Smart Linkage Power Supply Box 220V DC Input High-Capacity Low-Voltage

1. Product Overview

The model-type power supply box is a DC24V large-capacity power output device. In the fire alarm control system, it can be used as the power source for the linkage control system to supply power to the linkage control modules and controlled devices. This power supply complies with the national standards GB4717-2005 and GB16806-2006. It belongs to a low-voltage DC regulated power supply and is suitable for various building automation systems such as fire alarms, fire protection linkage control devices, fire protection broadcast communication devices, fire extinguishing control devices, and combustible gas detection devices.

This power supply uses an alternating current of 220V as the main power source, and at the same time, it has two built-in sealed lead batteries with a specification of DC12V/7Ah as the backup power source. It adopts a switching power supply voltage regulation circuit and a backup power floating charge circuit. It has functions such as automatic protection against overcurrent output, main and backup power switching, and a complete backup power automatic charging function as well as backup power over-discharge protection function.

Meanwhile, it can monitor the status of the main power, backup power, and power output. It can report faults of the main power, backup power, and output faults. It also has the function of displaying the output voltage and output current, allowing for an intuitive observation of the working status of the power supply box.
