TDK-Lambda is adding a further 50W power model to its RWS-B series of enclosed AC-DC single output power supplies. Augmenting the four existing power levels between 100W and 600W, the newly launched 50W range of models is well suited to a number of low-power applications including general industrial, automation, broadcast, test and measurement and LED signage.

Operating from a universal input of 85–265V AC (47–63Hz), the RWS50B power supply achieves exceptional thermal performance for cooler operation over its operating range of -10 to +70degC and is convection cooled. Standard output voltages range from 5 to 48V DC, delivering currents up to 10A with typical efficiency up to 88 per cent. To accommodate non-standard system voltages, the RWS-B series is user adjustable by -10/+15 per cent (+10 per cent for 48V model). Regular features include over current protection with automatic recovery and latching over voltage protection.

As with all models in the RWS-B series, the RWS50B features a 10 year e-cap lifetime (or greater under typical operating conditions) and comes with a 5-year warranty. CE marked, according to the Low Voltage and RoHS2 Directives, this 50W power supply achieves 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.
