Datasheet

Available in five power levels between 50 and 600W, TDK-Lambda has announced the RWS-B series of enclosed AC/DC single output power supplies. The series operates from a universal input of 85-265VAC to meet a wide range of applications, including industrial, test & measurement, broadcast, communications and LED signage.

The RWS50B, RWS100B, RWS150B, RWS300B and RWS600B offers significant improvements over previous generation products, including up to 5% efficiency gain (for example, the 150W RWS150B-24 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 or +15% (+10% for 48V models).

All models offer outstanding thermal performance for cooler operation over their operating temperature range of -10 to +70°C; the RWS50B, RWS100B and RWS150B models are convection cooled, whereas the higher power models incorporate an internal cooling fan. Other features include over current and over voltage protection circuitry.

TDK-Lambda's 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.

The RWS-B series features a 10 year e-cap lifetime (or greater under typical operating conditions) for high reliability and comes with a five year warranty.
