inverter used. Normally, power supply with 3.5Amp current output should enough for most of 4x CCFT panels. Although
the controller provides power regulation for the LCD power this does not relate to the power supplied to the backlight
inverter. If an unregulated power supply is provided to an inverter any fluctuations in power may affect operation,
performance and lifetime of the inverter and or backlight tubes.
23. External panel power input
: Allow to supply external power to the panel separately for max 3.3V (7A) or 5V (7A) or 10V
(5A) or 12V (5A) or 18V (3.5A) via PP4 power input connector. Corresponding jumper setting of JA3, JA5 & JA6 are
required for each panel power input by referring to page 14.

Power output
: Note the controller has an overall 3Amp current limit and the current available from the auxiliary power
output will be dependent on the power input and other system requirements.
•
••
•
Power Safety
: Note that although only 12V / 24VDC is required as ‘power-in’ a backlight inverter for panel backlighting
produces significantly higher voltages (the inverter does not connect to the ground plane). We strongly advise
appropriate insulation for all circuitry.
•
••
•
EMI
: Shielding will be required for passing certain regulatory emissions tests. Also the choice of external Controller to PC
signal cable can affect the result.
•
••
•
Ground
: The various PCB mounting holes are connected to the ground plane.
•
••
•
Servicing
: The board is not user serviceable or repairable. Warranty does not cover user error in connecting up to the
controller and is invalidated by unauthorized modification or repairs.
•
••
•
Controller Mounting
: It is recommended that a clearance of at least 10mm is provided above and 5mm below the
controller when mounted. Additionally consideration should be given to:
•
Electrical insulation.
•
Grounding.
•
EMI shielding.
•
Cable management. Note: It is important to keep panel signal cables apart from the inverter & backlight cables to
prevent signal interference.
•
Heat & Ventilation: Heat generated from other sources, for example the backlight of a very high brightness panel
may generate significant heat which could adversely affect the controller.
•
Other issues that may affect safety or performance.
•
••
•
PC Graphics Output
: A few guidelines:
•
Signal quality is very important, if there is noise or instability in the PC graphics output this may result in visible noise
on the display.
•
Refer to graphics modes table in specifications section for supported modes.
•
Non-interlaced & interlaced video input is acceptable.
IMPORTANT: Please read the Application Notes section for more information.
