The "ELS" (Electric Load Sensing) Electric Winches are controlled by and Overload Protection Control Box, this allows the winch to be operated up to a high load, equivalent to the SWL (Safe Working Load) of each winch size. When this load is reached the winch automatically cuts out. If the load is reduces the winch load can be increased back up to this cut out level. Safety Overload Cut Out function was pioneered by Lewmar, and is a unique Lewmar features. A Motor Thermal trip is connected as an extra safety feature to ensure a motor cut out, if the heat builds up to an unacceptable level.
With Lewmar electric winches, the sheet is recovered rapidly at low load when sheets are slacker, and slows down as load increases. This provides speed when you need it most, and control as you tune your sails to perfection.
