Triple 50A Anderson Plug Extension Lead Ignition/Trigger Wire for DC-DC Chargers
Extend your existing triple 50A Anderson connection between a DC-DC charger and the vehicle's Smart Alternator ignition/trigger signal without re-running new wiring.
This triple 50A Anderson plug extension lead is built for DC-DC charger installs that rely on a triple Anderson (3-pin) connection positive, negative, and an ignition/trigger wire for the charger's "vehicle on" signal. It's the go-to setup for chargers wired to a Smart (variable voltage) Alternator, where the DC-DC unit needs a genuine ignition-on signal rather than reading alternator output directly. If your triple Anderson connection needs to reach further charger relocated to a canopy, drawer system, or second battery box further from the engine bay this lead extends it cleanly with matched connectors on both ends.

FAQ
Q: What is a triple 50A Anderson extension lead used for?
A: It extends an existing triple 50A Anderson connection positive, negative and ignition/trigger wire so a DC-DC charger can be positioned further from the original connection point. It's commonly used where the charger has been relocated to a canopy, drawer system or second battery box.
Q: Why does the lead have a separate ignition/trigger wire?
A: DC-DC chargers paired with a Smart (variable voltage) Alternator need a genuine ignition-on signal rather than reading alternator output directly, since Smart Alternators don't hold a constant voltage. This lead carries that ignition/trigger signal on its own 4mm single core conductor alongside the main power circuit.
Q: What cable and connectors does this lead use?
A: The power circuit runs on 13mm (6 B&S) twin core cable, sized to suit a 50A Anderson connection, with a 4mm single core wire for the ignition/trigger signal. Both ends terminate in a triple 50A Anderson plug.
Q: What lengths are available?
A: This extension lead is available in 500mm, 1m, 2m, 3m, 5m and 6.5m lengths to suit different install distances.
Q: Is this lead protected against abrasion?
A: Yes. The full length is covered in split conduit sleeving, which protects the cable from rubbing, heat and general wear in engine bay, canopy and under-vehicle installs.
Q: Is this lead Australian Made?
A: Yes. It's made using Australian Made cable, covered under Bluebar's Australian Made certification.
Q: Can I get a custom length?
A: Yes. If none of the standard lengths (500mm 6.5m) suit your install, contact us with the length you need and we'll quote it made to order.
