1. Summary
Along with the development of the society, the people have exigent request to the power supply. Our company according to the user’s actual need and developed intellectualized dual power ATS. This product strongly anti-jamming, works stable and reliable, not only switch between two groups power, but also examine to two groups three-phase four voltages. When any phase voltage exceptionally, can automatically switch the unusual power to the normal power or sends out alarm.
2. Suited area
The ATS suited to the double power supply system of AC50/60Hz,rated voltage under 600V,rated current under 2000A. It can realize between the prime power (N) and the standby power (R) automatic switch (also may establish for manual switch) .This product with communication serial port, may realize the long-distance control, causes the user to realize nobody duty transformer substation. This product is suitable to the important place which does not permit the power cut low voltage switch cabinet.
3. Conforms to the standard
3.1 IEC60947-1 General rules;
3.2 IEC60947-61(1998)《ATS》;
3.3 IEC947.2;
3.4 GB14048.11-2002;
4. Product Model

5. Applicable area
5.1 The surrounding temperature is not higher than +40℃ or lower than -10℃
5.2 Installation place: The altitude above sea level should not be higher than 2000m.
5.3 Contaminated grade
Grade:3. Have any explosively surrounding, any corrosive metal and ruinous gas, liquid, electric dust which may destroy insulation.
5.4 atmosphere condition: The air relative humidity does not surpass 50% when the highest temperature is +40℃,under the low temperature not to allow to have a higher relative humidity. The wettest month average temperature does not surpass for +25℃, this month biggest average relative humidity not to surpass 90%.
5.5 If the condition mentioned above can’t be satisfied, please discuss with manufacturer.
6. Structure and function
6.1 Structure
6.1.1 The ATS is made up of controller and equipment, between the separate units should be connected with leased line, the line can not surpass 2 m.
6.1.2 The equipment is made up of special positive,contrary electro-motor, breaker, fire protection breaker,mechanical interlocking,the aviation inserts,connection ports and so on. All of these parts are installed in a plate
6.1.3 This intelligent system ( working voltage 400VAC,50/60HZ) with mechanical electricity dual interlock protection, provided the safe、reliable guarantee for you.
6.2 function
The auto controller inspects the two voltages at the same time. When the voltage 115% higher than rated voltage, then judging it over voltage; when it 60%-80% lower than rated voltage, then judging it owe voltage. The PC will judge the results and dispose it, send out shut break、off break、 generate electricity、uninstall、alarm、etc. The above results display on control panel which may connect with PC through serial port in order to user to find out the reason. The intelligent controller can divide into three types: Auto Gen/Auto Main suited between electricity network; Auto Gen/Auto Manual suited between electricity network; Auto Gen/Auto Main suited between electricity networks and generate electricity.
6.2.1 Auto Gen/Auto Main (R) suited between electricity networks
The electrify initialization default the supplier is prime power, when the voltage of prime power (N) occurs unconventionality, after off break and time delay ,prime power (N) automatic changes to zero position, after again shut break and time delay ,the automatic changes to standby power (R), the delay time may establish 0-30 second
6.2.2 Auto Gen/Auto Manual suited between electricity networks
Controller inspects and changes the prime power and standby power. The initialization default the supplier is prime power, when the voltage of prime power (N) occurs unconventionality(Any phase of supply voltage occurs over voltage, owe voltage, lacks of phase), after off break and time delay ,prime power (N) automatic changes to zero position, after again shut break and time delay ,the automatic changes to standby power (R),
6.2.3 Electricity network and generate electricity.

（Incorporate ATS）

（Fissionable ATS）

The controller prime power(N) and the standby power(R) carry on the examination, because the standby power(R) supplies the generator, the prime power’s voltage is normal when does not generate. When the voltage is 60%-85% of the rated power, the intelligence system can give an instruction to the generator (a group of closing ports) .After time delay automatic changes to standby power. After the voltage normal again, the intelligent system separates automatically from the standby power after the time delay, turns to the prime power source.

8. Install and wiring diagram

Note: This wiring diagram suits three-phase four, when selects three-phase three wires, the commonly used power source zero curve (NN) receives the tag board N1 foot, the emergency power supply zero curve (RN) receives the tag board N2 foot
Outside the HD commonly used power source meets the condition to instruct AC220V/1A (user supplies for oneself); Outside the TD emergency power supply meets the condition to instruct AC220V/1A (user supplies for oneself);
