Supply LEATS1A automatic transfer switch 18879983199

The intelligent dual power automatic transfer switch (hereinafter referred to as the switch) consists of a circuit breaker and an intelligent controller. It takes the latest microcomputer control system as its core, has electromagnetic compatibility design, strong anti-interference performance, stable and reliable long-term continuous operation, and is equipped with a large-screen backlight display to form a good human-computer dialogue interface for users, with easy and high-level operation and warning. Intelligent, it is an ideal new type of electromechanical integrated dual power automatic switch. For details, please consult
The product complies with the standards/Low-voltage switchgear and control equipment, Part 2, Multi-function Electrical Appliances, Part 3, Automatic Transfer Switch Electrical Appliances".
Scope of application
This switch is suitable for dual power supply switches below constant voltage and rated current. It can realize automatic or manual switching between common power supply and backup power supply. (The main and backup power sources can be the power grid, starter generator set, battery, etc. The main and backup power sources are determined by the user). This enables customers using dual power supplies to be unattended. This switch is suitable for special or first-level load users specified by the state, such as high-rise buildings, postal and telecommunications, coal mines and ships, industrial assembly lines, medical and health care, military facilities, airports, fire protection, metallurgy, chemical industry, textile, petroleum and other important places that do not allow power outages. place.
Normal working conditions
▲When the ambient air temperature is ~+℃, the average value does not exceed +℃
▲When the maximum temperature is +℃, the relative humidity does not exceed that. Higher relative humidity is allowed at low temperatures. The humidity is, for example, +℃, but it should be considered that condensation may occur due to temperature changes.
▲The altitude of the installation site does not exceed. Categories are classes. The slope is no greater than . The pollution level is level 1.
▲If the above conditions cannot be met, you should negotiate with the manufacturer when ordering. When this switch is used in mining, offshore, petroleum and nuclear power plants, a separate technical agreement should be signed.

Structural features and functions▲ The type switch switching drive adopts a single motor drive, with a simple structure, reliable and smooth switching, no noise, and small impact force. The operator's drive motor only passes current at the moment of switching. There is no need to provide working current for steady-state operation, which saves significant energy. There is no temperature rise, junction welding or motor burnout. The switch is equipped with mechanical interlock protection to ensure that the main and backup power supplies will not be turned on at the same time, ensuring that the common and backup power supplies work reliably and do not interfere with each other. The switch can be switched with load, and the handle can be used for manual switching in an emergency. The electrical or mechanical closing indication control power of the switch is drawn from the main AC power supply (no additional control current is required).
▲The intelligent controller also provides multiple functions such as voltage loss, phase failure control, undervoltage, delay control, generator control, fire reset, feedback signal, etc., and has strong anti-interference ability and self-turning, self-restoring, and self-recovery functions. There are three working modes: common power supply combined, backup power supply divided into common power supply points, backup power supply combined with common power supply points. The backup power supply is divided into three stable working states
▲Easy to install, the control loop adopts connection Plug-in terminal connection
▲A special handle can be used for manual conversion in manual mode
