Specially Designed for Contactors
DCM621KH： Restart Contactor Type Anti-Sag Device
1. An anti-voltage sag device specially designed for contactors.
2. After the contactor releases due to voltage sag, this device can pull the contactor back in to restore the motor to normal operation.
3. When a voltage sag occurs, the device is powered by its internal supercapacitor to maintain normal operation. Once the device detects the recovery of the power supply voltage, it closes its internal control node and sends a restart command to the control loop, enabling the contactor to return to the engaged state and the motor to resume normal operation.
4. The restart delay time is adjustable (0–9 seconds).
5. When a large number of motors are used, batch restart can be set.
6. Small size，64mm*96mm*47mm.
7. Magnetic structure, easy installation.
