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.

Notes: (1) All multi-output units may be operated at no-load without damage. At no-load, output tolerance increases to 10%.
(2) Suffix codes for mechanical format and input range are as follows. PD40-XXYZ; “XX” is the model code from the
above table, “Y” is the input range (L=10-30 VDC, M=20-60 VDC, H=30-90 VDC) and “Z” is the mechanical format
(A=open PCB, B=L-bracket, C=enclosed), e.g. PD40-31MC (20-60 VDC input range, enclosed).
(3) “L” series is suitable only for 75% of the above stated maximum output power.
