OPQ2 Dual power automatic transfer switch 

Product Description

OPQ2M series automatic power switch mainly consists of power conversion actuator, circuit breaker and controller.This double power switch has automatic, manual, power indication, common closing indication, standby closing indication, etc.The switch is characterized by small size, long life, low power consumption, light weight, stable operation and convenient operation

lnstallation and usage

When wiring is installed, common power N shall be connected to common power execution circuit breaker QN, and standby power R shall be connected to standby power execution circuit breaker QR.When QN and QR are four-level circuit breakers, the wiring mode is according to the wiring diagram, where ON and QR's 1,3,5 are three-phase (A,B,C) incoming terminal, 2,4, 6 are three-phase outgoing terminal, 7 is zero line (N) incoming terminal, 8 is zero line outgoing terminal.If a three-pole circuit breaker is selected, the zero line (NN) of the commonly used power supply N and the zero line (NR) of the standby power supply R must be connected to the dedicated three-pole zero line terminal KG respectively.See wiring diagram for specific protection.The working power of the automatic controller of the double power switch is taken from the incoming terminal A phase and zero line N of the circuit breaker QN and QR. During the installation and wiring process of the automatic power switch, do not forget to connect, break or short circuit the sampling signal line of the original controller in the incoming terminal of the circuit breaker, or it will not work normally.

Using the operating

Choose automatic working state, the default boot common switch, manual operation, manual, automatic button device in manual operation shall be, when push the handle clockwise to the terminal, commonly used QN power execution circuit breaker closing operation, standby power execution circuit breaker QR break-brake: when push the handle clockwise to the terminal, standby power execution circuit breaker QR closing: commonly used circuit breaker QN points brake power execution.

Intelligent controller function

OPQ2 intelligent double power switch.The controller has keyboard bit input and (LCD) LCD display, can be used for common power (N)

And standby power supply (R) three phase four wire synchronous detection: the loss of pressure, power outages, phase detection function, less than 80% rated voltage is worth the following sentences is loss of pressure, standby power supply (R) fault alarm, microcomputer to deal with the result of the test, then issue the corresponding instruction, the results also showed on the (LCD), to give the user a good man-machine dialogue interface, computer detecting abnormal data delay into two points, the delay time (0-30 s) switch to normal power supply.

Structure and function

Switching operation has three state power users to choose: common power supply (N), standby power supply (R), standby power supply (R), common power supply (N), common power supply (N), standby power supply (R)

Auto switch over and self recover(mains supply--mains supply)

When the normal power supply is abnormal (any phase overvoltage, undervoltage, or phase break), it will be automatically switched to the standby power supply (R) after the delay. The delay time can be set as 0-30s and 3s when leaving the factory.When the common power supply returns to normal, it will automatically switch to the common power supply (N).When the controller detects the fire command, the controller issues the command to switch on and off.When the alarm system is turned on, the controller will display the alarm, and when the fire command or common power supply is detected to be abnormal, the alarm will sound "dudu".

Auto switch over without self recover(mains supply--mains supply)

Initial default boot automatically, commonly used (manual, double points) power supply, when the common power supply is abnormal (Ren Yixiang overvoltage, undervoltage, or pressure), after the delay switch to standby power (R) power supply, delay time can be set to 0 to 30 s, factory set to 3 s, commonly used power supply back to normal after, is not automatically switch to the common power supply (N) power supply, when the common power supply is abnormal (Ren Yixiang overvoltage, undervoltage, loss of pressure or phase), after a delay can automatically switch to the common power supply (N) power supply: when the controller to detect fire instructions, the controller issued instructions to switch the double points;When the alarm system is turned on, the controller will display the alarm, and when the fire command or the standby power supply is detected to be abnormal, the alarm will sound "dudu"

Auto switch over and self recover(mains supply--electric supply)

Controller for common power supply (N) and power generation power supply (R), when the common power supply (N) abnormal, sends out a system for generator instruction (passive normally open contacts) start the generator set, after the common power supply back to normal (N), intelligent system by the time delay, automatically returns to the common power supply (N) power supply, generator set artificial closed
