The PDU-27SS Power Distribution Unit provides centralized power distribution, battery-voltage monitoring, and programmable shutdown control for emergency, public safety, commercial, fleet, and specialty vehicle electrical systems.
The unit combines multiple power-output types in one organized location, including ignition- or timer-controlled outputs, continuous battery outputs, and relay-controlled outputs. This centralized design helps simplify vehicle wiring, improve serviceability, and create a more easily traceable electrical system.
Fourteen outputs can be configured through DIP-switch selection for ignition-controlled or timed operation, while seven additional outputs provide continuous battery power. Four relay-controlled outputs add flexibility for circuits that require ground, normally open, or normally closed switching.
Integrated battery-voltage monitoring and low-voltage shutdown help protect the vehicle battery from excessive discharge. Programmable timed shutdown allows accessory circuits to remain powered for a selected period after vehicle shutdown, while zero-current standby operation helps reduce unnecessary battery draw.
Each output also includes an LED fuse-status indicator, making it easier to identify circuit protection issues during diagnostics and service.
