! Power Supply Voltage: +5 V

± 5%, +12 V ± 5%

! Power Consumption:

– Max:

2.26 A @ 5 V, 0.5 A @ 12 V

– Typical:

1.22 A @ 5 V (w/Celeron M 1 G + 256 MB RAM)

0.01 A @ 12 V (w/Celeron M 1 G + 256 MB RAM)

! Operating temperature: 0 ~ 60° C (32 ~ 140° F) operation

! Operating humidity: 0% ~ 90% Relative Humidity, non-condensing

Note! If your power supply doesn’t have +12 V output (+5 V only), PCA-6781

needs to go T-part number to add the components for the 5 V to 12 V

converting circuit, but LVDS and PC104 also cannot be used within +5 V

only.
