TDK-Lambda's new ZWS150BP and ZWS240BP power supplies deliver 150 and 240 W, respectively, over an operating temperature of -10 to 50 °C at 100% load with efficiencies up to 91%.

TDK Corporation has announced the new TDK-Lambda ZWS-BP series of single-output, PCB-type AC-DC power supplies. Based on the popular ZWS series, the ZWS-BP is 30% smaller than its predecessor, thus simplifying equipment design and is offered in two mid-power output models - ZWS150BP (150 W) and ZWS240BP (240 W). With a 200% peak-power capability, the ZWS-BP is well suited for electromechanical equipment, such as motors, disk drives, pumps, fans, and actuators that require a high initial start-up current. The ZWS-BP is equally well suited for a wide range of light industrial equipment and front-end equipment for broadcast and communications applications and for applications in indoor and outdoor LED lighting and signage and test & measurement. Operating from a universal input of 85 to 265 VAC or 120 to 370 VDC, the ZWS-BP series is a compact product that offers an efficiency of up to 91%. All models are convection cooled with an operating temperature of -10 to 50 °C at 100% load, derating to 75% load at +60 °C. Rated with nominal outputs of 24, 36, and 48 V, with each model being user adjustable by up to 10%, the ZWS-BP series can accommodate a wide range of non-standard system voltages. Standard features include PFC (power factor correction) and over-current and over-voltage protection. Options include a remote on-off feature, conformal coating of the PCB, L-plate or L-plate plus cover, and an additional terminal block (240 W models only). The ZWS-BP series from TDK-Lambda meets the conducted and radiated EMC requirements of EN55011/EN55022-B, FCC-B, and VCCI-B as well as IEC61000-4-2, -3, -4, -5, -6, -8, -11 immunity and safety approvals to UL/CSA/EN60950-1 and EN50178. Delivered with TDK-Lambda's 5-year warranty, backed up with a 10-year electrolytic capacitor lifetime, the ZWS-BP series carries the CE mark, according to the LV Directive.
