The power supply unit has been designed with two integrated circuits LM317T. 
The trimmer potentiometer is used to control the output voltage (10 to 14V). In case of use of a battery, the output voltage is set to 13,6V to allow for re-charge of the battery. In case that the input voltage is cut, the battery is on. 
The power supply unit is suitable for powering of alarm systems and other devices that must be in continuous operation even in case of power mains failure. 
This device can operate also without a battery. 
- Input voltage - 22V. 
- Output voltage - 10 to 14V. 
- Output current - 3А. 
Overall dimensions PCB 84x34mm. 
The IC LM317T are installed on a aluminum heat sink. 

This product is an assembled module. 
Also available as an assembly kit - Product code 1051
