Feature:1. APPLICABLE CURRENT: The conversion switch is a PC level infrequent conversion switch, with dual station design(A is the common power supply, B is the standby power supply), suitable for AC 5060hz AC system2. PREVENT POWER FAILURE: The main function of the automatic transfer switch is that when the main power supply(common power supply A) fails, the automatic transfer switch will automatically switch to the standby power supply(standby power supply B) to continue working(switching speed is less than 50 milliseconds), which can effectively solve the failure caused by power failure3. TEMPERATURE RANGE: The operating temperature of the power transfer switch range from 5 to +40, and the average temperature within 24 hours should be lower than +35. The storage temperature ranges from 25 to +55, and can reach +70 in a short time(within 24 hours)4. INSTALLATION NOTE: When the ambient temperature is +40, the relative humidity of the installation site shall not exceed 50%. The lower the temperature, the higher the relative humidity. For example, when the average minimum temperature in the wettest month is +20, the monthly average maximum relative humidity for that month can reach 90%. Appropriate measures should be taken to prevent condensation due to temperature changes5. POLLUTION DESCRIPTION: The dual power transfer switch has a pollution level of 3 (conductive pollution, or dry non conductive pollution become conductive pollution due to condensation). The ATS can be installed vertically or horizontally in the cabinetSpecification:Item Type: Dual Power Automatic Transfer SwitchRated Current In: 63AInsulation Voltage Ui: 690VACGrade: PCFrequency: 50/60HzStandard: IEC60947-6Rated Short Circuit Current Limit(RT16-00/63A): 50KA.Package List:1 x Dual Power Automatic Transfer SwitchNote:Maintenance and inspection should be carried out by professionals.1. To ensure the good performance of the ATS, the first maintenance and inspection should be conducted within 6 months of use. Subsequently, maintenance and inspection should be performed at least once a year. In harsh installation conditions, the frequency of maintenance and inspection should be increased.2. Check for deformation and damage to electrical contact parts, and clean the surface. 3. Metal particles and local burning. Rust, oxidation, and dust on the contact surface can result in poor contact, so manual operation and measurement of the necessary contact resistance should be performed.4. If the ATS is damp or has not been used for a long time, dry before connecting the power. After removing dust, use a 500V megohmmeter to measure the insulation resistance of the normal power source and the AC power source. The insulation resistance, including the load side and both poles, should not be less than 10MQ when using live parts and metal plates.
