Description
Power Supply Unit Overview
The main function of this power supply is to convert AC220V voltage to DC26.5V, and it has the functions of standby power supply charge function. The standby battery provides the output of DC24V/24Ah when AC220V stops supplying, which plays a continuous role in the work and start-up of the linkage equipment.
The display function of this power supply is comprehensive, with output voltage display, output current display, main power fault, standby power fault, line fault and other fault indication, and overload, over-current, short circuit protection function.
TD7808 Intelligent Power Supply Unit has RS485 networking function, which can be connected with the TX7002/TX7008 series fire alarm control panel, and provide the corresponding linkage, fault and status information for the fire alarm control panel.
