The encapsulated wide-input dc-to-dc converter line of power supplies is rated up to 60 W. Wide-range dc inputs are set at 9 to 18 Vdc, with output voltages ranging from 3.3 to 48 Vdc and up to 8 A. Threaded mounting holes permit them to be mounted to a chassis, cabinet wall or bracket or they can be DIN-rail-mounted or used on a test bench or tabletop. Input/output isolation prevents ground loops and permits the use of inputs of either polarity; outputs of single output models may be used in either polarity and floated up to 500 V above the input.
