The PU-25 series of 25W open-frame switching power supplies accept a universal input of 85 to 265 vac via an integral IEC-320-style input connector and delivers single or dual voltages of from 5 to 25 vdc. The supplies measure 4" x 2" x 1.1", making them suitable for medium-power designs where space is limited. Other features include a line/load regulation of ±0.3%, ripple and noise of 50 mVp-p, typical efficiencies of 77%, and an input-to-output isolation of 3 kvac. The switcher conform to UL, CSA, TUV, FCC/B, and VDE Level B EMI standards. And utilizing convection cooling, they can operate over an ambient temperature range of 0°C to 50°C without output derating. Prices start from $13 each in OEM quantities, with delivery from stock to two weeks ARO.
