The mobile explosion-proof safety box (referred to as the mobile power supply) is a product developed and designed for temporary electric field use. It uses liquid crystal display to display voltage, current, and leakage current data, and a microcomputer to monitor and display the safe use of electricity in the process of power supply. It facilitates on-site personnel to make judgments on electricity safety. It is a new type of explosion-proof power supply suitable for IIB and IIA explosive gas environments and frequent mobile electric field equipment.
