Hobut's M850-LRC is a unique combination of a 3 phase digital universal metering system and Rogowski coils. It can be used on any voltage system with a wide range of inputs, and incorporates a universal AC or DC auxiliary power supply. One unit covers the majority of applications and wiring systems without any modification required, making the M850-LRC ideal for stocking.
The M850-LRC supports up to three Rogowski coils for measuring current. By combining the meter with one or more M240-RCM coils the M850 can measure current up to 4000A. To maintain accuracy and resolution, three ranges of the meter can be ordered: 0‐500 0‐2000A or 0‐4000A. Example: Nominal current is 400 Amps, you would choose the 0‐500A meter.
