รายละเอียด:
Specially designed for transport applications
The Fluke 437 Series II 400Hz Power Quality and Energy Analyzer is designed specifically for the defense and avionics industries. Capable of measuring up to 400 Hz, the 437 II is a must-have for those working in submarines, aircrafts, and other transport applications.
Applications
400 Hz measurement – capture power quality measurements for avionic and military power systems.
PowerWave data capture – capture fast RMS values to see every waveform so you can determine how the voltage, current and frequency values are interacting.
Power inverter efficiency – measure both ac power and dc power, in and out, to monitor the efficiency of inverters.
Energy monetization – calculate the fiscal cost of energy waste due to poor power quality.
Energy assessment– quantify the before and after installation improvements in energy consumption to justify energy saving devices.
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.
Long-term analysis – uncover hard-to-find or intermittent issues.
Load studies – verify electrical system capacity before adding loads.
