====== Voltage Drop ======
When connecting a power supply to a DHD DSP core, concentrator or MADI concentrator the maximum allowed cable length depends on the power consumption of the connected device(s) and the cable diameter.
**Warning**\\ Maximum allowed voltage drop is 2.9V!
The following tables show the voltage drop on different cable length for different currents.
