AEMC 3945-B 3945 B 2130.80 MN193 Three Phase Power Quality Analyzer

The AEMC 3945-B PowerPad Three-Phase Power Quality Analyzer is a hand held 3-phase power quality meter that has a large easy to read color graphical display.

 

Measurements are displayed graphically and numerically with colored waveforms. The menu driven meter features pop up functions which are push button activated. All necessary measurements are available for a comprehensive power system check or analysis to 830 Volts rms, 6500 Amps rms, along with a complete family of clamp on and flexible probes.

 

The 3945-B PowerPad has an event capture function, a transient capture function, a logging function, an optical RS-232, and advanced DataView software which can pilot the PowerPad as well as provide comprehensive reports.
