TBMHA1 Mains Harmonics Current Coupler
The TBMHA1 is a current coupler, primarily designed for mains harmonics measurements . It is built around a REO WKO/CL-P25 AC/DC compensated wideband current transformer, with the mains line passing through its core aperture.
The TBMHA1 produces a current proportional to the mains current of the connected load . Consequently, it requires a shunt resistor, which can be the input impedance of a DC -coupled measurement receiver or a BNC 50 Ohm feed-through termination attached to the current coupler output. The current transformer’s maximum primary current range is 25A, and its transducer factor is 1 mA/A. A 50 Ω termination results in a transducer factor of 50 mV/A.
The TBMHA1 is equipped with a 16A C19 connector at the mains input side and with country specific mains sockets at the mains output side.
