SQ5 automatic transfer switch (PC level ATS), switch, and logic control are set as an organic whole, without an additional controller, realizing mechanical and electrical integration of automatic rollover over In switch, a detecting voltage, frequency, communication interface, electrical, machine Machinery interlock functions, which can realize the automatic emergency manual control, electric remote, Operation is made up of logic control panel with all sorts of logic commands to manage the motor, gearbox Operation, the motor often switch spring energy storage, the instantaneous release Speed, fast through breaking circuit breaker or circuit transformation, through clearly Visible to realize security isolation, greatly improved the electrical properties of the machinery Performance.
SQ5 series automatic change-over switch is mainly used for AC 50 Hz, rated voltage 380 V, the control of rated voltage 220 V, rated current, 16-3200 A- a distribution or electric Master the machine in the network or each equipment system and the mains switch and power generation group The load switch.
At the same time, it can also be used for infrequent and connected with the breaker circuit wiring the isolation.
Products such as high-rise buildings are widely used in firefighting, hospitals, and Banks. They are important places for power supply of power to lose, power distribution systems, and automation systems.

(7) Control type: I Type; II Type; III Type
Main – standby: power supply, since the self-restoring.
I type automatic conversion control automatically, the complex of two-way power supply: only commonly used Power, standby power supply (widely used double power source automatic power loss of pressure or lack of phase transformation Use, return to normal commonly used power, does not allow two way) at the same time;
II types the city power – city power, main preparation or for each alternative (i.e. the cast or since Since since couldn’t answer), two-way power phase lack of phase, under Voltage detection;
III type mains – oil machine, since the vote since the compound, two-way power supply three-phase lack of phase, Under voltage, oil machine frequency detection;
Note: fission, needs to order an additional controller.
