Trailer Charger with Extender Kit

The Trailcharger is a specially designed DC/DC converter that is used to charge a battery from a 12V source. An example is the battery that is mounted on the trailer of a vehicle. The distance between the alternator of the vehicle and the trailer-mounted battery makes it difficult to get adequate voltage to the battery.

The Trail Charger provides a temperature compensated output optimized for recharging automotive batteries. An LED indicator is provided as a simple means to determine operation. The LED glows when the Trail Charger is running and is supplying current. The Trail Charger Converter is designed to withstand the severe electrical environment of heavy-duty trucks and off highway equipment. The converter can withstand load dump, reverse battery, short circuit, and over-temperature without damage to the unit.

The Trail Charger with lock outs monitors the brake light signal and turns the Trail Charger off when the brakes are activated. Model 11020CLO can also monitor the trailer dome lamps and when the trailer dome lamps are on, the Trail Charger reduces the maximum output current.

The Extender Kit provides an external control module that allows the Trail Charger to have extended run time when the tractor is off without impairing the tractor’s ability to start.

The system offers the same features of a Trail Charger, but is powered by a single or dual pole connector. The external control module controls the Trail Charger allowing extended run time while the tractor is turned off while maintaining the balance between the tractor and trailer. The Extender will not allow the Trail Charger to continue to charge the lift gate batteries, if the tractor batteries are at a low state of charge.
