Feature: 1. Automatic Transfer: When the normal power supply is abnormal, the switch will automatically switch to the standby power supply, making it work immediately. 2. Continuous Power Supply: This switch can be switched in milliseconds without interruption, which ensures the continuity, reliability and safety of the power supply. 3. Sturdy Construction: This automatic transfer switch has the characteristics of firm structure, conversion, convenient installation and maintenance, and long service life. 4. Premium Material: The silver contact improves the conductivity and service life of the switch, and the flame retardant PC shell has good insulation, high temperature resistance and anti aging. 5. Wide Application: This switch can be widely used in various places where continuous power failure is not allowed, such as factories, shopping malls, nurseries, etc. Specification: Item Type: Automatic Transfer Switch Material: PC and silver Model: CHLT 125 2P Insulation Voltage: AC690V Rated Voltage: AC400V Coil Voltage: 230VAC Level: PC level Specifications: 2P Life: Electrical: 2000 times Mechanical: 5000 times Rated Short Circuit Current: 50kA : RT16-00-63A Rated withstand Voltage: 8kV Control Circuit: Rated Control Voltage Us: AC220V 85% Us-110% Us Auxiliary Circuit: Two relays, each with two sets Contact Capacity: AC220V50HZ le=5y Touch Time: <50ms Operation Transition Time: <50ms Return Time: <50ms Off Time: <50ms Package List: 1 x Automatic Transfer Switch 1 x Instruction Note: 1. The maximum ambient temperature should not exceed 40℃, the minimum should not be lower than ‑5℃, and the average temperature within 24 hours should not be higher than 35℃ 2. The altitude of the installation site should not be higher than 2000m 3. When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%; when the temperature is the lowest temperature of ‑5℃, the relative humidity is higher, for example, if the temperature is 25℃, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on product s due to temperature changes How to use: Check the integrity of the ATS before installation, turn the ATS on or off with the operating handle, check the flexibility of the transmission and detect the normal and backup power load generation and disconnection conditions at each stage
