brightness range. This brightness range is
achievable with virtually any LCD display.
dimming input that permits brightness
control from either, a DC voltage source,
a PWM signal or external potentiometer.
externally programmable (through the
input connector) at either 10mA or 12mA
(5mA or 6mA per lamp). This allows the
inverter to match the panel’s lamp current
specifications, or it can be used to
purposely drive the lamps at a lower or
higher current to decrease or increase
nominal brightness. The inverter also has
a dedicated FAULT pin that indicates an
open/shorted lamp condition.
