FEATURES

 The CXA-M1112-VJ is an inverter for cold cathode fluorescent lamps and features a built-in dimmer.  Because they employ advanced output current control, fluctua- tions in input voltage, load, and distributed capacitance have vir- tually no effect on brightness.  Output open and short circuit conditions result in no damage, heat generation, or other difficulties.  The CXA-M1112-VJ has an overvoltage protection device and a temperature fuse built-in, thereby achieving a safety design.  An alarm output function mounted on the CXA-M1112-VJ is use- ful to detect an occurrence of an error in lamps.  Insulation is simplified due to flat backside surface of board.

ELECTRICAL CHARACTERISTICS

∗1 Vbr also operates as a remote function as follows: 0 to 3.5V: Operated 4.5V or higher: Operation stopped ∗2 An alarm output is a detection terminal for detecting an OFF state of the lamps, with a delay time from an occurrence of the OFF state (See the diagram). For details of the alarm output, see the individual specifications.
