Model:EC-7VAR

Description

The EC-7VAR Energy Logger is designed to Monitor and record energy usage on a 3-phase supply (or 3off Single-phase). The EC-7VAR also records the Power Factor to aid with the calculation of Real (W), Reactive Power (VAR) and apparent (VA) Power.

It is also widely used for:

  • Monitoring Voltage and Current Fluctuations for fault diagnosis and reporting to the power provider
  • Investigating the required size of Backup Generators and UPS systems, plus subsequent monitoring
  • Voltage Optimisation -  This can help reduce Energy Costs significantly ! Many pieces of electrical equipment are capable of working at lower mains voltages, so by using Voltage optimisation systems to reduce the mains to lower levels where possible, savings can be made in energy usage. The first step in this process is to monitor the incoming voltage levels, for which the EC-7VAR is ideal.
  • Power Factor (known as PF or Cos φ) is recorded for the voltage channel L1 and the current channel A1, this is then used to calculate the real (Watts), reactive (VARs) and apparent (VA) power for all 3 phases within our Electorosoft software. PF measurement also allows users to determine if Power Factor Correction is needed for the site.

Easy Set-up using the included Windows based software. The stored data can be uploaded to the supplied Electrosoft software for further storage and analysis.

Two input ranges are available on the unit (4-400A or 20A to 3kA) with 2 casing designs (standard IP43 or IP65).

NOTE: Optional IP65 Casing is available under the "Recommendations Products" area below.
