The TST200 Static Transfer Switch is a hot pluggable single-phase transfer device, providing
automatic switching between two independent AC power sources. It could achieve very fast
switch without interrupting power and it is suitable for important IT equipment which can not
afford power disruption and ATS can not satisfy. Meantime, it integrated a maintenance bypass
inside which could achieve automatic switch to maintenance bypass (MTS) incase of STS
maintenance.
