The maximum power consumption of the SCB-68 is a function of the signal conditioning components installed and any circuits constructed on the general-purpose breadboard area. If the SCB-68 is powered from the host computer, the maximum +5 V current draw, which is limited by the fuse, is 800 mA. Fuse Manufacturer ..........................................
