STQ1 series automatic transfer switch
Applicable range
STQ1 series automatic transfer switch (hereinafter referred to as ATS) is made up of two GTMI series circuit breakers with high breaking capacity and Sahmataer ATS controller, suitable for CAT-A loads and some CAT-B loads in important fields where the power failure is unallowable such as the apply to rated voltage 400V 50Hz rated current 800A high-rise building, hospital, shopping mall, bank, fire control, chemical engineering, metallurgy, military facilities, used to finish automatic transfer of power at the dual-circuit power system, and to guarantee the reliability of user's power supply.
The product is in accordance with the GB/T14048.11.11-2002 and IEC60947-6-1 (1998) Automatic Transfer Switching Equipment and so on.

Model
Note: The integrated type refers to that the controller and the body are assembled in the same bottom plate.
The separated type refers to that the controller is separated from the body, and they are connected with the connector and cable.
Normal working conditions
Ambient temperature:
Upper limited value is not higher than +40℃;
Lower limited value is not lower than -5℃;
The average value shall not exceed +35℃ within 24h;
Installation site:
The altitude of installation site shall not exceed 2,000m.
Air conditions: Air relative humidity shall not exceed 50% at the max temperature +40℃; the higher relative humidity is allowable at the lower temperature, the monthly average min temperature shall be +25℃ in the dampest month, meanwhile, in this dampest month, the monthly average max relative humidity shall be 90%, in addition, the product surface condensation resulted from the change of temperature shall be taken into the consideration.
Applicable environment
ATS shall be installed in the dry environment free of the conductive dust, corrosive, explosive or flammable gas, it shall avoid the rain and water entrance and can't be impacted or vibrated, its vertical inclination of installation shall not exceed 5 degrees, the external magnetic of ATS installation site shall not be 5 times as high as the earth magnetic field in all directions.
Performance features
STQ1 series automatic transfer switch has the perfect test and protection functions. It employs the high-speed embedded chip microcomputer as the main control chip, to monitor the power supply at the real time and ensure the reliable operation of power supply system.
1.Mechanical interlock and electric interlock dual-protection function, which can prevent two circuit breakers closing at the same time;
2.Six control and operation methods including "manual control", "self-input self-reset", "normal power supply", "reserve power supply", "re-trip under power failure" and "self-input non-self-reset";
3.Protections against under voltage, over voltage and phase lack, which can prevent the fault power being transmitted to the load;
4.Alarm or indication of power supply failure and circuit breaker tripping.
5.Prevention of two re-closing operations, that is, the automatic closing operation can't be performed again after the circuit breaker performs the automatic closing (tripping) operation and following troubles happen: load side short circuit, overload, etc..
6.The operation parameters (under voltage value, over voltage value, opening delay value, closing delay value) may be set and adjustable, LCD displays the two-circuit phase voltage at the same time; the full Chinese menu operation takes the convenience for user's real-time search.
7.It has the fire-control interface, in case of emergency, only the fire-control power supply of DC24V (the control voltage is selected by customer) is connected, the controller can output the control contact to cut off the relevant power supplies at once.
8.It has the RS485 and RS232C serial communication interfaces and employs the MODEBUS communication protocol.
Main technical parameters
Electric class: CB (that is, the main contact of circuit breaker can make and break the short-circuit current and the over-current release is equipped);
Usage category: AC-33B (typical application: motor load, resistor and incandescent lamp load of 30% below);
Rated working voltage: linear voltage~400VRated frequency: 50Hz;
Under-voltage protection setting range: 150V~180V adjustable, difference 1V, the default value 150V;
Under voltage recovery normal value: under-voltage value +25V;
Over-voltage protection setting range: 240V~280V adjustable, difference 1V, the default value 280V;
Over-voltage recovery normal value: over-voltage value -10V;
Opening delay time: 1.2~60s adjustable, difference 1s, default value 1.2s (1.2s represents 12, and 60s represents 600);
Closing delay time: 1.2~60s adjustable, difference 1s, default value 1.2s (1.2s represents 12, and 60s represents 600);
Startup delay time of generator: 10s;
Display accuracy of voltmeter: 2.5;
Note: The under-voltage value, over-voltage value as well as supply voltage of each phase refer to the voltage between the phase and neutral wire.
