Shunt-based precision current measurement module that accumulate current over time. Shuntmon is our second evolution replacing the Sendyne sensor.

ShuntMon works with any of our WatchMon range.


  • Current ± 500 A peak (400 A continuous)
  • Maximum Voltage = 650v DC


  • Turnkey solution for use in the field 
  • Typically achieves ±1.0 % accuracy of current measurement 
  • Resolves currents from 3 mA to 500A 
  • Low power consumption 
  • Built-in calibration for current and voltage measurements
  • built in isolation for power and serial communication
