TBMHA1

Mains Harmonics Current Coupler

The Tekbox TBMHA1 is a mains harmonics current coupler designed for mains current and harmonics measurements in conducted emission and power quality setups. It uses a compensated wideband current transformer to produce an output proportional to the mains current, enabling accurate measurement of fundamental and harmonic components with a DC-coupled measurement receiver or spectrum analyzer.

Features

Key capabilities and advantages

  • Designed for mains current and harmonics measurement in conducted noise and EMC testing.
  • Built around a wideband current transformer that provides proportional current output to the mains current.
  • Requires a shunt resistor or 50 Ω termination for compatible measurement systems.
  • Provides a standard BNC-female output for connection to spectrum analyzers or measurement receivers.
  • Includes country-specific mains sockets for convenient connection and testing setups.
  • Suitable accessory for mains harmonics analysis using Tekbox receivers such as the TBMR-110M.
