(2) Ripple of supply voltage
Examples of the power supply connection
(3) Inverter current wave
Please note that the ripple at the input connector of the module should be within the values shown in this table.
If the ripple is beyond these values, the noise may appear on the screen.
In the luminance control mode, the rush current below flows into the inverter of the module. The duty cycle
varies from 100% through 20% depending on the luminance control level. This might cause the noise on the
screen. Please evaluate the appropriate value of the capacitor in the filter to eliminate the noise.
Acceptable range
Note The acceptable range of ripple voltage includes spike noise.
