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 10A + 1A battery charging*
2. Output current 7A + 4A battery charging*
Total device current + battery: 11A 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.
