Feature 1Good Materials: Premium flame retardant PC plastic material has good insulation, high temperature resistance, anti aging, safe and reliable, while the silver contacts can greatly improve the conductivity and service life. 22 Operation Modes: Can be operate automatically or manually, millisecond switching without power failure, compact structure, reliable transmission, convenient installation and maintenance, and long service life. 3Easy Installation: Dual power automatic switch is a miniature household power switch that is mainly used to test whether the main power supply or standby power supply is normal. This product is specially designed for track installation and is dedicated to PZ30 power distribution box. 4Quick Switching: When the normal power supply is abnormal, the standby power supply works immediately, and millisecond level switching ensures continuous power supply as well as the continuity, reliability, and safety of power supply. 5Wide Application: Switch to standby power supply when power failure occurs, and switch to main power supply when power restoration occurs. It is suitable for emergency power supply systems with a 50 or 60 Hz AC rating of 230 V. Widely used in various situations where continuous power outages are not allowed.SpecificationItem Type: Dual Power Automatic Transfer SwitchMaterial: PC, silver.

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 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 ‑5, the relative humidity is higher, for example, when the temperature is 25, the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with occasional condensation on the surface of the product.
