(PC Class) Isolated Ddual Power Automatic Transfer Switch
LTZQ2 series PC-class isolated dual-power automatic transfer switch is an automatic transfer switch that integrates switch and logic control, does not need an external controller, and truly realizes mechatronics. It has voltage detection, frequency detection, communication interface, and electrical and mechanical interaction. Lock and other functions can realize automatic, electric remote, and emergency manual control.
The operation is realized by the logic control board using various logic commands to manage the operation and operation of the motor and gearbox. The motor drives the switch spring to store energy, and the acceleration mechanism is released instantaneously to quickly connect and break the circuit or perform circuit conversion. Through the obvious visible state Realize safe isolation, and greatly improve the electrical performance and mechanical performance.
The overall design of the LTZQ2 switch is marble-shaped, compact, and sturdy. It has strong dielectric properties, protection ability, and reliable operation safety.
The switch is suitable for the automatic conversion between the main power supply and the backup power supply of the power supply system or the automatic conversion and safety isolation of two load devices. The switch has a beautiful appearance, novelty, simplicity, small size, and full functions, making it an ideal choice for different occasions.
Standards compliant
●LTZQ2 series automatic transfer switch conforms to series standards:
●IEC 60947-1(1998) /GB/T 4048.1 “General Rules for Low-Voltage Switchgear and Control Equipment”
●IEC 60947-3(1999)/GB 14048.3″Low-voltage switchgear and control equipment, low-voltage switches, isolators, disconnectors, and fuse combinations”
●IEC 60947-6(1999)/GB 14048.11″Low-voltage switchgear and control equipment multifunctional electrical appliances No.1Article: Automatic Transfer Switching Appliances”
Performance and Features
●Adopt double-row composite contacts, horizontal pull mechanism, micro-motor pre-storage energy, and micro-electronic control technology, basically realize zero flashovers (no arc extinguishing cover);
●Reliable mechanical interlock and electrical interlock are adopted, and the actuator adopts an independent load isolation switch, which is safe and reliable to use;
●Using zero-crossing technology, it can be forced to zero in an emergency (cut off two power supplies at the same time), meeting the needs of fire linkage;
●The switching load isolation switch is driven by a single motor, the switching is reliable and stable, with no noise and small impact force; The drive motor of the manipulator only passes current at the moment when the load isolation switch is switched, and there is no need to provide a working current for steady-state work, which saves significant energy;
●Executive load isolating switch is equipped with a mechanical interlocking device to ensure reliable operation of common and standby power sources without interfering with each other;
●With obvious on-off position indication, padlock, and other functions, it can reliably realize the isolation between power supply and load;
●Good safety performance, high degree of automation, high reliability, the service life of more than 8000 times;
●Mechanical and electrical integration design, accurate, flexible, and smooth switching, adopts international advanced logic control technology, strong anti-interference ability, no external interference;
●There are three kinds of stable work (1-O-Ⅱ) with the main power on and the backup power off; the main power off and the backup power on; both the main and backup power off;
●Easy to install, the control circuit is connected by plug-in terminals;
●Four operating functions: emergency manual operation, electric remote control operation, emergency disconnection operation in an automatic control state, and automatic control operation.
