Static transfer switch
220 VAC, 20 - 100 A | TST100 series
TBB POWER
Single-phase, 220VAC, 20-100A
The 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.
Features:
- Transfer time less than 4ms when input power are synchronization and transfer time is less than 10ms in case of input non-synchronization
- Intelligent monitor, diagnostics and alarming
- Protection and alarm against High Voltage, Low Voltage, Power Failure, overload and shortcut.
- Overload protection: STS shutdown in case of 150% overload and will reconnect after 10s
- Shortcut protection: in case of output shortcut, system would cutout output offering protection for input power.
- User can set up either input as main and the other will be standby automatically
- Support manual select
- In case of STS fail, the system will choose one input source as fix source, to ensure uninterruptible power supply
- RS232 or RS485 communication
- Structure : 19"2U
