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.
