Supply Voltage Standard Power

• 12V DC ± 5%
The dynamic range shall not exceed the static range.
1.4.1

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 2 (dual connector, 440 pins).
Power Rail Module Pin Current
Capability (Amps)
VCC_12V 16.5
VCC_5V-SBY 2
VCC_RTC 0.5
1.4.2

Rise Time

The input voltages shall rise from 10% of nominal to 90% of nominal at a minimum rise time 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.
