Advanced power quality functions, unprecedented energy analysis capability

Think of the Fluke 435 series II Power Quality and Energy Analyser as your insurance policy. No matter what goes wrong in your facility, with the 435 you will always be prepared. Equipped with advanced power quality functions and energy monetization capabilities, there is no electrical issue this model can’t handle.

Applications

  • PowerWave data capture – capture fast RMS values to determine voltage, current and frequency interaction
  • Measuring power inverter efficiency
  • Energy monetisation – calculate the fiscal cost of energy waste due to poor power quality
  • Energy assessment – quantify the before and after installation improvements on energy consumption
  • Front line troubleshooting – quickly diagnose problems on-screen to get your operation back on line
  • Predictive maintenance – detect and prevent power quality issues before they cause downtime
  • Long-term analysis – uncover hard-to-find or intermittent issues
  • Load studies – verify electrical system capacity before adding/changing loadings

Summary

The new 430 Series II Power Quality and Energy Analysers offer the best in power quality analysis
and introduce, for the first time ever, the ability to quantify the cost of energy losses.
The new Fluke 435 Series II helps locate, predict, prevent, and troubleshoot power quality problems
in three and single-phase power distribution systems. Additionally, the Fluke-patented energy loss
algorithm, Unified Power Measurement, measures and quantifies energy losses due to harmonics
and unbalance issues, allowing the user to pinpoint the origin of energy waste within a system.

Feature Overview

Simultaneously measure AC O/P power and DC I/P power in power electronics, to determine Power inverter efficiency.
Capture fast RMS data, show half-cycle and waveforms to characterize system dynamics (generator start-ups, UPS etc.).
Classic active and reactive power measurements, unbalance and harmonic power, to pinpoint the fiscal costs of energy loss.
Troubleshoot real-time and analyse the trends using cursors and zoom tools.
600V CAT IV/1000V CAT III rated for use at the service entrance, providing the highest safety rating in the industry:
Measure all three phases and neutral with enhanced thin flexible current probes to fit into the tightest places.
Automatic Trending: Every measurement is always automatically recorded, without any set-up.
Monitor ten power quality parameters on one screen as defined in EN50160 power quality standard.
Configure data logger for any test condition with memory for up to 600 parameters at user set intervals.
View graphs and generate reports using the analysis software included.
Seven hours operating time per charge on the Li-ion battery pack.
Standard compliance to IEC 61000-4-30 Class A
C1740 Soft Case
8GB SD card (32GB max)

(Includes the following accessories TL430 test lead set,4xi430 thin flexi current probes, BP290 battery, BC430 power adapter with international power adapter set, USB cable A-B and CD)
