Feature: 1. Power Transfer Switch: The dual power automatic transfer switch is a miniature household power switch, which is mainly used to test whether the main power supply or standby power supply is normal, so as to ensure the continuity, reliability and safety of the power supply. 2. Quick in Switching: When the normal power supply is abnormal, the standby power supply will work immediately to ensure the continuity, reliability and safety of power supply, and millisecond level switching can achieve the effect of continuous power supply. 3. PC and Silver Contact: Premium flame retardant PC material is used, with good insulation, high temperature resistance, aging resistance, safety and reliability. The use of silver contact can greatly improve the conductivity and service life of the switch. 4. Wide Application: Switch to the standby power supply in case of power failure, and switch to the main power supply when power restores. It is widely used in various places where continuous power failure is not allowed, such as factories, shopping malls, nursery farms, etc. 5. Compact Design: The ATS has compact structure, reliable transmission, convenient installation and maintenance, and long service life. Specially designed for household rail mounted installation, specially used for PZ30 distribution box.

Package List: 1 x Dual Power Automatic Transfer Switch1 x User Manual Note: 1. The maximum ambient temperature shall not exceed 40℃, the minimum temperature shall not be lower than ‑5℃, and the average temperature within 24 hours shall not be higher than 35℃. 2. The altitude of the installation site shall 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 ‑5℃, the relative humidity is high, for example, the temperature is 25℃, and the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with the occasional condensation on the product surface.
