Backup power supply designed in accordance with the requirements of EN 50131, grade 1 ÷ 2. It is intended for an uninterrupted supply of alarm system devices that require a stabilized voltage of 12 VDC (+/- 15%). The linear stabilization system, which has been used in the unit, provides voltage with a lower noise level and a faster response to interference compared to a switched mode regulator. Power supply: 230VAC / 50Hz. Power supply output: (1) 2A / 13.8VDC - for general application (2) 0.58A / 13.8VDC - for grade 1, 2. Battery charging current: 0.2A / 0.5A. Supported battery: 7Ah / 12V. Current consumption by PSU systems: 15 mA max. Protections: SCP, OLP, OVP, UVP, sabotage (opening of the enclosure). Technical outputs type OC: EPS - 230V AC power failure, APS - battery failure. Compliance with standards: EN50131, level 1 ÷ 2, EN60839-11. Dimensions: 205 x 237 x 82 [+/- 2mm] (ground clearance: 8mm). Surface mounted box, locked - bolted.
