1.FEATURES:
• The CXA-0231 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
A PWM (pulse-width modulation) circuit mounted on the CXA- 0231 enables a brightness adjustment range to be wider than that of the conventional type.
• 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.
• The high-voltage terminal is coated with silicone so as to reduce a possibility of an occurrence of a defect caused by dust.
