Current Transformers
Versatile current and voltage transformers
REO current transformers are particularly characterized by their compact design, excellent linearity, short response time, and low iron and remagnetization losses.
The WKO-2C-B current transformer with dual-core technology and Hall effect features an extended frequency range up to 120 kHz and precise phase response.
These current transformers guarantee an improved measurement accuracy of 0.5% across the entire frequency range: DC up to 120 kHz. Furthermore, they feature better drift compensation and an extended temperature range from -40°C to 85°C.
Customized for their specific application, they comply with DIN EN 50178 as a standard regulation.
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)
