Samusco ECS 125PS Electronic Centrifugal Switches for Capacitor Start/Run Motor

Description

Electronic Centrifugal Switches for Capacitor Start (& Run) Induction Motors ECS 125P Specifications subject to change without notice. Revision 4.0 ECS 125P Model chart * These models are designed for both capacitor start motors and two (start + run) capacitors motors. For motor operating voltage of 220VAC, Please refer to data sheet in photos for full specs.
Electronic Centrifugal Switches (ECS) is a reliable solid-state switch that would duplicate the functions of the conventional centrifugal switch with additional benefits of the electronic device.  Speed voltage induced in a start winding is constantly moitored by the voltage sensing circuitry of ECS, and the internal micro-controller calculates motor speed-torque curve in order to interrupt the start winding current at the point of breakdown torque detected.  At this point, the motor speed normally accelerates to 60-80% of the synchronous speed.  When the motor encounters overload conditions or the motor speed decreases to approximately 20-40% of the synchronous speed, ECS reconnects the start winding.
