Introduction of Static Transfer Switch:
STS(Static Transfer Switch) is a kind of  automatic switching system for choosing one power source from two. At normal working status, load will be connected continuously to main power source when the main power source is within normal voltage range. When the main power source is failed, load will be automatically switched to the backup power source. When the main power source restored, load will be automatically switched back to main power source. ( Priority of Main Power Source)

STS( Static Transfer Switch) adopt switching method of Break before Make to realize uninterruptible switching between different input power source for powering single load with double bus, for example:
* Non-parallel N+1 redundance UPS system;
* Different capacities of N+1 redundance UPS system;
* Different models of N+1 redundance UPS system;

Characteristics of Static Transfer Switch:
This serial static transfer switch consists of intelligent control board, high speed SCR, breakers. It adopts transfer technology of “Break for Make” , the transfer time is less than 8ms, it can supply continuous power to load, and ensure the security in different transfer. Meanwhile, this product has other features below:

More perfect in protection:
■ Over and low voltage protection: When AC input voltage is lower or higher, this product will transfer to another power source
■ Intelligent detective: When one power source fails(including manual transfer), this product can transfer to another power source automatically, avoid the danger of manual transfer or power interrupt
■ Overload protection(Option): When the load is more than 150%, this device will shut off automatically, and gets alarm, then it will start automatically after 10 minutes

Intelligent Alarm:
■ When mains power fails, this product can alarm automatically, and be silent after 90 seconds
■ When mains power is out of input range, this product can alarm automatically, and be silent after 90 seconds

Manual Transfer function
■ When two power source is normal, customer can transfer to each power source manually
■ When one power source fails or out of range, this device can forbid manual and automatic transfer function

Automatically timed transfer(Option)
Customer can configure the running time of each power source, and transfer to another power source after the setting time, ensure the aging balance of two power sources.
