COM pins is powered on. Dynamic Power Supply Control The NI-9266 uses a technique called dynamic power supply control featuring a DC- DC converter circuit, which allows reductions in power consumption from standard designs. The NI-9266 circuitry senses the output voltage and regulates the internal DC-DC converter in order to limit the power dissipation while maintaining the necessary compliance voltage for the given load and output current.
