40 WATT DC TO DC CONVERTERS

DESCRIPTION

The PD40 series of DC/DC converters provide up to 40 watts

of continuous output power. Available in three standard input

ranges of 10-30 VDC, 20-60 VDC and 30-90 VDC, they are

ideal for a variety of applications including telecoms, process

control,

portable

equipment

and

vehicle

mounted

instrumentation. All units are available in compact “open PCB”

or “enclosed” mechanical formats.
