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 9A + 1A battery charging*

2. Output current 8A + 2A battery charging*

3. Output current 6A + 4A battery charging*

Total device current + battery charging current: 10A 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.
