Description
A connector for users who need serious power delivery for DC-AC converters in military vehicles.
Do not use this connector for other applications — it is unprotected and can be dangerous if used improperly.
Warning:
This connector carries very high current with minimal protection. Use at your own risk.
Intended for stationary use only
Design the system so that no mechanical force is applied to the connector or cables during operation
This design uses 35mm² cable and is intended to support up to 3000W.
At 24–28V, this means currents up to approximately 125A.
It might jump start Willys jeep, but don't trust it to jump start your M113/Bradley APC.
The overall design is based on the original connector, but with several modifications:
Increased wall thickness for improved mechanical strength
External cable routing
Added friction-lock mechanism to help secure the cable in place
This connector is designed specifically for 35mm² cable and will not properly fit 25mm² cable.
