The unit accepts 110-240V AC mains input and regulates it to the 24VDC supply required by Aperta monitor and door station components.\u003c\/p\u003e\n\u003cp\u003eDesigned for installation in consumer units or distribution boards as part of a residential or commercial door entry system, the unit mounts on standard 35mm DIN rail and occupies approximately 90mm of rail width. The bus separator function isolates the monitor circuit from the door station circuit to prevent interference and voltage drop over longer cable runs, which can cause audio distortion or video signal degradation in systems with extended distances between components.\u003c\/p\u003e\n\u003cp\u003eThe housing measures 90mm wide by 60mm high by 105mm deep and weighs 270g unboxed. A power LED on the front panel confirms mains input and correct operation. Only one power supply is required per single-way system regardless of the number of monitors or door stations fitted, as long as the total current draw remains within the 800mA output rating.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.27\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e9.6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e95\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e115\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e410\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e310\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e260\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_APPOWSWDR_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_APPOWSWDR.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many power supplies does a single-way system need?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOne power supply unit is sufficient for a complete single-way system regardless of how many monitors or door stations are connected, provided the combined current draw does not exceed 800mA.
