W2R Automatic Transfer Switch
The dual power automatic transfer switch is a newly developed miniature household power transfer switch. This switch is mainly used to test whether the main or backup power supply is working properly. When the normal power supply is abnormal, the backup power supply will immediately start working to ensure the continuity, reliability, and safety of power supply. Designed specifically for household rail installation and PZ30 distribution boxes, it complies with GB/T14048.11, Part 6-1 standards for low-voltage switchgear and control devices.
â—‰ Continuous Power Supply: Automatically switches to backup power when the normal power supply fails, ensuring continuous operation.
â—‰ Fast Switching Speed: Fast conversion and power-off time (<50ms) for seamless power transfer.
â—‰ Standard Compliance: Complies with GB/T14048.11 standards for ATSE switchgear and control equipment.
â—‰ Easy Household Installation: Designed for standard DIN rail installation and PZ30 power distribution boxes.
Features
Overview
The dual power automatic transfer switch is a newly developed miniature household power transfer switch. This switch is mainly used to test whether the main or backup power supply is working properly. When the normal power supply is abnormal, the backup power supply will immediately start working to ensure the continuity, reliability, and safety of power supply. This product is designed specifically for household rail installation and is specifically used for PZ30 distribution boxes.
According to GB/t14048.11, Part 6-1: Multifunctional Equipment and Switchgear specifies that ATSE is the most compliant low-voltage switchgear and control device.
Product Model and Classification
Normal Operating Time and Installation Conditions
Surrounding air temperature: The highest temperature shall not exceed 40 ô€€€, the lowest shall not be lower than -5 ô€€€, and the average temperature within 24 hours shall not exceed 35 ô€€€
Altitude: The sea level at the installation site should not exceed 2000m
Atmospheric conditions: When the highest temperature reaches 40 ℃, the relative humidity of the installation site should not exceed 50%; When the temperature reaches the lowest temperature of -5 ℃ and the relative humidity is high, for example, when the temperature is 25 ℃, the relative humidity is 90%. Due to temperature changes, special measures should be taken to address occasional condensation on the surface of the product.
Pollution level: TSE pollution level meets the specified level 3 of GB/t14048.11
Installation category: The installation type of TSE complies with the specified category in GB/t14048.11
Installation conditions: TSE can be vertically installed in control cabinets or distribution cabinets. Ensure that the installation distance meets the requirements in Figure 1.
Installation and Wiring
Please check the integrity of TSE before installation. Then use the joystick to turn on and off TSE, check the flexibility of the transmission device, and detect the generation and disconnection conditions of the load at each stage of the normal and backup power supply
Control voltage detection: AC50HZAC220V. The coil in the control circuit should not be too long. The cross-sectional area of copper wire should not exceed2.0mm²
According to the installation requirements of the power distribution system, please equip appropriate circuit breakers to ensure the safety of personnel and equipment.
