The Current PDU, an 8-channel solid-state power distribution unit
Eight channels, one compact unit.
Every channel is a solid-state high-side switch with its own current measurement, PWM control and protection. Four channels are rated for 20 amps and four for 10 amps. Run a single PDU standalone from its digital inputs, or put up to eight units on one CAN bus and command the power of the whole vehicle from your ECU or switch panel.

A drop-in AEM PDU-8 replacement.
Running an AEM PDU-8, or planned your wiring around one? The Current PDU is a drop-in replacement in both form and function. It matches the footprint and connections of the PDU-8 and works in its place out of the box, at almost half the price.
It does more, too. On a newer, higher-quality hardware design, you also get PWM control on every output, a standalone input mode with configurable trigger logic, per-channel current monitoring over CAN and USB, free desktop configuration software for macOS, Windows and Linux, and firmware updates in the field.
Hardware features.
Per-channel current monitoring
Every channel reports its current draw in real time, so you can see what each circuit pulls, in the Configurator or over CAN.
PWM output control
Drive each channel with PWM at a configurable 100–1000 Hz for dimming and reduced-power operation, not only on/off switching.
CANbus control
Command channels and read status over CAN at 125K to 1M baud, with up to eight PDUs on one bus. A public DBC file is provided.
Standalone input mode
No CAN required. Eight digital inputs drive channels directly, with configurable trigger logic, enable and disable delays, and pulse timing.
Built-in protection
Sustained overcurrent shuts a channel down, a short circuit trips at once, and a hardware watchdog turns every output off if anything goes wrong.
Configure and monitor from your desktop.
PDU Configurator is a free desktop app for macOS, Windows and Linux. Connect over USB to set up channels, CAN and input triggers, watch the current draw of every output in real time, and install firmware updates, all from one place.

Quick start.
- Wire 12 V power and ground. If you run several PDUs on one CAN bus, set the ID of each unit (1–8) with its DIP switches.
- Connect over USB and open the PDU Configurator desktop app for macOS, Windows or Linux.
- Pick your mode, CAN or INPUT. Then set the PWM frequency, the CAN baud rate and the input triggers, and save the settings to the unit.
- Command channels over CAN with the public DBC file, or let the digital inputs switch them standalone.
