I would like a Phidget that could work as a DC power distribution unit.
Features:
  • 12 outputs
  • 20A max per output
  • 75A max per box
  • works at DC 12-60V
  • PWM support
  • current measurement of each output
  • Set a max current of each output before it disconnects (also handles momentary in-rush current) (basically the reset-able fuse size)
  • Current/Voltage Sampling rate <1sec
The controller can set:
  • the PWM duty cycle
  • on/off
  • reset over current fault
  • max current set independently for each output
The data the controller would receive:
  • current measurement for each channel
  • if it is in fault mode
  • the voltage for the whole device.
Bonus:
  • it also works for AC120V@15A
  • the DC voltage can be independently controlled at each output provided the base voltage is higher.
