DESCRIPTION
   The HFS21 motor control module is a special power control module used only for three-phase motor forward and reverse operation. It includes a logic interlock circuit and a delay turn-on circuit. Therefore, when used in motor forward and reverse switching operation, ensure that the switch time is more than 300μs, so that the triac will not cut off immediately, which can avoid damage or destruction caused by incorrect operation and protect the power supply system. The motor and the module itself.
