The 41020C10 is a 20A DC to DC converter. The converter is used to provide energy for 12V apparatus from either a 48V or 36V 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, 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 reverse battery, over-temperature, over-current, and short circuit without damage to the unit. FUNCTIONAL DESCRIPTION Connections to the unit are made via a 6 pin Deutsch DT style connector. The terminals are as follows: Pin 1: +48/36V Input Voltage. This pin provides the input voltage to the converter. Pin 2: Ignition. This pin provides a signal that turns the switched output on and off. Pin 3: Ground. This pin should be connected to the system ground. Pin 4: +12V (Memory). This pin is the unswitched output voltage. Pin 5: +12V Switched. This pin is the switched output voltage. Pin 6: Ground.
