1. Technical description.
1.1 General description
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of 24V DC
(+/-15%). The PSU provides voltage of U=27,6V DC current efficiency:
1. Output current 3A + 0,5A battery charging
*
2. Output current 2,5A + 1A battery charging
*
Total device c battery: 3,5A 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.
