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. Benefits 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. primary current [A] ImaxPN r.m.s ± 60 ± 120 ± 240 Secondary current [mA] IaN r.m.s 0 – 50 0 – 100 0 – 200 Power [VA] Psek 0,5 1,0 1,5 Transformation ratio KN 1: 1000 1000 1000 Burden resistance [Ω] RB 200 100 37,5 Burden voltage [V] URB r.m.s 10 10 7,5 Measurement accuracy 50 Hz [%] FU ± 0.2 ± 0.2 ± 0.2 Ambient temperature [°C] TA -20 to +70 -20 to +70 -20 to +70 Frequency [Hz] f 0.050 to 50 0.050 to 50 0.050 to 50 Insulation test voltage Primary / Secondary / 2 sec [kVac] VP r.m.s 50 Hz 3 3 3 Storage temperature TS -25 to +85 -25 to +85 -25 to +85 Coil resistance RS @ TA = 25°C 11,5 11,5 9 Weight m 0,270 0,270 0,270 Standards EN/IEC 61869-1/2 Tracking resistance Housing / Casting resin 550 / 600M Creepage distance dCp 10 10 10 Clearance distance dCI 9 9 9 Datasheet All data and configurations can be found in our product datasheet.

Passive Current Transformers Series IN-D
Differential current transformer Description The residual current transformer makes it possible to measure the residual current on single-phase or three-phase supply cables or individual lines. Both current-carrying conductors (forward and return conductors) are fed through the current opening of the current transformer. The current is measured by comparing the forward and return conductors. Any deviation is displayed at the output of the residual current transformer. Due to the use of highly permeable materials, a typical current deviation from 10 mA is given. The large opening allows the supply lines to pass directly through over a wide area, with the exception of the protective conductor. Due to the high current sensitivity, evaluation in several stages is possible: stage 1: Notice of a malfunction stage 2: Alarm stage 3: Switching off Benefits The measurement from 25 to 400 Hz Nanocrystalline core Transformer for measuring differential current High-quality UL-listed insulating materials (e.g. UL94-V0) Safe electrically isolated primary and secondary circuits Robust housing designs (for horizontal/vertical mounting) Variable connections Wide range of housings with various push-through openings Residual current range 2 – 50 A Typical applications Industry, Renewable energy sources, Metrology and testing techniquesEnergy, automation and building technology Technical data Type 2 4 8 29 30 40 30 40 50 Housing A Housing B Housing C Primary rated current [A] IPN 0,1 – 1 0,1 – 2 0,1 – 4 0,1 – 10 0,1 – 10 0,1 – 10 0,1 – 10 0,1 – 10 0,1 – 10 Max.
