Static Transfer Switches

Uninterruptible power supplies (UPS) are a vital part of critical electrical infrastructure, however, how do you maintain electrical power and keep your critical systems running in the unlikely event of a UPS output failure?

Cetronic Power supply static transfer switches (STS) – also referred to as a UPS transfer switch - to seamlessly switch/transfer power from one supply source to another.

What are Static Transfer Switches?

Static transfer switches provide ultra-fast switching between synchronised input power supplies, providing you with uninterrupted power for your mission critical load. Meaning you don’t need to shut the system down to carry out maintenance work.

Single Phase Static Transfer Switches

Master Switch STS 32A - 120A

The Master Switch STS ensures transfer time between the two single phase power sources is less that a quarter of a cycle in the event of a failure of the primary power source. All models are equipped with a manual bypass and a hot swap function.


Multi Switch ATS 16A

The Multi Switch ATS provides output power via 8 x 10A and 1 x 16A IEC socket. The power is derived from one of two input power sources. If the primary power source fails, the Multi Switch ATS will automatically transfer the load to the second power source.


Multi Switch 16A

The Multi-Switch provides electrical distribution and remote management for up to eight output power sockets. Multi-Switch can connect each socket (load not greater than 3A each) to either of the two power sources (A or B). Load demand is shown on the LCD.


Three Phase Static Transfer Switches

Master Switch STS 100A - 600A

The Master Switch STS is a 3 phase (3 or 4 pole) static transfer switch commonly used within power continuity applications to improve and enhance resilience. The system can be used in conjunction with UPS groups or as separate standalone devices.
