Functions and
characteristics
Power-monitoring unit
Circuit Monitor Series 2000
E60626
The CM2150, CM2250, CM2350 and CM2450 Circuit Monitors have the following
functions:
customary measurements: instantaneous and min/max values of voltage, current,
power, energy, power factor, frequency, etc.
measurement of harmonic distortion of current and voltage per phase
accumulated energy metering
alarm/event waveform capture and recording (voltage sags/swells)
Operation with a PC is possible via a Belden type communication cable or an
Ethernet gateway.
Applications
Panel instrumentation
Sub-billing / cost allocation
