Feature: 1. SAFE PROTECTIVE COVER: This product has reasonable structure, small size, beautiful appearance, and has a protective cover, which makes the power supply safer and more2. ENSURE NORMAL LOAD: When the power supply fails (only test the normal A phase voltage and maintain the A phase voltage, only test the loss of voltage or phase loss), will automatically connect one or more load circuits from the power supply to another power supply to ensure normal power supply load. The power supply of the circuit ensures a good protection function 3. NOISELESS AND ENERGY SAVING: EPS power interface, DC12~24V , long distance double point, bring noiseless , energy saving, easy installation, simple , and stable performance 4. COMPLETE PROTECTION FUNCTIONS: Come with short circuit protection, overload protection, under voltage protection, as well as fire protection, output and shutdown functions 5. WIDE APPLICATION: Widely used in the installation and use of lighting circuits in office buildings, shopping malls, banks, stations, hospitals and high rise buildings with fire protection requirements Specification: Item Type: Power Automatic Transfer Switch Package List: 1 x Power Automatic Transfer Switch1 x User Manual 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 2000meter. 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 surfaces due to temperature changes. 4. Low pollution level, no serious vibration and shock, no corrosive environment, no serious dust, no conductive particles and explosive dangerous substances, no strong electromagnetic interference |
