Technical performance

Dual power automatic transfer switch according to the power supply voltage state, and the user set the work mode, decide whether to switch from one power supply to another power supply. Its main functions and features are shown in the following table:

Basic structure 

SMGQ1-63Z series dual power supply is composed of two small circuit breakers and their accessories, mechanical interlock transmission mechanism, intelligent controller. Products with three-phase sampling detection function, while installed in the dual-power circuit breaker to maintain the original overload and short circuit protection.

○ Common power indicator: When the normal power supply voltage is normal, this indicator light.

○ Standby power indicator: When the standby power supply voltage is normal, this indicator is on

○ Common power-on indicator: Lights when the switch is in the normal power position; this indicator flashes when the controller is in the return-delay state.

○ Standby power-on indicator: Lights when the switch is in the standby power position; blinks when the controller is in the transition delay state.

○ Automatic / manual switch mode control switch: control switch in the left position for the automatic conversion mode, in the right manual conversion mode.

○ Conversion delay time Set the potentiometer (the delay time between normal power supply and backup power conversion)

○ When the switch is in the normal power-on position, if the standby power supply is normal after the normal power supply fails, the controller starts to time (the time is set by the conversion delay potentiometer). When the timer expires, Switch to the standby power supply; delay time setting a little larger, then you can avoid the instantaneous voltage drop caused by the switching switch (for example, the same power grid in a large motor voltage caused by the temporary reduction of the situation)

○ Return to the delay time adjustment potentiometer (standby power to the power conversion delay time)

○ When the switch is in the standby power-off position, if the normal power supply returns to normal, the controller starts to count (the counting time is set by the return delay potentiometer). When the timer expires, the controller switches the switch to the normal power supply powered by;

Controller Features 

The toggle switch on the controller sets the operating mode of the controller and the rotary potentiometer adjusts the switching delay parameter.

Fire linkage control function: The controller has a set of passive fire signal input terminals. Signal input using optical isolation, anti-interference ability; and with a set of passive feedback signal output terminals can switch the signal in place to return to the fire fighting equipment.

Generator start and stop control function: the controller leaves a set of relay dry node to control the generator start and stop.

On the basis of economic type of voltage monitoring from single-phase to three-phase monitoring.

Terminal and wiring instructions

○ 101,102 three-pole switch commonly used power supply zero line terminal (either one pole can be);

○ 201,202 three-pole switch backup power supply zero line terminal (either one pole can be);

○ 301 ~ 303 Common Power Supply External Status Indicator Signal Output (AC230V 0.5A);

○ 301 - Signal common zero line 302 - Common power supply signal output 303 - Common power supply closing signal output

○ 401 ~ 403 Standby power supply External status indicator signal output (AC230V 0.5A);

○ 401 - Signal common zero line 402 - Standby power signal output 403 - Standby power supply closing signal output

○ 501 ~ 503 Generator start control signal output terminal.

○ When the standby power supply is a self-starting generator set, the user can complete the automatic start generator function by connecting 501 ~ 503 terminals to the generator controller, 501 ~ 503 is a group of 3A passive relay dry nodes, 503 is the relay common 503 and 501 open, if the common power failure and standby power is dead, 503 and 501 closed, while the 503 and 501 closed, 503 and 501 are closed, And 502 disconnect the generator start signal generator after the success of the switch to automatically switch to standby power supply side of the load in the standby power supply process if the common power back to normal, the controller after the return delay control switch to the common Power, circuit breaker closed 503 and 501 after the closure of 3 seconds delay, 503 and 502 disconnect to send a shutdown signal.

○ 601 ~ 604 fire linkage control port; This interface is used to remote control the switch to cut off the power after the fire equipment alarm.

○ 601,602 - fire linkage control signal input, the interface can only be connected to a group of external normally open passive contact (if the fire equipment to send signals for the active signal, you must first transfer through a small relay and then The relay will normally open contact access controller, otherwise it will burn the controller), when the external contact is closed, the controller immediately switch control switch to the sub-gate position to cut off the load power at the same time through the 603 and 604 terminals return signal to the fire control center;

○ 603,604 - internal for a group of normally open relay dry node for fire action return signal purposes; terminal in normal time for the normally open, when a fire signal into the controller and the switch to the sub-switch

The gate positions 603 and 604 are turned on.

Note: When the fire linkage function starts automatically switch will stop working, to make the switch to normal conversion, you must first remove the fire signal and then control panel on the automatic / manual switch after a switch to restore the normal conversion.
