In stand-alone mode, logic outputs from the primary amplifier are used to trigger the switching of each individual channel to the backup amplifier. In network control mode, switching is determined by the IED GLOBALCOM\u003csup\u003e®\u003c\/sup\u003e system supervision sub-system. In network control mode, multiple 1544BAS units can be used to switch multiple primary amplifiers to a single backup amplifier unit. When used in this manner, all switching logic is accomplished through network commands and the logic inputs are not used.\u003c\/p\u003e\u003cp\u003eThe 1544BAS is powered using standard PoE and draws a maximum power of 3 watts. If PoE equipment is not used or the unit is used in stand-alone mode, an input is provided for an external +48VDC power supply. A green power indicator LED is included to show that the unit is powered on. Each channel has a yellow LED indicator that illuminates when the channel is switched to the backup amplifier input.\u003c\/p\u003e\u003cp\u003eWhen not in network control mode, each channel can be switched to the backup using a contact closure on the corresponding logic input.\u003c\/p\u003e\u003cp\u003eThe 1544BAS is provided in an enclosure that either mounts to a DIN rail or is screwed down on a panel or wall to allow for convenient installation close to the amplifiers in the equipment rack.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e  \u003ctable\u003e \u003ctbody\u003e\n\u003ctr\u003e \u003ctd\u003eInput Voltage Range\u003c\/td\u003e \u003ctd\u003e48VDC (PoE Compliant with IEEE 802.3af)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eOperating Temperature Range\u003c\/td\u003e \u003ctd\u003e–22˚F – +149˚F (–30˚C – +65˚C)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePower\u003c\/td\u003e \u003ctd\u003e4-Watts Max\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMax Current\u003c\/td\u003e \u003ctd\u003e8 Amps\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eHeight\u003c\/td\u003e \u003ctd\u003e7.01\" (17.81cm)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWidth\u003c\/td\u003e \u003ctd\u003e3.50\" (8.90 cm)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDepth\u003c\/td\u003e \u003ctd\u003e2.00\" (5.08 cm)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWeight\u003c\/td\u003e \u003ctd\u003e9.6 oz (272 g)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWarranty Period\u003c\/td\u003e \u003ctd\u003e 36 months from date of purchase \u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Atlas Sound","offers":[{"title":"Default Title","offer_id":43886902804523,"sku":"AS-IED1544BAS","price":1068.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/3019\/5243\/files\/IED1544BAS-1__47532.1731434935.1280.1280.png?v=1775673126","url":"https:\/\/www.empirepro.com\/products\/atlas-sound-ied1544bas","provider":"Empire Pro","version":"1.0","type":"link"}
