PMM-10 Power Measuring Module

 

D&V’s PMM-10 Power Measuring Module is a precision measuring system that is suitable for use when testing hybrid electric motors, motor controllers/drives, BSG/ISG’s and other rotating electrical devices.

 

The modular PMM-10 can be assembled with a maximum of 10 modules per rack, and a second rack can be added, to tailor it for the specific measurement requirements of the application.

 

PMM-10 Module

• Fast data - 10 Mhz Burst data, 200 kHz Streaming data

• Numerous power and efficiency calculations

• Synchronized calculation of Power and Efficiency values

• Fast Data for Improved Resolution and Anomaly Detection

 

Available modules:

• Voltage / Current Input Module

• Analog Input Module

• Position Sensing Module

• USB Interface Module

 

Features

• Standard 19” rack mount format; 13U including patch panel

• Displays RMS and MRV values of Voltage and Current signals

• Selectable buffer periods: 1T, 10T or 100T

• Burst data at 10 MHz for 50 ms with configurable trigger and pre-trigger buffer size

• All data measurement channels are synchronized to within 100 nanoseconds

• Calculated values (Power, Efficiency, etc) are also synchro- nized to within 100 nanoseconds of measured data

• Various formulas for calculated values can be implemented on raw or sinusoidally filtered data:

- Active Power

- DC Power
