Liebert STS2 StaticTransfer Switch
Provides automatic switching between two different AC power sources such as different UPS systems.
- Automatic switching for dual bus loads
- Requires only front access for easy installation and maintenance
- Offers primary or secondary side switching
- 100% rated, fuseless design
- Operates efficiently
- Front access to all components provides simplifies installation and maintenance, and reduces amount of floorspace required for access.
- Internal CANBUS protocol: high-bandwidth communication between system components via twisted-pair cables.
- Triple redundant logic with dual power feeds.
- Standard on-unit monitoring and optional centralized monitoring capability provide continuous system visibility.
- When applied as primary side switching, cost are lower due to requiring only one power distribution unit, a lower current due to 480V vs. 208V, and lower installation and wiring cost.
