DC to AC Inverters
Connector type, Dimming, 2W, For 1 Bulb
FEATURES
• The CXA-K0505-VJL is an inverter for cold cathode fluorescent
lamps and features a built-in dimmer.
• Because they employ advanced output current control, fluctua-
tions in input voltage, load, and distributed capacitance have vir-
tually no effect on brightness.
• Output open and short circuit conditions result in no damage,
heat generation, or other difficulties.
• The bottom of the board has a flat structure that facilitates insu-
lation.
• These parts are ultra-thin with a maximum thickness of only
6.3mm.
• Safe design that includes a built-in overcurrent protection ele-
ment.
