VPInstruments - 3 Phase Power Meter

• 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

• 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)

3 Phase Power Meter package

Complete your 3 Phase 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.

Monitor your compressor performance and efficiency

You can combine the power meter with one or more flow meters to monitor the compressor efficiency in real-time
