TU40RGI / TU40RGV / RC / TEH-132 current sensors for LV monitoring: low-power CTs, Rogowski coils, Hall sensors
Country: Spain · Model: TU40RGI / TU40RGV / RC / TEH-132
This is a group of current sensors for extended monitoring of low-voltage networks, where an ordinary transformer with a 5 A secondary is inconvenient. It includes TU40RGI and TU40RGV with a Ø40 mm window, the flexible RC Rogowski coil, and the TEH-132 Hall sensor for DC and AC current.

Description
TU40RGI is intended primarily for neutral current or the protective earth conductor, and is potted in resin, so it is also suitable for outdoor installation. It comes with a built-in two-wire 2.5 mm² cable 2, 3, 5 or 10 m long, with an accuracy of 0.4 % at an error below 10 %. The TU40GI version is made in a plastic housing without potting. TU40RGV is a low-power transformer with a 225 mV output, class 0.2S, IP65 protection and a cable with an RJ45 connector (pins 1 and 2 are S1 and S2 respectively); the housing is filled with UL V0 polyurethane, and it complies with EN 61869-1, -2, -8 and -10. The RC coil gives 100 µV/A, class 0.5, linearity of ±0.2 % over the 10–100 % range at 50–60 Hz, and has double insulation, protection class II, 1000 V CAT III / 600 V CAT IV and pollution degree 2 under IEC/EN 61010-1 and 61010-2-32. TEH-132 has a Ø32 mm window, ratings of 100, 200, 300, 400, 500, 600 and 1000 A, ranges from ±300 to ±1500 A and an offset voltage below ±10 mV.
How to choose
For the neutral in a tight board, take TU40RGI, and for an electronic low-level signal input, TU40RGV at 225 mV. For large-section busbars without taking them apart, it is better to fit the RC coil, which works with the SAM3000, SAM3001 and AHM1-RC analyzers. DC current in UPS or solar systems is measured with TEH-132. For measurement at 5 A or 1 A, take the ordinary TU_ or TA_P.
