Power Supplies 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.
