The Profile of two Digits Count Down Displayer Briefly 1.Designed by the system of I.C. and anti-disturbance of software & hardware, which make it operate safely. 2.Using the high luminosity, low exhaustion, long M.T.B.F. LED, which make the Time Calculating steady function, well-distributed luminosity, high visibility and low power. 3.Easy to connect. Connects the eight inserting time randomly, the color can be combinated. Two Digits Count Down Displayer Spec. 1.Spec. 1-1.The size of each digit: 508mm(H) x 280mm(W) 1-2.The size of Appearance: 700mm(W) x 600mm(H) x 80mm(T) 1-3.Weight: 11.6Kg 2.Technology Parameter 2-1. Inputting Voltage: AC 85V~265V, 47Hz~63Hz 2-2. Power: Max Power��0W 3.Operation Environment 3-1.Operation Environment Temperature: -40��~ +74��3-2. Storage Temperature: -40��~ +100��4.Characteristic of Function 4-1. The regulator can meet the change of inputting signal &flash. The regulator can remember its cycle and outputting the time. 4-2. As soon as the public wire connect with the public wire of regulator. The count down displayer can record and display the color of lamp and all kind of flash; even the other wires connection randomly 4-3. Single inputting for Signal lamp is permitted. For example, if the user plans to use the red count down displayer, the user can connects the inputting wire to the red lamp only., then the count down displayer only displays red signal 4-4. Count Down system is Adjustable. When many signal inputting are connected and fit in with the formula Y=X1 + X2 +… The user can choose Y signal to display time or choose X1 signal to display time of X2…and the change is only according to the user if choosing the wire of Y signal is transmitted or not. .
