Description

Plug and play power meter for all your measurements

Easy and simple: just open the power meter and wrap around the power cable you want to measure. The rate at which it blinks is proportional to the output current. The VPLog-i offers the best solution for power measurements in audits or in less critical measurements.

The VPLog-i is available in two models, where the main difference is the output signal.

  • VPLog-i offers a 4..20mA and pulse output.
  • VPLog-i-R features an RS485 (Modbus RTU) output.

Power meter features/ benefits

  • Very easy and quick installation
  • Plug and play
  • For short-term and permanent measurements

Applications of the VPLog-i

  • 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)
