1. Technical description.
1.1. General description.
The buffer power supply is designed in accordance with the requirements of the EN 50131-6 standard,
grade 1÷2 and II environmental class. It is intended for an uninterrupted supply of alarm system devices requiring
stabilized voltage of
12V DC (+/-15%).
A linear stabilizing system, which has been used in the unit, provides
voltage with a lower level of noise and a quicker response to interference when compared to a switched-mode
regulator.
