Phillips Industries has introduced two new PermaLogic power-control products, PermaLogic TC and PermaLogic TC Plus. Along with the original PermaLogic dome-lamp controller introduced in 2006, this family of products allows efficient use of the blue trailer accessory wire to operate ancillary devices like interior dome lamps and liftgates.

The PermaLogic TC Liftgate Battery Charging System allows for more frequent liftgate usage because it provides a 14.4-volt charge to the liftgate batteries, charging them to full capacity. In most cases it can eliminate a dual- or single-pole setup. And because it automatically interrupts the charge when the brakes are applied, it allows full power to the ABS system when needed.

PermaLogic TC PLUS combines the Liftgate Battery Charging System and the Dome Lamp Controller into a single nosebox. Trailer dome lamps can be controlled normally and the liftgate charger is used when needed to provide maximum charge.
