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
with current capacity:
1. Output current 5A + 0,5A battery charging
*
2. Output current 3,5A + 2A battery charging
*
Total device c battery: 5,5A 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.
