1.1 General description
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of
48V DC
(+/-15%).
The PSU provides voltage of
U=54V DC
current efficiency:
1. Output current 4,5A + 0,5A battery charging
*
2. Output current 4A + 1A battery charging
*
3. Output current 3A + 2A battery charging
*
Total device c battery charging current: 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 protection, overvoltage and thermal overload protection. The
power supply is fitted with a fan for forced cooling, switching on depending on the temperature and the load of the
power supply.
