The single-phase STS static switch is specially design for the important
equipment that cannot be powered off. It is a non-contact electronic switch
device that realizes two-way AC power supply backup and fast switching to
each other. It can be switched automatically or manually, and the switching
time less than 4mS to ensure the supply continue.Always used it in parallel model solution.
Full digital control, strong anti-jamming capability and high computerization speed;
The transfer time is ≤5ms; high reliability; manual and automatic switches are both available;
Strong overload capacity; can be started under the full load
Having input and output over-voltage and under-voltage, over-temperature and overload protection functions, etc.;
The front panel is equipped with a control panel (NA for the one less than 10K), so the information about the condition is obvious.
