KLIBO-Star-Delta-Timer
For the automatic start of star-delta.
Description
Features
- Adjustable ramp-up time
- Relay outputs 5A
- Controller-controlled with watchdog
- Specifically designed for star-delta starting of squirrel cage motors
Functional Description
The KLIBO star-delta timer is specifically designed for the star-delta starting of squirrel cage motors. The starting times can be individually adjusted to the respective application. All other switching sequences are time-optimized and controlled and monitored by a controller with a watchdog. The output signals for star and delta are switched by powerful relays.
