Single-Phase Measurements

Three-phase AC motors have been the workhorse of industry since the earliest days of electrical engineering. They are reliable, cost-effective and need little or no maintenance. Today’s PWM drives enhance the flexibility of these motors to provde a fully functional, reversible variable speed drive.

Voltech’s Power Analyzers will make very accurate measurements of power and harmonics on all kinds of electrical machinery. For PWM drives, our power analyzers will make simultaneous measurements on all stages of a drive.

PM3000
Three Phase Power Analyzer

Unique PWM motor drive mode locks onto wide range of fundamental frequencies from 0.1Hz to 1kHz. Total W, V, A, etc. measurements are made to the full 1MHz bandwidth. No data is lost.
The accepted industry solution to single phase and multi phase power measurements

PM6000
New Generation Power Analyzer

Up to 6 channel configurable, for example 3 wattmeter, three-phase input, DC bus and two-wattmeter drive output and torque and speed measured simultaneously.
High rejection of common-mode signals found on the drive output.
Samples continuously without gaps at 5MSPS so there is no missing data during integration or low power standby measurements
