Series Automatic Transfer Switch
//
Product Overview
The automatic transfer switch is an automatic transfer switch that integrates switching and logic control without the need for an external controller. It truly realizes electromechanical integration. It has voltage detection, frequency detection, and communication interfaces. Electrical, mechanical interlocking and other functions can realize automatic, electric remote and emergency manual control.
The operation is realized by the logic control board using various logical commands to manage the operation of the motor and gearbox. The motor drives the switch spring energy and instantly releases the acceleration mechanism to quickly connect and break the circuit or perform circuit conversion. The clearly visible state achieves safe isolation, which greatly improves various electrical and mechanical properties.
The overall design of the switch is a metal shell, which is small and sturdy. The switch and control part are metal shells. The switch shell parts are made of glass fiber unsaturated polyester resin, which has strong dielectric properties, protective capabilities and reliable operating safety.
The switch is suitable for automatic conversion between the main power supply and the backup power supply of the power supply system or automatic conversion and safety isolation of two load devices.
The switch has beautiful appearance, novelty, simplicity, small size and full functions, making it an ideal choice for different occasions.

Product use
Series automatic transfer switches are mainly used for AC
, Rated voltage
DC rated voltage
, rated current
to
In the power distribution or motor network, one main and one backup or mutual backup power switching system and mains power and generator set Load switching. At the same time, it can be used for infrequently connecting and breaking circuits and line isolation.
The products are widely used in power transmission and distribution system-level automation systems in fire protection, hospitals, banks, high-rise buildings and other important power supply places where power outages are not allowed.
Performance and features
Using double-row composite contacts, horizontal pull mechanism, micromotor pre-energy storage and microelectronic control technology, basically achieving zero arcing (no arc extinguishing cover)
It adopts reliable mechanical interlocking and electrical interlocking, and the actuator adopts independent load isolation switch, which is safe and reliable to use.
Adopting zero-crossing technology, it can be forcibly reset to zero in tight situations
(
cut off two power supplies at the same time
)
to meet the needs of fire linkage.
The load isolation switch switching is driven by a single motor, which ensures reliable and smooth switching, no noise and small impact force.
The operator drives the motor to pass current only when the execution load isolation switch switches. There is no need to provide operating current for steady-state operation. It saves significant energy. The execution load isolation switch is equipped with a mechanical interlocking device. Ensure that the common and backup power supplies work reliably and do not interfere with each other.
With obvious on-off position indication, padlock and other functions. Reliable distance between power supply and load.
It has good safety performance, high degree of automation, high reliability and a service life of more than
times.
Mechatronics design, switch conversion is accurate, flexible and smooth, using international advanced logic control technology, strong anti-interference ability, no external interference.
It has three stable operations: the main power is on, the backup power is on, the backup power is on, the main power is off, and the backup power is off.
It is easy to install, and the control circuit uses plug-in terminal links.
Four operating functions, emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control state, and automatic control operation.
Gitzo dual power supply GLD-100/4 automatic transfer switch has stable performance and high quality
