Power Specifications
Tables 1 through 3 define the current draw values of the three RuffSystem models, featuring either the
LittleBoard 735, COM 840, or the LittleBoard 800. The tables capture In-Rush, Idle, and Burn-In-Test
currents at incremental input voltages from +14 to +32 VDC.
Table 1 lists the current draw values of the RuffSystem with the LittleBoard 735.
Operating configurations:
• In-rush operating configuration includes one LittleBoard 735, 2GB DDR2 RAM, AMI BIOS, I/O
board, AC/DC external digital power supply, DC/DC internal power module, CRT monitor, HDD,
keyboard and mouse.
