Secure Power for Guaranteed Business Continuity

Mission-critical applications require a highly available power supply. The SOCOMEC UPS Static Transfer System (STS), STATYS, provides the highest availability values of permanent power supply, essential for service continuity.

STATYS protects against:

Main power outages
Operator errors
Failures in the upstream power distribution system
Failures caused by faulty equipment supplied by the same source

User benefits of Static Transfer Systems:

Provides redundant power supply to mission
Increases the power availability by choosing the best quality supply
Prevents fault propagation
Optimises the use of the power sources during load transients
Facilitates infrastructure maintenance without application shutdown
Allows easy extension and infrastructure design of the architecture

In addition, UPS STATYS offers the following benefits:

Minimal heat dissipation
High short circuit capability
Clear and easy to use human interface
Full internal redundancy for maximum fault tolerance
Fast and easy front access to every internal component
Independent source management
Wide range of communication protocols management
Full compliance to the latest standards and CBEMA / ITIC recommendations for critical loads

Flexibility and adaptability, STATYS is designed to provide:

Redundancy from two alternative and independent power sources
Instantaneous manual and automatic transfer
Selection of preferred source by the operator
Programmable re-transfer after an automatic transfer
Programmable automatic restart
All pole switching possibilities to keep source fully separated providing compatibility with all types of earthing systems
Easy operating thanks to a comprehensive control panel with mimic diagram and display
Fast output fault current sensing, preventing the transfer of the faulty equipment to the opposite circuit. Disturbances such as short-circuits on any other equipment can be avoided
Double interlocked maintenance bypass
Comprehensive communication facility, SNMP, JBUS/MODBUS, HTTP
Ethernet connection to a LAN connection for remote monitoring by the customer (MODBUS TCP)
Tele-maintenance connection

Transfers: Switching mode

Depending on the source state, the transfers can be either synchronous or asynchronous. The switching operation is extremely fast and secured and is a “break before make” transfer.

The two sources are never cross connected, thus avoiding any risk of overlapping of power sources during transfer.

Backfeed protection

To be compliant with the standard IEC 62310-1, STATYS is fitted with a “backfeed” protection system to protect against possible voltage backfeed to one source (integrated for single phase).
