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).

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.
