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
with current capacity:
1. Output current 18A + 2A battery charging
*
2. Output current 16A + 4A battery charging
*
3. Output current 12A + 8A battery charging
*
Total device c battery: 20A 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.
