KDW127-18B Intrinsic Safety Explosion Proof Power Supply

Features: 1. Small size design makes installation and deployment more convenient; 2. AC127V~660V power supply is optional; 3. The built-in battery in the rated working state can continuously supply power for more than 2 hours, meeting the power supply requirements of the underground intrinsically safe equipment; 4. With overload, overvoltage, and overcurrent protection functions; 5. After the fault condition is restored, it will automatically resume work; 6. With a lock cover device to prevent the cover from being opened

Use environment: 1. Ambient temperature: 0℃～+40℃; 2. Average relative humidity: not more than 95% (+25℃); 3. Atmospheric pressure: 80kPa～106kPa; 4. There is a dangerous environment for methane and coal dust explosion in the coal mine, but no corrosive gas that destroys the insulation. 5. There is no strong vibration and impact. 6. Where there is no direct dripping or showering.
