Automatic Dual Power Supply Transfer Switch - CB Changeover Micro-cutoff ATS NLQ4-125-4P 400V

Features:1.SAFE PROTECTIVE COVER: This product has a reasonable structure, small size, attractive appearance, and a protective cover, making the power supply safer and more reliable.
2.ENSURES NORMAL CHARGING: When the power supply fails (only test for normal phase A voltage and maintain phase A voltage; only test for voltage drop or phase loss), it will automatically connect one or more of the power supply's charging circuits to another power supply to ensure normal power supply charging.The power supply circuit provides good protection function.3. SILENT AND ENERGY SAVING: EPS firefighting power interface, reliable DC12~24V, long-distance dual-point connection, quiet operation, energy saving, easy installation, simple operation, reliable and stable performance
4.COMPLETE PROTECTION FUNCTIONS: Comes with short-circuit protection, overload protection, undervoltage protection, as well as fire protection, dual output and stop signal functions
5. Wide application: Widely used in the installation and operation of lighting circuits in office buildings, shopping malls, banks, train stations, hospitals, and high-rise buildings with fire protection requirements.

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 2000 meters. 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 changes in temperature.4.Low pollution levels, no severe vibrations or shocks, no corrosive environment, no severe dust, no conductive particles or explosive hazardous substances, no strong electromagnetic interference
