LZAQ2 dual power automatic transfer switch

LZAQ2 series automatic transfer switch (ATSE) is an automatic transfer switch that integrates switch and logic control, does not require an external controller, and truly realizes mechatronics. It is mainly suitable for distribution or motor networks with AC 50Hz, rated voltage 400V, and rated current 16 to 3200A. It is used for automatic conversion of the main power supply and backup power supply of the power supply system or automatic conversion and safety isolation of two load devices. It can also be used for isolation of circuits and lines that are not frequently connected and disconnected.
The control board manages the motor with logical commands. The motor drives the switch spring to store energy, and the acceleration mechanism is released instantly to quickly connect and disconnect the circuit and convert it. It achieves safe isolation through clearly visible status, greatly improving various electrical and mechanical properties.
The products are widely used in power transmission and distribution systems and automation systems in important power supply places such as fire protection, hospitals, banks, high-rise buildings, etc. where power outages are not allowed. The automatic transfer switch complies with the standards of GB/T14048.11 and GB/T14048.3. Electrical grade PC grade.

1. The upper limit of the ambient air temperature shall not exceed +40℃, the lower limit shall not be lower than -5℃, and the average value of 24h shall not exceed +35℃;

2. The relative humidity of the atmosphere shall not exceed 50% when the ambient air temperature is +40℃, and higher relative humidity can be achieved at lower temperatures. The average maximum relative humidity in the wet month is 90%, and the average minimum temperature of the month is +25℃, taking into account the condensation on the product surface due to temperature changes;

3. The installation location altitude shall not exceed 2000m;

4.Installation category is IV.

5. This product should be installed in a place without severe vibration and impact, and where the electrical components are not subject to unnecessary corrosion.

1.The double-row composite contact, horizontal pull-type closing and opening mechanism, micromotor pre-storage and microelectronic control technology are adopted to basically achieve zero arcing (no arc extinguishing cover). Reliable mechanical interlocking and electrical interlocking are adopted.

2.It has obvious on/off position indication, padlock and other functions, reliably realizes the isolation between power supply and load, has a service life of more than 8,000 times, and the electrical grade is PC grade

3.Mechatronic design, accurate, flexible and smooth switching

4.The switch has multiple input/output interfaces to facilitate remote PLC control and system automation

5.The switch does not require any external control components to work. It has beautiful appearance, small size and light weight.
