3 Phase Power Meter

The VPInstruments 3 Phase Power Meter is the highly accurate power meter for your permanent power measurements. With the power meter, you can measure the voltage and current of all three phases. It provides power, voltage, current, cos(phi), and many more electrical parameters via the RS485 (Modbus RTU) interface.

Please select if you would like to add current transformers

Description

3 Phase power meter Features/ Benefits

True RMS power measurement of single-phase or three-phase systems
One size fits all: one model for 100 to 600 Vac, 50 / 60Hz
RS485 (Modbus RTU) output
Wye or delta in one model
For permanent installation
0.3333 VAC input for current transformers (CT)
LED indicator for CT status and serial communication
Configurable using Modbus

Applications

Power consumption of large consumers (i.e. compressors, dryers, pumps, water chillers)
Submetering
Cost allocation
Baseline condition monitoring
Energy management
Efficiency calculations (i.e. compressor electrical usage vs output)

Power meter package

Complete your power meter with current transformers. For each phase measured, you will need a current transformer. Check the maximum amperage and select the right transformer for your 3 Phase Power Meter.
