Solution of backup power supply system of highway traffic safety lights

Product Overview

Operating principle of iron phosphate backup battery system: Two circuits are under charge and one circuit is under discharge, the batteries at low voltage can be charged by 220V input power and then output the voltage that matches the highest operating value of the battery system via the charging adapter, to charge the battery system; the battery system can also be powered by solar panels. When the lights cannot be used normally due to the power failure of the power grid or the instability of the circuits, the battery system can immediately supply the power to them to ensure their stable operation in any emergency. After the emergency is released and the lights are turned off, the battery system enters the charging process. The battery system has a self-protection function, when the battery is charged fully or its voltage is too low, it can be disconnected from the external circuit by itself to ensure that its performance is not affected.

 

Operating Principle

The road traffic safety guidance lights are new technology products developed for the safety protection of road traffic under fogging and other poor weather conditions. The products focus on the early warning and collision prevention of fogging area on expressways and ordinary highways. The backup power supply of the guidance lights is mainly used to solve the problem that the lights cannot be operated normally due to power failure in any emergency and can quickly respond to the power supply demand to ensure the traffic safety of the vehicles.
