(1/2) 001-01 / 20030905 / ea442_cxam1112.fm CXA Series CXA-M1112-VJ Power Supplies DC to AC Inverters Connector type, Dimming, 7W, For 2 Bulbs TEMPERATURE AND HUMIDITY RANGES FEATURES * The CXA-M1112-VJ 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 CXA-M1112-VJ has an overvoltage protection device and a temperature fuse built-in, thereby achieving a safety design. * An alarm output function mounted on the CXA-M1112-VJ is useful to detect an occurrence of an error in lamps. Operating 0 to +60 Storage -30 to +85 95max. Humidity range(%)RH [Maximum wet-bulb temperature 38C] Temperature range (C) * Insulation is simplified due to flat backside surface of board.
