The 3-channel PW3337 can measure DC and a variety of power connections ranging from single-phase 2-wire to 3-phase 4-wire. Ideal for development and production of motors, inverters, power conditioners, power supplies, and other devices, it allows assess and verify the energy-saving performance of industrial equipment such as heavy machinery, air- conditioners as well as household appliances.

Main features

  • Voltage, current, and power basic accuracy: ±0.1%
  • Measurement frequency bands: DC, 0.1 Hz to 100 kHz
  • High-current measurement: up to 65 A, direct input
  • Low-loss current input: input resistance of 1mΩ or less
  • Harmonic measurement up to the 50th order: IEC 61000-4-7 compliant
  • High-accuracy measurement, even with a low power factor: ideal for no-load testing of transformers and motors
  • Measure up to 5000A AC: built-in external sensor input terminals
