Product Details

Product Overview

Nowadays, with the rapid development of science and technology, power system equipment is gradually developing in the direction of centralized monitoring and intelligence, that is, weak current (electronic) control of strong electricity. According to the actual needs of foreign technology and domestic users, the company has developed a new generation of intelligent dual-power automatic switching system. It takes the microcomputer control system as the core, adopts electromagnetic compatibility design, strong anti-interference, long-term stable and reliable work, and is equipped with a large screen backlight LCD display to form a good man-machine dialogue interface for users, and the operation warning is simple and highly intelligent, which is an ideal mechatronics dual power supply automatic switching system. It has created a new era of dual-power automatic switching system in the direction of intelligence and networking, and is an ideal replacement product for similar products in China.

Model Meaning

Scope of Application

TN1QC intelligent dual-power automatic switching system is suitable for AC 50Hz, rated voltage 400V, rated current to 1250A dual-channel power supply power supply system, to achieve automatic switching between common power supply (N) and standby power supply (R) (can also be set to manual switching), so that dual-power supply users can realize unattended substation. This product is suitable for special and Class I power systems, high-rise buildings, residential quarters, military facilities, hospitals, airports, docks, shopping malls, communications, fire protection, metallurgy, chemical industry, textiles, petroleum, coal mines and other important places that do not allow power outages.

Conditions of Normal Use

◇ The ambient air temperature is -5°C ~+40°C, and the average value of 24 hours does not exceed +35°C;

◇ Atmospheric conditions: clean air, relative humidity at the maximum temperature of +40 °C does not exceed 50%, at lower temperatures allow higher relative temperature, such as 90% at +20 °C, but it should be taken into account that due to humidity changes, condensation may occur;

◇ The altitude of the installation site shall not exceed 2000 meters, and it shall be used indoors;

◇ This product should be installed in a place where there is no violent vibration and impact, and it is not enough to make the electrical components suffer from corrosion;

◇ If the above conditions cannot be met, it should be resolved through negotiation between the user and the manufacturer;

◇ When this product is used in offshore oil and nuclear power plants, a separate technical agreement shall be signed.

Ordering Instructions

When ordering, the user should indicate the model of the intelligent system, the specification of the circuit breaker frame current, the number of poles, the rated trip current, the function, and the switching mode according to the model and meaning in the text.
