Features: indoor / outdoor applicable; reach maximum size (6.0x3.0) M2, far ahead of peers; control system and brushless motors with built-in, no external master, moisture and dust, and longer life. Installation, operation and maintenance is very easy multi-screen display, effectively enhance advertising effectiveness (2-10 fold display advertising content in limited advertising space); screen adjustable dwell time (3 to tens of seconds), can be a real limit 24 hour unattended self-running; more than one box can be wired or wireless communication, to achieve synchronous operation, consisting of stirring linkage screen advertising; 24VDC brushless motor, rolling power system operation, in addition to general AC power supply, but also may be made of solar energy, wind, and other battery-powered general; systems with wired or wireless synchronized scrolling interface, enabling multiple synchronized scrolling light boxes; smooth and reliable operation (using pulse control the positioning of the electronic reel, no external drive mechanism, simple structure, low noise); National Peer only non-contact magnetic sensors locate the origin of the principle of creative use of system reliability works best screen positioning using self-learning mode, precise positioning, but also has the function automatically eliminate scroll position error; the system has over-current automatic overload protection, when the system is in overload, the system will automatically restart three times, as the system still does not automatically restart, this time to check the cause of the overload requires human; system uses slow start slow rolling stop mode ("S" type start-stop mode, on the one hand to ensure that the screen smooth operation, on the other hand protect the system components to reduce the mechanical impact, mechanical systems and longer life two-year warranty and lifetime maintenance; scrolling system parameter table 63 Series 100 Series Model SAT-SH-63 SAT-SH-100 63mm 100mm diameter drum roll Shaft material aluminum profiles scroll size (width / area) 3.5m / 3.5X1.5㎡ 6m / 6X1.5㎡ Motor type brushless DC motor system voltage 24VDC power supply 100VAC ~ 240VAC or 24VDC Maximum power 40W 100W fastest within 0.35m / s 0.55m / s synchronization with wired and wireless function
