1. Technical description.
1.1. General description
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of
12V DC
(+/-15%).
The PSU provides voltage of U=
13,8V DC
current efficiency
I=5A+0,5A battery charging
*.
In the case
of power failure from prime supply, the unit is instantly switched to battery assisted operation.
During normal operation, the total current drawn by the equipment may not exceed I = 4,5A.
Maximum battery charge current: 0,5A. Total device c battery: 5A max
