STS fast static transfer switch for dual ac power

Fast static transfer switch for dual ac power TST100 Static Transfer Switch is single-phase transfer device, providing automatic switching between two independent AC power sources. It combined the STS and MTS into one unit which greatly increased the system reliability along reducing the transfer time to less than 4ms. It was suitable for important IT equipment which can not afford power disruption and ATS can not satisfy. Transfer time less than 4ms when input power are synchronizationand transfer time is less than 10ms in case ofinputnon-synchronization.
