General

This series of Automatic transfer switch is suitable for AC 50Hz/60Hz, rated working

voltage 230V/400V and below power distribution and control circuit.The current up

to 63A. It is mainly used as the main switch of terminal electrical appliances, and can

also be used to control various types of motors, low-power electrical appliances,

lighting and other places.

Standard:IEC60947-6-1

Features

1.This product adopts modular design,the execution components,transmission mechanism,control circuit is completely independent. So it's easy to replace.

The intelligent Automatic transfer switch is composed of two parts, the controller and the main device, and has a simplified structure in which two sets of circuit

breakers are assembled in a switch shell.

2.The mechanical interlocking device adopts gear drive,which completely eliminates the possibility of closing at the same time.

3.The appearance of product is small. Appearance patent product.

4.The control circuit layout of the controller adopts the separation of working voltage and sampling power supply from MCU control, which overcomes the electromagnetic interference from the hardware structure.

5.The product with complete functions,including starting generator, fire control, fire feedback signal, main power and emergency power closing passive singal output, three phase detection of main power and emergency power.

6.Modular design. Good interchangeability of components. Convenient installation

Control panel description

1.Auto/Manual mode control switch: When the control switch at the right position, it's in automatic mode, and when the control

switch at the left position, it's in manual mode.

2.Mian power indicator: When the main power voltage is normal, this indicator on. It turns off when main power phase is missing,

flashes rapidly at 10Hz when main power overvoltage, and flashes slowly at 2Hz when main power undervoltage.

3.Emergency power indicator: When the emergency power voltage is normal, this indicator on. It turns off when emergency power

phase is missing, flashes rapidly at 10Hz when emergency power overvoltage, and flashes slowly at 2Hz when emergency power

undervoltage.

4.Emergency on indicator: When the emergency circuit breaker is closed, this indicator on. Flashes slowly at 2Hz when the emergency

circuit breaker trips.

5.Mian on indicator: When the main circuit breaker is closed, this indicator on. Flashes slowly at 2Hz when the main circuit breaker trips.

6.Terminal 1,2 and 3 is start generator output terminal: When the main power supply is normal, port 3 and 2 will turn off. And port

3and 1 will turn on. When the main power supply abnormal, port 3 and 2 will turn on. And port 3 and 1 will turn off. It is

recommended to connect normally closed contacts port 3 and port 2.

7.Terminal 4-5: Main power on state passive output port.

8.Terminal 6-7: Emergency power on state passive output port.

9.Terminal 8-9: Fire feedback: It is a passive output port. When the fire signal is connected and the product is powered off

successfully, this port is closed.

10.Terminal 10-11Fire input: Passive input signal, short-circuit this port, switch transfer to power off position. And the main power on

indicator light and the emergency power on indicator light flashes alternately. If you need to remove the fire status, you can

manually flip the "manual/automatic" switch, and turn the switch to the "automatic" state after completion.

Notice:

If the Mian on or Emergency on indicator flashes. At this time, it is necessary to manually check and confirm that the load side is

normal, and then toggle the Manual/Auto switch to release the fault signal, and in manual mode state rotate the operation handle to
