Product details
Black small STS static transfer switch 8KVA (32A) rated output power
The static transfer switch is a dual-input transfer switch, usually one channel is connected, the other channel is disconnected, and the load is powered by one AC input. When one power supply fails, the STS automatically disconnects the original one, and turns on the other one that was disconnected, converting the load to the other power supply without interruption.
This model is designed for a 19-inch cabinet; it can also be installed on the front panel or in the center of the cabinet, depending on the location and location of the fixed edge.
The technical characteristics of our company's STS static transfer switch:
◆Adopt full digital control, strong anti-interference ability and fast operation speed.
◆Switching time <5ms, high reliability; automatic and manual switching.
◆Strong overload capacity, can withstand full load boot.
◆With input over-voltage, under-voltage, output over-voltage, under-voltage, over-temperature, overload and other protection functions.
◆The front panel is equipped with a monitoring screen (no under 10KVA), and the status information is clear at a glance.
