The Swiss Way of Measuring Power: Infratek and the Future of Electric Motor Testing

When precision matters, Infratek delivers.

At Duncan Instruments, we’ve worked with a lot of power analyzers—but none quite like the Infratek 108B Series. Designed and manufactured in Switzerland, these instruments are trusted around the world for their accuracy, simplicity, and flexibility.

If your work involves electric motors, inverters, drives, or renewable systems, the Infratek 108B deserves a spot on your bench.


Built for Engineers. Trusted by Industry.

The Infratek 108B measures more than 280 parameters per phase with ±0.02% accuracy and bandwidth up to 2 MHz. Whether you’re analyzing a three-phase induction motor, a BLDC system, or a power inverter, this analyzer gives you what you need—with no fluff.

Single, three, and four phase models
Real-time display and fast data logging
Transient and Power-Speed modes for startup analysis
Harmonic FFT up to the 88th order
Scalable analog and frequency inputs
Optional high-accuracy current sensors up to 700 A


A Better Way to Test Motors

In applications from R&D labs to production lines, the 108B is changing how engineers work.

With just one instrument, you can measure:

  • Input and output power

  • Torque, slip, and speed

  • Power factor and harmonics

  • Efficiency vs. load

  • Motor inductances and resistances

It even supports no-load and blocked rotor tests, logging directly to Excel or through Infratek’s Windows software.
