improvements over previous generation products, including up to 5 per cent efficiency gain (the 150W RWS150B-24 model, for instance, achieves a typical efficiency of 89 per cent), and a reduction in size to help ease system integration.
Standard output voltages range from 5 to 48V DC, delivering currents up to 100A. To accommodate non-standard system voltages, the RWS-B series is user adjustable by -10/+15 per cent (+10 per cent 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 +70degC; 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.
