effectiveness, reduced training time, and less chance of operator error.

The Key To High-Availability Power

The Liebert Static Transfer Switch2 (STS 2) provides an automatic, seamless transfer between the outputs of two independent UPS systems and the input of a critical load in a dual-bus power system. If the primary UPS should fail, the switch will automatically transfer the loads to the surviving UPS. For redundancy, the Liebert STS2 features three separate, self-correcting logic modules. Each controller is capable of working independently and each helps monitor the other two. Available in capacities ranging from 100 up to

1000 amps.

True Front-Access Design

All mechanical and electronic components of the Liebert STS2 are accessible from the front of the unit. This gives you several immediate benefits:

Greater freedom in system design. The Liebert STS2 can be placed adjacent to or in back of other equipment. It can also be placed against

a wall or partition.

Simplified installation, with ample space for cable connections through top and bottom access plates

Less floor space required for maintenance access. Simplified maintenance, with all key components visible, serviceable and removable from the front of the unit, without the need to shut down the connected load.

Other Features Of The Liebert

Static Transfer Switch2:

Internal CANBUS protocol provides high-bandwidth communication between system components

via twisted-pair cables. Options can be added as simple network nodes

Internal dual-bus control power

Simplified installation and maintenance

Full range of communications options to fit any monitoring strategy

Three-pole switch configurations

True Internal Redundancy

The Liebert STS2 has triple-redundant logic. Each DSP controller is capable of working independently, and each helps monitor the other two. If one malfunctions, the other two lock it out. Each controller has power feeds from both power supplies.

The two power supplies feature true dual-bus power distribution. Both have dual inputs, one from each AC input source. All power connections have diode protection, so that internal or external faults cannot propagate. The result is a rugged, fault-resilient package that is optimized for real-world applications.
