THEORY OF OPERATION
The 21020C00 is a 20A DC to DC converter. The converter is used to provide energy for 12V apparatus
from a 24V source.
The converter provides both a switched output and an unswitched output. The switched output responds
to the IGNITION input. When the IGNITION input is active then the switched output is on. The feature is
primarily used when the converter is used to power a radio with memory requirements. When used with a
radio, the unswitched output provides power for the radio memory. If a switched output is not required
then the unswitched output should be used, and the ignition and switched output pins can be left
unconnected.
The converter is designed to withstand the severe electrical environment of the heavy-duty trucks and off
highway equipment. The converter can withstand load dump, reverse battery, over-temperature, overcurrent, and short circuit without damage to the unit.
FUNCTIONAL DESCRIPTION
Connections to the unit are made via a 6 pin Deutsch connector. The terminals are as follows:
Pin 1:
Pin 2:
Pin 3:
Pin 4:
Pin 5:
Pin 6:
+24V Input Voltage. This pin provides the input voltage to the converter.
Ignition. This pin provides a signal that turns the switched output on and off.
Ground. This pin should be connected to the system ground.
+12V (Memory). This pin is the unswitched output voltage.
+12V Switched. This pin is the switched output voltage.
Ground (Optional). This pin is common to pin 3.
