Feature:
1. 2 CONTROL MODES: The transfer switch not only supports automatic mode, but also can be operated through manual buttons, simple to operate.
2. MAIN FUNCTION: When one power supply fails, the switch will automatically connect to the other power supply to ensure normal power supply to the load circuit.
3. HIGH PERFORMANCE: The transfer switch has large load power, fast switching speed, maximum switching speed is less than 2S.
4. MULTIPLE PROTECTION: This changeover supports multiple protection functions, including short circuit, overload, phase loss, and undervoltage protection, very safe and reliable to use.
5. EASY INSTALLATION: This ATS has compact structure, adopts screw installation, can be installed vertically or horizontally.

Working Principle:
The power supply signal of the dual power supply controller and drive mechanism of this series depends on the A phase and N line of the input port of the common switch or standby switch. In the automatic state of the two way power supply, when the incoming phase A and N common switch voltage is normal, regardless of whether the voltage of the public power supply B C and the standby switch a b c and N is normal, the public switch will be closed first, at the same time, the power indicator and the public shutdown indicator light up. When the incoming public switch phase A and line N have no voltage, and the incoming standby switch phase A and line N have normal voltage, whether the voltage of normal switch B and standby switch C is normal or not, the two way power supply is switched to standby, the power indicator and standby close indicator are on. Manual function, no matter whether the public power supply and standby power supply have voltage, can use manual operation mode. In case of manual operation, the manual automatic button shall be placed in the manual operation position. Turn the push handle clockwise to the terminal, the standby power supply air switch R is open, and the public power supply air switch N is closed. When the push handle rotates counterclockwise to the terminal, the standby power supply air switch R is closed and the public power supply air switch N is open.

Note:
1. The maximum ambient temperature shall not exceed 40 celsius , the minimum temperature shall not be lower than ?5 celsius , and the average temperature within 24 hours shall not be higher than 35 celsius .2. The altitude of the installation site should not be higher than 2000m.3. When the maximum temperature reaches 40 celsius , the relative humidity of the installation site should not exceed 50percent . When the temperature is the lowest temperature ?5 celsius , the relative humidity is higher, for example, when the temperature is 25 celsius , the relative humidity is 90percent . Due to temperature changes, special measures should be taken to deal with occasional condensation on the surface of the product.4.
