## Description

It ensures automatic switching between the DC source and the 12V battery for uninterrupted power supply of equipment, powers the consumer from the main source and charges the battery when there is voltage, instantly switches to the battery when the mains fails, the charging start and stop thresholds are adjustable from potentiometers, supports up to 10A and has compact dimensions.
The Automatic Power Supply Switching Module (UPS) represents an advanced and intelligent solution for managing power supply in power outage or emergency situations. This complex device integrates several essential functions, including automatic switching between power sources (battery and mains charger), automatic battery charging during normal power supply and providing an emergency circuit in case of power failure.
The module allows automatic switching between the power supply from the main source and the reserve battery in case of power interruption, ensuring an uninterrupted power supply for critical equipment.
During normal power supply, the module automatically detects the state of the battery and starts the charging process, ensuring a battery ready for use in case of emergency.
The control board allows configuration of switching parameters, battery charging and discharging thresholds and other settings to suit specific application requirements.
In case of power failure, the module automatically activates the emergency circuit, allowing the continuation of power for critical devices until normal power is restored or until the battery is discharged.
While there is power from the mains charger, the module supplies the consumer and charges the battery. Consumption from the battery is realized only in the absence of the main power supply.
The two potentiometers set the charging start voltage for the battery and the battery charging stop voltage.
