Description
SM 2652 4-Quadrant DC Controller is an isolated 4 Quadrant speed controller for separately magnetized or permanent motors. It utilizes speed feedback from the armature voltage (Avf), or from a shaft mounted tachogenerator. It incorporates a fully controlled anti-parallel thyristor bridge for supplying and absorbing power during the forward or breaking conditions.
