(1/2) 001-01 / 20030905 / ea441_cxak0505.fm CXA Series CXA-K0505-VJL Power Supplies 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, 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. • The bottom of the board has a flat structure that facilitates insulation. • These parts are ultra-thin with a maximum thickness of only 6.3mm. TEMPERATURE AND HUMIDITY RANGES Operating 0 to +60 Storage –30 to +85 95max. Humidity range(%)RH [Maximum wet-bulb temperature 38°C] Temperature range (°C) • Safe design that includes a built-in overcurrent protection element. SHAPES AND DIMENSIONS 87max.
