FEATURES

 The CXA-M1212-RJL 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.  Safe design that includes a built-in overcurrent protection ele- ment.  Insulation is simplified due to flat backside surface of board. TEMPERATURE AND HUMIDITY RANGES SHAPES AND DIMENSIONS TERMINAL NUMBERS AND FUNCTIONS No.CN1 ∗ Brightness can be controlled by adjusting VR within a range of 0 to 50k Ω.
