Product Overview
Statis transfer switches (STS) supply power to a range of equipment from two independent power sources. STS automatically transfers power to a stable alternate source under normal operating conditions to protect the load from even a few power frequency cycle interruption times, or from any surges or sags in the prime power source.
PROTEK
STS Series, Static Transfer Switch 50 to 1000A
Our STS is an industrial electrical device that features superfast static switches (SCRs) to transfer instantaneously between two power sources. One power source will be the default source while the other will act as a standby. Furthermore, the STS can also be specially customized for 3 phase, single phase, and various voltage input from AC power sources.
