(1/2) DC to AC Inverters Connector type, Dimming, 8W, for 2 Bulbs Conformity to RoHS Directive CXA Series CXA-P1212A-WJL FEATURES * Optimum one-connector, two-output design for thin liquid crystal panel displays. * This inverter carries a PMW(pulse modulation width) circuit, TDK's unique circuit design. This allows dimming of lighting over a much wider range than is possible using conventional types of dimmer circuits. The type of dimmer control can be selected as desired, either voltage control(Vbr:0 to 1.6V) or resistance control(VR:0 to 10k). * Built-in overcurrent protection circuit increases safety. * Monitor brightness is always kept stable since the built-in current feedback illumination stabilization circuit compensates for inverter input voltage variation(10%). * The board backside is free of wiring pattern. Cost reduction and simplified mounting are made possible by a design that only uses one side of the board. * Operational safety is increased by the use of two types of insulation for high voltage components. * It is a product conforming to RoHS directive. APPLICATIONS Various types of color liquid crystal displays, computer touch panels, controllers, medical devices, ATMs, POS terminals, telecommunication terminals, microscope monitors, fishdetectors, ticket sales machines, amusement arcade machines.
