Application
The »fpControl Measurement Unit – MM-3« (fpControl MM-3) is intended for use on AC generators with xControl or fpControl system. The module measures the AC voltage in three phases, the frequency and three times the AC current.
Product Description
- The current is measured directly from the module itself using three internal current sensors.
- The measuring range is 65 A per phase. Higher currents can be measured using optional external current sensors.
