| ECS125PS Electronic centrifugal switches for split phase induction Model name：ECS125PS operating voltage：AC 110V, 50/60Hz Application：CSIR 或 CSCR 电动机 (0.18~1.1kW)
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 or outside motor frames
Electrical characteristics (typical)
| Parameter | ECS125PS | Unit |
| Line voltage, VL | 100~120 | VAC |
| Non repetitive peak current @ half cycle, 50/60Hz | 120 | A |
| Thermal impedance @ 7.4sec, 25A | 2.4 | ℃/W |
| Switch-on delay time @ 50/60Hz | 2.0 | Cycle |
| **Forced switch-off locked rotor time | 7.0(8.4) | s |
