Fluke 437 Series II 400Hz Power Quality and Energy Analyzer

Fluke 437 Series II 400Hz Power Quality and Energy Analyzer

The Fluke 437 Series II is a three-phase power quality and energy analyzer built for systems running at 400Hz as well as standard mains frequencies. It detects and quantifies the power quality problems that disrupt sensitive equipment, and it logs energy use over time so you can find waste and prove the result of any corrective work. The 400Hz capability makes it the tool of choice for aviation, maritime and military power systems.

Brand and standards

Fluke is one of the most trusted names in electrical test and measurement, and Powerpoint Engineering is an authorised Fluke distributor in Ireland. The 437 Series II measures the disturbances that compromise equipment operation and efficiency, including voltage sags, swells, transients, harmonics and flicker, so faults can be characterised before they cause downtime. As with all our power quality instruments, the analyzer can be calibrated in our own laboratory to keep its readings traceable and dependable.

Applications

The 437 Series II suits demanding power quality and energy work across specialist and general electrical environments:

• Power quality diagnostics on 400Hz aviation, maritime and military supplies
• Locating voltage sags, swells, transients, harmonics and flicker that disrupt equipment
• Energy assessments to track consumption and identify wasteful usage
• Verifying the effectiveness of energy-saving measures over a logging period
• Inverter efficiency measurement on renewable energy and backup power installations

FAQs

Will the Fluke 437 Series II work on 400Hz aircraft and marine systems?

Yes. The 437 Series II is designed for 400Hz operation as well as standard mains frequencies, which is why it is widely used on aviation, maritime and military power systems. It captures the same power quality parameters on those supplies as it does on conventional installations.

Can it measure inverter efficiency on renewable and backup systems?

Yes. The analyzer includes inverter efficiency measurement, so you can assess how well a system converts direct current to alternating current. That makes it useful for diagnosing and maintaining solar, other renewable, and backup power installations alongside its core power quality work.

Can Powerpoint Engineering calibrate my Fluke 437 Series II?

Yes. Our in-house calibration and repair laboratory services Fluke power quality analyzers and issues traceable certificates. Speak to our calibration team to book your instrument in and keep its measurements reliable.
