Dimming/Connector Type
CXA-0308
■ Features
■ Applications
●2-output
●Applicable panel size*: 10 to 12 inches
●With brightness control function (Pulse Wide Modulation mode).
●With shut down function.
●With a sensing function for running out of lamp (alarm output).
●In the high-voltage generator(a terminal and a pattern),
an anti-dust measure by silicone application is taken.
(Notice) Applicable panel size becomes a standard.
