Narrow Profile Power Supplies Feature Remote Sensing Capability

February 27, 2008 10:55 am | Comments

Acopian's narrow profile WN8 series of power supplies, with outputs from 3.3V DC to 48V DC and from 120W to 288W, have been recognized for compliance with the requirements of UL508. They can be used on an input of 90V AC to 265V AC or 110V DC to 350V DC. All models have power factor correction and output inhibit capability - applying between +3V DC and +25 VDC to the Inhibit terminal will disable the output.
