Additions to the ZPSA series PCB-mountable ac/dc power supplies include the single-output 40W ZPSA40 and 60W ZPSA60 in an industry-standard footprint measuring 2” x 4” x 1.07”. Both components meet the conducted and radiated EMC requirements of EN55022-B and FCC Class B without additional filtering and meet EN61000-4 immunity specs. Accepting an input-voltage range from 90 to 264 Vac (47 Hz to 440 Hz) or 120 to 370 Vdc, they are available with the most popular output voltages from 3.3 to 48 Vdc and their outputs are floating, making them viable for either positive or negative polarity. Typical efficiencies are up to 88%. Other standard features include over-voltage and short-circuit protection. Additionally, the supplies are available as either an open-board configuration with Molex input/output connectors or as a “/P” version with pins for PCB mounting. Prices start at $15.75 each/1,000.
