Power Supplies
CXA Series CXA-L0612A-VJL
DC to AC Inverters
For 1 Bulb, 5W Diming
This DC to AC inverter unit is designed for dimming-type cold cathode lamps. This inverter can be used for lighting a wide range of
single cold cathode fluorescent lamps.

FEATURES
• Use of output current control avoids effects resulting from input
voltage, load, and distributed capacitance variation.
• This inverter unit is appropriate for use with 6 to 13 inch LCDs
since the typical open circuit voltage(initial lamp ignition voltage)
is 1.8kVrms.
• Safe design that includes a built-in overcurrent protection
element.
• Insulation is simplified due to flat backside surface of board.
• Excellent inverter for ignition of U-shaped cold cathode
fluorescent lamps.
