Electrical Characteristics

Power supply pins on the module's connectors limit the amount of input power. The following table provides an overview of the limitations for
pinout Type 6 (dual connector, 440 pins).

VCC_12V 12
VCC_5V-SBY 2
VCC_RTC 0.5

Rise Time

The input voltages shall rise from 10% of nominal to 90% of nominal at a minimum slope of 250V/s. The smooth turn-on requires that during
the 10% to 90% portion of the rise time, the slope of the turn-on waveform must be positive.

Power Consumption

The power consumption values were measured with the following setup:
• conga-TCA5 COM
• modified congatec carrier board
• conga-TCA5 cooling solution
• Microsoft Windows 10 (64 bit)
