The FP-DCC1 is the ideal choice in many applications where audio or video modules need to be powered from a 12 Vdc source. Ground-referenced RDL modules may be operated from one of the FP-DCC1's two outputs. One is a high current output providing 400 mA @ 24 Vdc intended to power multiple modules (see RDL ST-PD5 Power Supply Distributor for multiple module installations) or RDL audio power amplifiers (such as ST-PA2 or ST-PA6). A second low noise output is heavily filtered and provides 50 mA @ 24 Vdc specifically to power microphone level high gain modules, such as microphone preamplifiers. Both outputs may be used simultaneously.

The FP-DCC1 outputs are regulated to provide 24 Vdc for input voltages normally encountered in 12 Vdc battery circuits. If voltage in excess of 15 Vdc (possible if a vehicle's regulator should fail) is connected to the FP-DCC1 input, the module protects itself by shutting down its internal circuitry and illuminating the INPUT OVERVOLTAGE LED. The FP-DCC1 input and outputs are protected against excessive currents and reverse voltages. The FP-DCC1 is not intended to power floating (bipolar) modules.
