Sale price $595.00 Regular price $1,295.00

These are USED units that I have been tasked to find a home for which is why the price is so low. I will not be getting any more in stock so act fast while they are still available. These are not a direct drop in type replacement devices as they will need programming and setup by an expert. If you are not familiar with the programming software DVT then please do some more research before purchasing this item.

Are you looking to ship internationally? I don't have an international account with shippers like UPS or FedEx so my rates would be too high but I have had customers use forwarders like It is worth checking into. The package will measure 17inches_x_9inches_x_7inches_(12lbs)

Item Description
The Gen4 range represents a well established design in compact AC controllers. These reliable controllers are intended for on-road and off-road electric vehicles and feature the smallest size in the industry for their power capacity. Thanks to the high efficiency it is possible to integrate these controllers into very tight spaces without sacrificing performance. The design has been optimized for the lowest possible installed cost while maintaining superior reliability in the most demanding applications.
