タイトルまたは説明

Product features: small size design, more convenient installation and deployment. AC**7V~**0V power supply is optional. The built-in battery in the rated working state can continuously supply power for more than 2 hours, meeting the power supply requirements of underground intrinsically safe equipment. With overload, overvoltage and overcurrent protection functions. After the fault condition is restored, it will automatically resume work. It has a lock cover device to prevent the cover from being opened when it is charged. The output end of the intrinsically safe power supply has a strong load capacity: load capacitance 4.7uF, inductance 0.*5mH.
