The dual power control cabinet is mainly composed of a dual power automatic switching device, which can automatically switch between the common power supply and the standby power supply according to the need to ensure the reliability and continuity of the power supply.

It is widely used in high-rise buildings, posts and telecommunications, industrial and mining enterprises, shipping and other important places requiring uninterrupted power supply.

When the common power suddenly fails or outages, through the dual power switch, the standby power is automatically put into the backup power (backup power can also be powered by the generator under small load), so that the equipment can still run normally. The most common are elevators, fire protection, monitoring, lighting and so on.

Classification of dual power automatic switching switches: ATS and STS. STS is a static switch, also known as a static transfer switch, which is an automatic switching system for power supply.

The ATS is an automatic switch. The ATS is mainly used in the emergency power supply system to automatically change the load circuit from one power supply to another (backup) power supply.

Working conditions of dual power switch cabinet:

1, the ambient air temperature: the upper limit of the ambient air temperature +40℃, the lower limit of the ambient air temperature -5℃, the average value of the ambient air temperature for 24h does not exceed +35℃.

2, elevation: the elevation of the installation site does not exceed 2000m.

3, atmospheric conditions: the relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40℃;

It can have higher relative humidity at lower bottom temperature. The wettest month has an average maximum relative humidity of 90%,

At the same time, the monthly average minimum temperature of the month is +25 ° C, and takes into account the condensation that occurs on the surface of the product due to temperature changes.
