| ECS225PS Electronic Centrifugal Switches for Resistance Start Motors Model name：ECS225PS operating voltage：AC 220V, 50/60Hz Application： RSIR Motors (0.18~2.2kW)
IEC/ EN 60730-1 (Automatic electrical controls for household and similar use) IEC/ EN 60730-2-10 (particular requirements for motor-starting relays) |
Description
This model is a MCU embedded electronic switch that is
designed to activate or deactivate a semiconductor device,
TRIAC, as a function of the motor rotating speed and the
corresponding motor starting torque.
Feature
Extended life span of switching contacts
High compatibility with various motor designs
Improved motor starting efficiency
Neither switching noise nor trembling of contacts
Protect auxiliary windings or start capacitors
Return immediately from unwanted reverse motor rotation
Mounted on either inside / outside motor frames
