Pulsar AWZ110 13.8V 1A 7Ah buffer, linear power supply unit Grade 2

Pulsar AWZ110 13.8V/1A/7Ah linear, buffer power supply unit with technical outputs

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.
Depending on a required protection level of the alarm system in the installation place, the PSU efficiency and the battery charging current should be set as follows:

• Grade 1, 2 - standby time 12h: output current 0,58A + battery charging current 0,4A

General use – if the PSU is not mounted in an installation complaint with the EN-50131 standard, the acceptable current efficiency amounts to:

• Output current 1A (without a battery)
• Output current 0,6A + 0,4A battery charging current

Total current of the receivers + battery charging current is max. 1A.
In case of power decay, a battery back-up is activated immediately. The PSU is housed in a metal enclosure with battery space for a 7Ah/12V battery. It is fitted with micro switches indicating unwanted door opening (front panel).
