Lewmar ELS Control Box for EVO Winch - 40ST-12V / 65ST -24VPLEASE NOTE: The 4 terminal version of the box is no longer produced. It has been replaced by the 2 terminal version. You can however still use the 2 terminal version - the current version measures incoming current internally via one of the terminals meaning that there is no need for the additional connections (it essentially has a built in shunt).
Pioneered by Lewmar, ELS (Electric Load Sensing) electric winches are controlled by an Overload Protection Control Box, which allows the winch to be operated up to the safe working load of the specific winch. Once this load is exceeded, the winch automatically cuts out. Once the load is reduced to below the safe working load, the winch can be restarted. The ELS features the additional safety function of a Motor Thermal Trip, which ensures that the motor cuts out in the event of excessive heat build up.
ELS Control Boxes are available on the EVO™ Electric Winch Range Size 40 to 80. |
