KDY660/24B Flame-proof and Intrinsically Safe DC Power Supply for Coal Mines
Product description
KDY660/24B flame-proof and intrinsically safe DC power supply for coal mines (hereinafter referred to as the power supply) is class ia power supply, which mainly supplies power to underground ia-class sensors and equipment. The power supply has multiple outputs and is completely isolated. Each power supply has overvoltage, overcurrent and short circuit protection, etc. The backup battery uses an environment-friendly battery pack.
Features
◎The power output has the functions of current-limiting, voltage-limiting, and short circuit protection, as well as automatic recovery after the fault is removed;
◎The backup power supply has the functions of overcharge, over-discharge, over-temperature, and short circuit protection. It can work continuously for more than 4 hours under full load in case of AC power failure.
◎The power supply can remotely charge and discharge and maintain the backup power supply. Maintenance personnel can remotely force battery discharge and AC power recovery through the upper computer of the ground station.
◎The power supply has the functions of uploading information such as AC and DC status, battery and voltage of backup power supply. The information can be uploaded to the substation and displayed through isolated RS485.
◎The main power supply has local LCD display function, which can monitor the output voltage, battery information and parameter setting.
