It supports currents from 16A to 800A and offers multiple control modes (Basic, Fire, Intelligent) for automatic, self-recovery, or emergency power switching. Renowned for its large current capacity, simple structure, and low failure rate, it guarantees reliable performance and easy maintenance for essential power systems.

Product Details

Product Descriprion

The EATS-GA is a high-quality, isolated automatic transfer switch (ATS) designed for reliable power supply management in critical environments such as hospitals, data centers, and industrial plants. As a PC-class product, it boasts a robust design that integrates a built-in relay and an external controller into a compact form factor. Its key advantages include a high current rating (from 16A up to 800A), simple structure, ATS integration, low failure rate, and ease of maintenance.

The switch offers versatile control modes to suit various application needs. These include: Basic Type for self-recovery with priority on the main power source; Fire Type for emergency power cutoff with a 24V strong interlock signal; and Intelligent Type with a split external controller for comprehensive protection against over/under voltage and phase loss. It ensures automatic transfer from a failing main source to a backup generator and seamless return once main power is restored. The product features a clear three-state indicator ("I", "0", "II") and manual operation handle for safe maintenance. Comprehensive wiring diagrams and detailed debugging instructions for automatic and fire-fighting modes are provided to ensure correct installation and operation. Professional installation is recommended for optimal safety and performance.

Technical Specification

Dual power automatic transfer switch is a new type of automatic transfer switch that integrates switch and logic control in one and truly realizes mechatronics integration. It is suitable for rated insulation voltage to 1000V,rated frequency 50Hz,rated voltage to 400V,and agreed heating current to 800A power distribution equipment of industrial enterprises. The automatic conversion of the main power supply and the standby power supply used as a power supply system or the automatic conversion pole of two load devices are safely isolated. Widely used in hospitals,shopping malls,banks,high-rise buildings,coal mines,telecommunications,iron ore,highways,airports,industrial assembly lines and military facilities do not allow power outage important occasions.

Switch Control Type and Corresponding Function (Automatic Switching)

1). Basic type:self-recovery,I route priority,with starting generator signal;

2). Fire type:self-recovery,I priority,DC24Vstrong cutting,with start generator signal;

3). Intelligent type:split external wiring intelligent controller,with over-voltage,undervoltage,lack of phase,broken equal detection protection,can set I priority,II priority,no priority (self-throw not self-recovery)automatic fire 24Vdouble,fire broken line double,fire feedback signal,start generator signal.

4). Self-recovery:when the usual power is off (or out of phase),the switch automatically switches to the standby power supply,and when the usual power supply returns to normal,the switch automatically returns to the usual power supply.

5).Fire double:In an emergency or equipment maintenance,start the fire power supply (constant voltage),the switch automatically switches to"0"to cut off the power:

6). With generator (oil engine):when the mains power supply is off(or out of phase),it sends a signal to start the oil engine,so that the oil engine automatically starts,such as normal power generation,the switch will automatically convert to the power supply and when the mains power supply returns to normal,the double power switch will automatically return to the mains power supply,and the generator signal will automatically turn of and start,the generator will stop generating power.

Switch Structure Description

Electrical button switch: control switch internal control line power supply, button switch open, switch to achieve automatic conversion;

Operating handle: When manually operating with the operating handle, the button switch must be turned off first;

Indicator: Indicates the position of the three states (I, O, and II) of the arrow, indicating that the arrow pointing to "I" indicates that the switch I is on, indicating that the arrow pointing to "II" indicates that the switch II is on, indicating that the arrow pointing to "O" indicates that the switch I and the switch II are off (fire fighting).

Switch Instruction

1、Non-professionals, do not install; Do not open it without our permission to avoid damage.

2、Please read this manual carefully before installation to avoid improper use.

3、The rated voltage of the internal control power supply of the switch is 220V, from the C1.N1 of the common power supply and the C2.N2 of the standby power supply, within the rated control voltage range of 85%-110%, the switch can work normally.

4、The switch into the wire end power supply should have overvoltage protection, so as not to damage the internal circuit board control motor.

5、The switch outlet power supply should have short-circuit protection, so as not to short-circuit the current is too large and burn the switch body.

6、When using the installation, please turn off the electric button switch, and switch to: "0".

7、When wiring the switch, please measure and distinguish the A.B.C.N of the power input line and connect it to the corresponding pole of the switch.

8、Before power use, please measure again whether the C.N voltage is within the rated control voltage range of 85%-110%, and then turn on the electrical button switch and formally put into work.

Switch Connection Method

Switch Debugging Instruction

1、Use the operating handle, repeatedly operate the switch three times, the switch should operate flexibly

2、Automatic debugging: according to the wiring diagram to connect the corresponding line, confirm and then open the button switch and switch on the dual power supply, the switch should be switched to "I" : then disconnect the common power supply, the switch should be switched to "II" : then switch on the common power supply, the switch should return to "I".

3、Fire debugging: in any case, start the fire power button, the switch should be turned to "0" file

4、Detection signal indicator: normal/standby power on/off, switch "I/I1" when the signal indicator should be given the corresponding indication.

5、After debugging, please turn off the power first, and then use the handle to switch to "0".
