CXA Series CXA-P1212-VJL
DC to AC Inverters
For 2 Bulb, 7W Diming
FEATURES
• The CXA-P1212-VJL is an inverter for 2-cold cathode
fluorescent lamps and features a built-in dimmer.
• Because they employ advanced output current control,
fluctuations in input voltage, load, and distributed capacitance
have virtually no effect on brightness.
• Output open and short circuit conditions result in no damage,
heat generation, or other difficulties.
• Built-in fuse assures a high degree of safety.
• The bottom of the board has a flat structure that facilitates
insulation.
• Ideal for 10- to 14-inch class LCD panels.
