Functional description:
The KLIBO Star-Delta Timer has been specifically developed for star-delta starting of cage motors in mind. Starting times are adjustable and can be set to meet specific application requirements. All other operating sequences are time-optimized and are controlled and monitored by a controller with watch-dog feature. Powerful relays actuate the output signals for star and delta.
