TDK Corporation is augmenting its TDK-Lambda ZWS-BAF series of single output power supplies with the addition of the 300W model. The ZWS300BAF operates from a universal input of 85–265V AC or 120–370V DC and features a 10-year E-cap lifetime for superior reliability in the field, meeting demands for a wide range of applications, including those found in industrial equipment and front-end equipment for broadcast and communications as well as test and measurement.

Achieving up to 91 per cent efficiency, the ZWS300BAF features an operating temperature range of -10 to +70degC, allowing 100 per cent load operation in a 45degC environment (convection-cooled) and 60degC with 0.7m/s airflow. Offered with output voltages of 24V, 36V and 48V, each model in the ZWS-BAF series can be adjusted by up to +/-10 per cent of its nominal voltage to accommodate non-standard system voltages. Standard features include over current and over voltage protection circuitry and an optional remote on/off is also available.

With active power factor correction (PFC) that meets EN/IEC61000-3-2, the ZWS300BAF has a 3kV AC input to output isolation and meets conducted and radiated EMC conforming to EN55011/EN55022-B, FCC-B, VCCI-B. Delivered with TDK-Lambda’s five-year warranty, the ZWS300BAF is safety-approved to UL/CSA/EN60950-1 and EN50178 and carries the CE mark, according to the LV Directive and RoHS Directive.
