Features: ASMF-04 single channel Highly Torque 500Nm controller provides powerful torque output capability, suitable for various Highly Torque requirements applications. Highly performances single channel controller with stable performances, accurately controlling torque output. Do not reverse connect the positive and negative poles of power, as reverse connection may burn out controller. The slide end of the angle feedback potentiometer must be connection to the IN end of the corresponding channel, misconnection can cause damage to controller and potentiometer. Adjust angle control scope and sensitivity, great choice for various mechanical system.
