1.1 General description 
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of 12 V DC 

 (+/-15%). The PSU provides voltage of U=13,8 V DC current efficiency: 

 

                                               1. Output current 6A + 1A battery charging 
                                               2. Output current 5A + 2A battery charging 

                                       Total device c battery: 7A max. 

 
 

         In the case of power failure from prime supply, the unit is instantly switched to battery 
assisted operation.

 

The power supply unit features: short circuit, overload, surge and over voltage 

protections.
