Lower-Voltage 300W High-Reliability Power Supplies Added
TDK Corporation has announced the addition of 12V and 15V models to its TDK-Lambda ZWS300BAF series of 300-Watt high-reliability power supplies. Operating from a universal input of 85- to 265-Vac, the ZWS300BAF features a 10-year electrolytic capacitor lifetime demanded by manufacturers of industrial, test and measurement, broadcast and communications equipment. The ZWS300BAF series now comprises of 12V, 15V, 24V, 36V and 48V models, each adjustable by up to +/-10% to accommodate non-standard system voltages.
Standard features include over current and over voltage protection and an optional remote on/off or cover is also available. Achieving up to 89% efficiency for the 12V and 15V models, the ZWS300BAF has an operating temperature range of -10 to +70 degrees C, allowing 100% load operation in a 40 degrees C convection cooled environment and 60% load at 70 degrees C with 1.4m/s airflow. There is less than 0.5mA earth leakage current.
With active power factor correction that meets IEC61000-3-2, the ZWS300BAF has a 3kVac input to output isolation and meets conducted and radiated EMC conforming to EN55011/EN55022B and FCC-B. Delivered with TDK-Lambda’s 5 year warranty, the ZWS300BAF is safety certified to UL/CSA/EN60950-1, EN50178 and carries the CE mark to the LV and RoHS Directives.
