AC-DC Power Supplies

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 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 new 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 RWS-B series (RWS100B, RWS150B, RWS300B and RWS600B) offers improvements over previous generation products, including up to 5% efficiency gain, 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 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.
