Generator Set Automatic Transfer Switch (ATS)

Overviews

Suitable for AC 660V and below, rated frequency 50 Hz, whether it is normal or not. As long as within the technical parameters of the switch, all can be guaranteed safely and reliably operate in the corresponding voltage grades of occasions.

1.2 Service conditions

1.2.1 ambient air temperature

A) the highest temperature ≤+ 60°C

B) the lowest temperature ≥- 20°C

C) the highest average temperature ≤+ 60°C

D) the ambient air temperature is higher than + 60°C or below -20°C the user should negotiate with the manufacturer.

E) environmental temperature >60°C ≤80°C should reduce capacity selection (off about 20%);

1.2.2 atmospheric temperature

When the highest temperature +60°C relative humidity≤50%. Moist air on the sea will influence capability when the max monthly RH is 90%.

1.2.3 installation elevation

The installation elevation ≤2000 m. When used in higher altitudes, theuser should check with the manufacturer as decrease of electric strength and cooling action.

1.2.4 pollution levels

Class of pollution: class 3.

1.2.5 installation category

Installation category as class IV.

1.2.6 installation tilt

ATSE is a rack fixed installation, installation tilt ≤+22.5.

1.2.7 use categories: AC - 33 ib

I.3 Product features

1.3. 1 installation performance is good

1.3. 2 with double row composite contact, horizontal pull-out mechanism micromotor energy storage and microelectronic control technology, the basically zero arcing (no arc clute)

1.3. 3 use reliable mechanical interlock and electric interlock, ensure higher Security

1.3. 4 using a zero technology, an emergency can be forced to zero at the same time to cut off the two power supplies

1.3. 5 has obvious on/off position indicator, padlock, and other functions. Insulate the power and the load reliably. With high reliabibity and more than 10000 times using life.

1.3. 6 good electromagnetic compatibility, strong anti-interference ability, no interference

1.3. 7 high automaticity

1.3. 8 switch has multiple input/output interface, easy to implement remote PLC control and system automation. Switch can work without any other controller.

1.3. 9 beautiful shape, small volume, light weight. The logic control board can control operation of the motor (inside the switch) using different logic to make sure the switch on it's position.

1.3 Features

ATSE  series as the main, dual power automatic transfer switch is mainly used in the first class load and second class load (which need back-up power) confirmed by the nati- onal regulations , suitable for highrise buildings, post and telecommunications, coal and shipping, industrial assembly line, health care, mditary facilities, etc. The main standby power can be grid, generator, battery, etc. The main standby power can be customized by users. Transfer time of the main switch body is not more than 1s. Users can make special delay when necessary. The main power takes priority over the main standby power when supply electricity together.

2.1 The main technical parameters

Meet IEC947-6-1 / GB 14048. 11

The supply voltage - Standard: AC 220V, customizable AC 110V, AC 380V, DC 12V DC 24V

2.2 Switch structure

2.3 Terminal function

1, Electric lock: control the power of control circuit inside the switch. When the electric lock turned on, the switch can be remotely operated, otherwise the switch will be hand operation.

2, Operation handle: electric lock must be closed when using operation handle.

3, Mechanical padlock: Before you overhaul, you must turn off the electric lock, use the operating handle to force the switch to “0” position, pull the mechanical padlock and lock it.

4, Position indicator: indicate working status of the switch (I, 0, II).

5, The control voltage: AC220V.

6, The switch body: part in the front is line I, connect with the normal power. Part at the back is line II, connect with the standby power.

2.5 Installation size

SYK series dual power automatic transfer switch is suitable for power system of insulation volt 750V, rated frequency 50HZ/60HZ, rated working volt 440V and below, rated current 20A~3200A. Widely used in high-rise buildings, telecom- munications, industrial and mining, shipping, power stations, hospitals, banks and other places need uninterrupted power supply.

SYK series ATS let the power supply system transfer between two power in emergency, the minimum conversion time is 0.3s to make sure the main load (emergency lighting, emergency staircase, fire-fighting system, etc) working continuously and reliably.

Generator connection mode

Note: 101-106 for switching power supply input and output terminals

201-206 for switch control terminals

301-306 for the switch status indication terminal

1 Qf primarily circuit (mains) protection switch alarm contacts

1 Kt for power on delay (0-180s), 2kt for power off delay (0-180s)

3.1 switch wiring instructions (see 2.2 switch structure)

3.1.1 switch from left to right, I copper busbar connect with A, B, C, N of Commonly used power (in the front) and II connect with standby power (at the back).

3.1.2 control power is taken from C of commonly used power and N of standby Power

3.1.3. control power AC220V of line I connect to terminal 102-103, control power AC220V of line II connect to terminal 104-105, 102 is fire wire for commonly used power and 104 is fire wire for standby power.

3.1.4 terminal 101, 106, just as a light control power, of which 106 is fire wire. Note that 101, 106 can not connected to any other lines.

3.1.5 When the top (bottom) of line I inset wire, A, B, C, N at the bottom (top) use conection of copper busbar to output it. And line II use wires.
