Input Voltage and Frequency Range

The operating range of line voltage shall be:

AC 90 volts to 264 volts, 47 Hz to 63 Hz

Power comsuption shall be under 190 Watts

Variation of the line voltage throughout the applicable operating range shall not result in any visible image

anomalies such as image movement, changes in light output, nor changes in image stability or quality.

Line Fuse

The AC input shall be fused and become electrically open as a result of an unsafe current condition. This

fuse is inside the power supply converter and is not user replaceable, and must be returned for

replacement.

This fuse shall be well selected to handle inrush current for all combinations of line voltage and frequency.

Hot plug and power on/off sequence

Once hot plug occurs, at the very first time, the initial current should be limited at 0.87 amps or lower when

power off. Current will stay below 100 m amps while power on, then ramp up to full power ( about 0.87

amps at AC 220 volts ) within 5 seconds when power-up signal is triggered. For the shut down sequence,

the current will stay at full power for about 150 m seconds or less, then ramp down to 100 m amps within

1 second.

Power on LED Location and Type

Power on indicator shall be easily visible from the front of the display.

Inverter
