TH3421/TH3422 Series Four-Channel Digital Power Meter

TH3421/TH3422 Series Four-Channel Digital Power Meter

The TH3421/TH3422 Series is a four-channel digital power meter designed for multi-channel electrical power measurement and harmonic analysis. It is suitable for laboratories that need to measure several voltage and current paths simultaneously, such as input/output power, multi-output devices, three-phase systems or complex power-electronics workflows.

The manufacturer lists the TH3421/TH3422 Series with 0.15 percent basic accuracy, voltage range from 5 V to 600 V, current range from 10 uA to 20 A, power range from 5 mW to 12 kW and frequency range from 45 Hz to 420 Hz. The series is identified as a four-channel digital power meter with harmonic analysis capability.
