Product Description
General
YCQ9HB ATS appliances are suitable for AC 50Hz, rated working voltage 400V and below, rated current 10A to 63A dual power supply system, the power supply system of the twopower sources: common power supply (N) and standby power supply (R) at the same time detection, when the power supply occurs undervoltage, phase failure power supply failure that is, automatic switching from the abnormal power supply to the normal power supply (can also be manually switched), to enhance the continuity and reliability of the power supply system in the use of the premises.
This improves the continuity, safety and reliability of the power supply system at the place of use.Switching appliances are widely used in power systems, hospitals, postal and telecommuni- cation, firefighting, hotels, banks, airports, wharves, residential neighborhoods, TV stations, facilities, shopping malls and other important places where the continuity of power supply is required.
Standards: IEC 60947-6-1.
Operating conditions
1. The ambient air temperature is -5 °C ~ +40 °C, and the average temperature within 24h does not exceed 35 °C.
2. The altitude of the installation site does not exceed 2000m above sea level.
3. The relative humidity of the air at the installation site should not exceed 50% at an ambient temperature of +40°C. Higher relative humidity is possible at lower temperatures. For example, in the wettest month with an average minimum temperature of +20°C, the monthly average maximum relative humidity for that month can be up to 90%. Appropriate measures should be taken to prevent condensation due to tem- perature changes
4. The pollution level is 3. There is no danger of explosion in the surrounding air, and there are no gases or conductive dust that could corrode metals and destroy insulation.
5. The installation category is III.
6. The two power lines are connected to the upper end of the switching appliance and the load line is connected to the lower end, and must not be reversed.
7. The installation site should be free from significant vibration and shock.
