Liebert STS 600 Amp static switch
Static Transfer Switch2, quantity (2) for redundant system, Input 208 Voltage, 3 phase

In addition to the LBS and Power-Tie options, the Liebert Static Transfer Switch 2 (STS2) makes the redundancy truly usable.

The STS2 can be used with a power distribution unit (PDU) or dedicated to a specific piece of load equipment to provide dual power cord functionality.

The STS2 connects to a dual bus power distribution network and makes a nearly instant (less than quarter-cycle) transfer of its connected load from one power source to the other.

Distributed Redundant Configurations
Distribution Options

The first arrangement provides a high level of fault tolerance. A Liebert STS2 ahead of the PDU provides uninterrupted transfers between UPS systems.

The fast switching capability of the static switch provides protection against “fast” power system failures, such as source failures, breaker trips and even operator error. The limitation here is that you still can’t service the PDU when the load is on-line.

The second arrangement has a single-input load receiving power from a static switch on the output of two PDUs.

Liebert’s Precision Power Center (PPC) takes packaged power systems to new heights...literally.

By placing the input and output conduit connections at the top of the unit, the Top-Exit PPC brings the benefits of computer room packaged power systems to non-raised floor applications. In a single cabinet, the PPC combines distribution, computer-grade grounding, isolation, and power monitoring, providing the protection your vital computer equipment demands

Liebert UPS Battery Monitoring(4) Battery cabinets, 160 C & D 12-370’s

Liebert offers the latest in UPS battery monitoring technology with products by Albér — a leader in the field since 1972. Albér technologies by Liebert are designed to indicate potential battery failure, optimize useful battery life, reduce maintenance cost and increase safety.

Like an ultrasound for a battery, this technology lets you “look inside” and assess its true state of health. Liebert battery monitors use a patented Internal DC resistance test method that bypasses the limitations of outdated AC based impedance testing. By tracking internal resistance, the system can predict and report failing conditions prior to complete failure. A life remaining estimate algorithm, which uses discharge parameters and internal resistance readings, assists in predicting remaining battery life.

Liebert Battery Monitoring Systems continuously diagnose all critical battery parameters such as cell voltage, overall string voltage, current and temperature. An alarm sounds for any out-of-tolerance condition. Trend analysis provides the ability to analyze performance and aid in trouble shooting. The Liebert BDS-256XL Battery Monitoring System Is Designed for Large UPS Systems.

The Liebert BDS-256XL battery monitoring system continuously monitors and diagnoses all critical battery parameters for large UPS systems. It can monitor up to 256 cells/modules per string. Tracking and reporting allow a proactive response in replacing a bad battery before it affects others in the string. The modular design easily expands to monitor an unlimited number of strings.
