Heritage ATS Automatic Transfer Switches
Seamless power transfer between sources to keep critical loads running without interruption.
Overview
The Heritage ATS provides fast, reliable automatic transfer between utility and standby power sources for mission-critical facilities. Available in open-transition, closed-transition (make-before-break), and soft-load transfer configurations, the Heritage ATS ensures that hospitals, data centers, and industrial processes experience zero disruption during power events. Integrated engine start controls and load management simplify generator coordination.
Key Features
- Closed-transition (100 ms overlap) and open-transition transfer modes
- Bypass-isolation configuration for maintenance without load interruption
- Programmable exerciser and load-test sequencing for standby generators
- Withstand and close-on ratings for high available fault currents
- Integrated load-shedding and load-prioritization logic
- Color touchscreen controller with event logging (10,000+ events)
