Description
These are the Compact version of the popular 4 Amp High Voltage Winch Controllers.

This is the brute force method of motor control.

These controllers don't have the voltage limitations that the MOSFET winch controllers have!

Rather than relying on semiconductor components to take care of power switching, these units make use of relay contacts. This means super low "on" resistance which ensures that the maximum amount of power will be delivered to your winch.

These controllers are recommended for servo winch operation but they will work on 3Racing and RC4WD DC powered winches too.


** So just how much voltage can these things handle? **

The contacts in the relays all exceed 20 volts. This is way more voltage than any servo winch or 3Racing etc winch can safely work with. The actual relay controls will work with up to 10V.

Keep in mind that as you increase the working voltage, you increase the current flowing through the relay contacts to your winch motor.

Plug the controller into a free three position or linear channel on your receiver. Connect a battery that you want to run the winch to the other connector.

The controller only uses a small amount of power from the receiver to power its signal decoding electronics and to operate the relay coils.

When the winch is not winding in or out, the relay contacts provide a short across the motor to "brake" the winch load which helps to keep the line from winding out.

These controllers require a 3 position switch on your radio and can run on up to 10V from your RX. JST plug NOT included.

Compact vs. Standard size.

The compact version has a controller footprint that is roughly 25mm x 14mm x 10mm
Standard size is 33mm x 20mm x 14mm
