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.
