An intermediate power supply designed for uninterrupted supply to devices that require a stabilized voltage of 12 VDC (+/- 15%). The power supply provides a voltage of U = 13.8 VDC with an output current of I = 2 Amp + 0.5 Amp for battery charging. In the event of a power failure, a backup battery is immediately activated. The unit is built on the basis of switched power supply, with high energy efficiency. The power supply is housed in a metal housing (RAL9003 color) that can accommodate a 7Ah / 12V battery. A microswitch indicates the opening of the door (front cover). Power supply: 176 ÷ 264VAC / 50Hz. Power supply output: 2A / 13.8VDC. Battery charging current: 0.5Amp. Mounting battery: Supports 7Ah / 12V. Efficiency: 87%. Protections: SCP, OVP, OLP, UVP, anti-sabotage (opening of the enclosure). Dimensions: 170 x 180 x 82 [+/- 2 mm]. Notes: Surface mounted box, locked - bolted (locking assembly possible).
