operating voltage :AC 220V, 50/60Hz Application: CSIR or CSCR Motors (0.18~3.7kW)

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
Discharge start capacitors with built-in resistors
Electrical characteristics (typical)
| Non repetitive peak current @ half cycle, 50/60Hz | 240 | A |
| Thermal impedance @ 8.0sec | 0.8 | ℃/W |
| Initial switch-on delay time | 2.0 | Cycle |
| * Discharge resistance | 10.0 | KΩ |
| ** Forced switch-off locked rotor time, 60Hz (50Hz) | 7.0(8.4) | sec |
| ** Maximum Number of successive restarts | 9 | - |
| Forced switch-off starting coil voltage | 320~350 | VAC |
| Dielectric strength, between case and pins | 2500+ | VDC |
| Insulation resistance, between case and pins | 10+ | MΩ |
| Ambient air temperature | -20~60 | ℃ |
* For frequent (heavy duty) restarts, it is recommended to connect an additional discharging resistor in parallel with a starting capacitor.
** These are initialized by either a power interruption or a successful motor run state.
