Tekbox TBMHA1 Mains Harmonics Current Coupler

Tekbox TBMHA1 Mains Harmonics Current Coupler

The Tekbox TBMHA1 is a current coupler, primarily designed for mains harmonics measurements. It is based on a REO WKO/CL-P25 AC/DC compensated wideband current transformer, with the mains line passing through its core aperture.

The Tekbox 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 Ω feed-through termination attached to the current coupler output. The current transformer’s maximum primary current range is 25 A, 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 16-A-C-19 connector at the mains input side and with country specific mains sockets at the mains output side.

• Mains voltage range 100...120 V/200...240 V; mains voltage selection switch.
• Max. mains current 16 A, depending on country specific mains output socket.
• Transducer factor 50 mV/A with 50 Ω load resistor (DC coupled).
• Mains input socket C19, 16 A.
• Mains output socket country specific; CEE7/3 16 A (Schuko), NEMA 5-15 15 A, AS/NZS 3112:201 15 A, BS1363, 13 A.
• Current output socket BNC female.
• Dimensions (mm, WxHxL) 100 x 118 x 240; 1.4 kg.
