Current transformers
Versatile current and voltage transformers
REO current transformers are characterised in particular by their small space requirement, excellent linearity, short response time and low iron and remagnetisation losses.
The WKO-2C-B current transformer with dual-core technology and Hall effect has an extended frequency response of up to 120 kHz and an accurate phase response.
The current transformers guarantee an improved measurement accuracy of 0.5% over the entire frequency range: DC up to 120 kHz. They also have better drift compensation and an extended temperature range of -40°C to 85°C.
Specially adapted to the respective place of use, they fulfil the DIN EN 50178 standard.
Advantages of current transformers
- Safe, electrically isolated primary and secondary circuits
- High current measurement accuracy
- Non-critical for overload currents
- High reliability
- Robust housing designs (horizontal/vertical mounting) with different variants for push-through openings
- Variable connections (terminals, plugs, flat plugs, cables, etc.)
- Vibration and shock test in accordance with DIN EN 61373 category 1 class B (only for WKO and WDI types in AT housing)
