CXA Series CXA-P1212A-WJL
DC to AC Inverters
Connector type, Dimming, 8W, For 2 Bulbs
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 con-
trol(VR:0 to 10kΩ).
• 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 insula-
tion for high voltage components.
APPLICATIONS
Various types of color liquid crystal displays, computer touch pan-
els, controllers, medical devices, ATMs, POS terminals, telecom-
munication terminals, microscope monitors, fishdetectors, ticket
sales machines, amusement arcade machines.

According to a connection method, either a voltage control brightness
adjustment or a resistance control brightness adjustment can be selected
as follows:
Voltage control brightness adjustment: 0V → Maximum brightness
adjustment (Maximum light volume), 0.6V → Minimum brightness
adjustment (Minimum light volume)
Resistance control brightness adjustment: 0Ω → Maximum brightness
adjustment (Maximum light volume), 10kΩ → Minimum brightness
adjustment (Minimum light volume)
