Alpha's next generation of Obstacle Detection zip motors. Alpha is “Going Green” with the WSERD50-T 20/17 OD zip motor.
A fast, quiet motor that uses less electricity, with a long thermal overload cut-out time, so it won’t trip after a few cycles.
Reliable Obstacle Detection on the way down, and tensioning on the way up.
S001 wind sensor can also be connected to this motor as an additional safety device.
