Passive Current Transformer Series In-I
Pulse Current Transformers Description Due to the selected materials, REO pulse current transformers of the IN-I series can represent current with high accuracy and the corresponding transformation ratio – making them particularly suitable for power measurement, current monitoring and analysis, and for use in solar inverters. They are also ideally suited for use in active filters, as they can be designed for measuring current peaks. The primary current is measured via a current conductor that passes through the closed toroidal core. The magnetic field generated by the current flow through the conductor is absorbed by the toroidal core and, according to the transformation ratio of the secondary winding, generates a smaller current for measurement purposes. This method reduces a high measurement current to a significantly smaller current and additionally separates it from the primary circuit by means of safe galvanic isolation. Advantages Very precise current measurement Class 0.2 Pulse current measurement Low-loss core (core losses <10W/kg at 20kHz/200mT) Housing made of UL VO material (Conductor must be positioned) Diverse applications, e.g., for:Active filters, EMC measurements, and pulse current measurements Typical Applications Measurement and Testing Technology Technical data Type 50 100 200 Primary current [A] IPN r.m.s 0 – 50 0 – 100 0 – 200 Max.

The primary current generates a magnetic flux and this is evaluated by means of a magnetic circuit and Hall sensor in the air gap. The signal from the Hall sensor is processed by an electronic circuit and an exact representation of the primary current is output as a voltage. Advantages (electrical) Measurement of direct and alternating currents Voltage output Low power consumption No additional losses in the measuring circuit High-quality UL-listed insulating materials (e.g. UL94-V0 Safe electrically isolated primary and secondary circuits Good price/performance ratio Advantages (mechanical) Low weight Robust housing designs (for horizontal/vertical mounting) Connections: clamps, plugs, flat-cable plugs or cables Wide range of housings with various push-through openings Typical applications Industry, Renewable energy sources, Railway engineering, Energy, automation and building technology Technical specification Type 25 150 300 Primary rated current [A] ÎPN Peak 25 150 300 Max.
