1.3.1.5 Input signal Quality

(1) Rise/Fall time
Video Signal : less than 2.0ns
Horizontal SYNC : less than 50ns
Vertical SYNC : less than 100ns
(2) TTL Signal Level
The levels of Horizontal & Vertical SYNC will be TTL level, their high
level will be 2.4-5.5V, and low level will be 0-0.2V.
(3) Video Signal Level
The video signal when terminated with an idea 75ohm termination will have a range of 0V to
0.7V(nominal), and its full scale output will be 0.7V and black level will be between 0V and
0.1V.

1.3.2 Power Supply Requirements

1.3.2.1 Input Power Requirements

(1) Input Voltage Range
The unit shall meet all the operating requirements with an input voltage range of 90-264 VAC
(universal)
(2) Input Current
Maximum
Input Current
(MAX) 3.5 Arms 90Vac -- 264Vac
(3) Frequency Range
The unit shall operate within a frequency range of 47Hz to 63Hz.
(4) Inrush Current
Power supply inrush current shall be less than 60A for all conditions of line voltage (cold-start).
(5) Regulator Efficiency
70% minimum (measuring at 115Vac and full load)
(6) Power line Transient Immunity
The power supply shall function properly after being subjected to a 0.3us/1.2us, 2000 volt high
peak pulse, or 5ns/10ns, 1500 volt fast peak pulse applied either differentially or single
endedly to line and neutral at any phase of the power line voltage and shall not cause an
unsafe or unrecoverable errors to the horizontal frequency of the display unit.
(7) Maximum power consumption: 135 Watts (preset size); 150W (with USB function)

1.3.2.2 Output Power Requirements

The power circuit shall supply DC power outputs as followings:
