PТQ3 series Dual Power Automatic Transfer Switch
overview
PTQ3 series is a pc-level dual-power automatic switching switch, featuring novel shape, beautiful appearance, small volume, complete functions, LCD screen and easy operation. It is widely used in automatic switching of power supply for primary and secondary important loads, fire fighting loads, emergency lighting and infrastructure in buildings. The product is used in power distribution systems with rated voltage up to AC400V/50Hz and rated current up to 1600A. At the same time, it can also be used as a product with infrequent connection and disconnection. Capable of switching on and carrying short-circuit current; The ability to switch power under full load and strong anti-interference ability. It has two or three stable working positions, a variety of flexible control functions and energy-saving, noiseless, reliable working and other characteristics.
Scope of application
PTQ3 series automatic switching switches are mainly used for load switching between main and standby power supply or each other in power distribution or motor network with AC 50Hz, rated working voltage 400V and rated current 16A to 3200A as well as power supply and generator sets. At the same time can be used for infrequent on and off circuit isolation.
Products are widely used in fire, hospitals, Banks, high-rise buildings and other important power supply sites are not allowed to power off power transmission, distribution systems and automation systems.
The product conforms to GB/T 14048.11 standard.

The working conditions
● Ambient air temperature: -5℃~+40℃, and the average value of 24h does not exceed +35℃;
● Atmospheric conditions: atmospheric relative humidity does not exceed 50% at the highest ambient temperature +40 ° C, and higher humidity can be obtained at lower temperatures. When the lowest average monthly temperature +25 ° C is the wettest month, the average maximum relative humidity of the month is 90%, and condensation on the surface due to temperature changes is taken into account.
● Elevation: the elevation of the installation site shall not exceed 2000m;
● Pollution level: the environmental pollution level at the installation site is level 3.

Performance and Characteristics
● Double row compound contact \ horizontal pull \ micromotor prestorage and microelectronic control technology, basically achieve zero flashover;
● Reliable mechanical interlock and electrical interlock are adopted, and independent load isolation switch is adopted for execution components to ensure safe and reliable use;
● The zero-crossing technology is adopted, which can be forced to set zero in case of emergency (cut off two power lines at the same time) to meet the needs of fire linkage;
● The switch of load isolation switch is driven by a single motor, which makes the switch reliable and stable, with no noise and small impact force.
● The operator drives the motor to pass the current only at the moment of load isolation switch switching, and the steady-state work does not need to provide the working current, so the energy saving is significant
● The execution load isolation switch is equipped with a mechanical interlock device to ensure the reliable operation of common and standby power sources without interference;
● With obvious on/off position indication, padlock and other functions, reliably realize the isolation between power supply and load;
● Good safety performance, high degree of automation, high reliability, service life of more than 8000 times;
● Mechanical and electrical integration design, switch conversion accurate, flexible, smooth, the use of international advanced logic control technology, strong anti-interference ability, no external interference;
● It has main power supply and backup power supply; The main power supply is divided and the standby power supply is closed; The main and backup power supply are disconnected for three kinds of stable work (o-!);
● Easy to install, the control loop is connected with plug-type terminals;
● Four kinds of operation functions: emergency manual operation, electric remote control operation, automatic control state emergency disconnect operation, automatic control operation.
