Power Supply Electrical Specifications
The power supply for this product is an internal converter, with a non-replaceable fuse internally. This
converter shall be well designed to meet CE mark requirement.
Input Voltage and Frequency Range
The operating range of line voltage shall be: AC 100 volts to 240 volts, 50 Hz to 60 Hz. Power comsuption
shall be under 291 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 2.3 amps or lower when
power off. Current will stay below 100 m amps while power on, then ramp up to full power ( about 2.3 amps
at AC 120 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
