SDDR-D Applications
✔ Continuous combined conveyor systems, chemical plants with batch processing.
✔ Conveying devices in steel mills, textile factories.
✔ Electromagnetic contactors for motors with special loads
SDDR-D Instantaneous Power Failure Restart Relay
✔ In the event of a momentary voltage drop that causes the entire batch processing operation to stop, all related motors must be restarted to resolve the issue.
✔ The maximum setting time for power-off delay is 10 seconds, and to restart sequentially according to the load, the restart delay time can be set up to 99 seconds.
Power-off Delay Time: 0.1~10 seconds
Restart Delay Time: 0~99 seconds
