(1/2) 001-01 / 20030919 / ea436_cxal0605.fm CXA Series CXA-L0605-VJL Power Supplies DC to AC Inverters Connector type, Dimming, 4W, For 1 Bulb FEATURES • The CXA-L0605-VJL is an inverter for 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. • Safe design that includes a built-in overcurrent protection element. • Insulation is simplified due to flat backside surface of board.
