1. Technical description.
1.1. General description.
The AC/AC PSAC 08246 power supply is designed to supply HD cameras or other devices requiring stabilized
voltage of 24V AC or 27V AC and total capacity of 6A@24V AC. It features 8 outputs protected independently with glass
or polymer fuses. Output voltage range is step-adjustable by appropriate jumpers, independently for each AUX output.
The PSU is housed in a metallic enclosure that features a microswitch indicating unwanted opening of the front door
(faceplate).
