Fluke 435 Power Quality Analyzer meter helps you locate, predict, prevent and troubleshoot problems in power distribution systems. These easy-to-use power quality tools are a “must have” for any person who maintains or troubleshoots three phase power. The new IEC Class A standards for flicker and power quality are built right in to take the guess work out of power monitoring.

Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance
Automatic Transient Mode: Capture 200 kHz waveform data on all phases simultaneously up to 6 kV
Fully Class-A compliant: Conduct tests according to the stringent international IEC 61000-4-30 Class-A standard
Measure all three phases and neutral: With included four current probes
AutoTrend: Every measurement you see is always automatically recorded, without any setup
System-Monitor: Up to ten power quality parameters on one screen according to EN50160 power quality standard
Inrush mode: For troubleshooting nuisance circuit breaker tripping
View graphs and generate reports: With included analysis software
Logger function: Configure for any test condition with memory for over 400 parameters at user defined intervals
Mains signaling: Measure interference from ripple control signals at specific frequencies
Battery Life: Seven hours operating time per charge on NiMH battery pack

Applications

Frontline troubleshooting – quickly diagnose problems on-screen to get your operation back online
Predictive maintenance – detect and prevent power quality issues before they cause downtime
Quality of service compliance – validate incoming power quality at the service entrance
Long-term analysis – uncover hard-to-find or intermittent issues
Load studies – verify electrical system capacity before adding loads
Energy assessments – quantify energy consumption before and after improvements to justify energy saving devices

Features:

Complete three-phase troubleshooting tool: measures virtually every power system parameter: voltage, current, frequency, power, power consumption (energy), unbalance and flicker, harmonics and inter-harmonics. Captures events like dips and swells, transients, interruptions and rapid voltage changes.
The Fluke 435 features 0.1 percent voltage accuracy making it fully compliant with the IEC 61000-4-30 Class A standard
Logger function: record the detail you need. Detailed, user-configurable long-time recording gives you the MIN, MAX and AVG readings of up to 100 parameters on all 4 phases with selectable averaging time down to 0.5 seconds. Enough memory is available to record 400 parameters with 1 minute resolution for up to a month.
Four channels: simultaneously measures voltage and current on all three phases and neutral.
Auto Scaling: easier trend analysis with automatic scaling of the vertical axis you will always use the full display to view the waveforms.
Automatic transient display: captures up to 40 dips, swells, interruptions or transients automatically.
Meets the stringent 600 V CAT IV, 1000 V CAT III safety standard required for measurements at the service entrance.
Rugged, handheld instrument operates for more than 7 hours on included rechargeable NiMH battery pack. Menu-driven interface simplifies operation.
Extensive data analysis possibilities. Cursors and zoom can be used ‘live’ while taking the measurements, or ‘offline’ on stored measurement data. The stored measurements can also be transferred to a PC with FlukeView software.
The Fluke 435 comes with Power log software to analyze recorded data and to create reports.
Complies with IEC 61000-4-30 measurement standards
