Unipower Unilyzer 900 Power Network Analyser

SKU: Unilyzer 900 S-T

A challenge for power distribution companies is to maintain a stable voltage supply in the customer delivery point. Customer complaints are often based on unstable voltage conditions. This can be due to varying loads in the customer installation. The combination of load and network impedance must therefore be monitored to determine best solution.

The Unilyzer 900 is designed for electric power distribution companies to explore customer complaints but it can be used by anyone wanting to troubleshoot problems or to do optimisations in the power network.

The integrated wireless modem and router allows automatic, remote download of data as well as realtime analysis and configuration. You can easily connect to Unilyzer 900 from any computer or smartphone.

  • Measures power and energy in all 3-phase Wye and Delta configurations
  • Unique method for data compression and storage saving memory usage and thus saving transfer times and costs

  • 170 days of measurements with 32 MB standard memory

Integrated Wi-Fi

The instrument has integrated Wi-Fi. You easily connect to Unilyzer 900 from any computer or smartphone. Use your Android smartphone or tablet to check the voltage in an easy, safe and hassle-free way.

Real-time Possibilities

Independent of measurement mode, realtime values are shown on the display and can be read from an external PC or via modem simultaneously. Evaluation of voltage sags with norm classification according to different standards and planning levels.

Evaluation and Analysis

The powerful evaluation software PQ Secure is included. The Unilyzer 900 can be integrated into a full size PQ Secure PQ Management System allowing full automatic PQ administration and analysis.


All accessories are designed for practical field use from years of experience. Small, flexible Rogowski type clamps for currents up to 5000A available as well as magnetic core clamps. Transducers have automatic range and type identification (no user action needed). There is a variety of practical instrument bags available that are approved as cabin baggage on airplanes. Highly appreciated magnetic holder available for electrical cabinets.
