PCB Supplies Meet Class B EMI
With an industry standard footprint of 2" by 4" by 1.07", the single-output ZPSA40 and ZPSA60 series of compact pcb-mountable AC-DC power supplies from Lambda meets conducted and radiated EMC requirements of EN55022-B and FCC Class B (without additional filtering or components). The power supplies are available with output voltages from 3.3 V to 48 VDC. The outputs are floating so they can be used as either a positive or negative polarity. Typical efficiencies are up to 88%. Accepting an input voltage range of 90 VAC to 264VAC (47 Hz to 440Hz) or 120 VDC to 370 VDC, the power supplies have global safety agency approvals per UL/CSA/EN60950-1. The ZPSA40 or 60 series are available now with prices starting at $15.75 each in 1000 piece quantities.
