Active and passive current transformers
Heavy-Duty Current Transformers from REO
Diverse current and voltage transformers
REO current transformers distinguish themselves primarily due to their low space requirements, excellent linearity, short response times and their low iron und hysteresis losses. The WKO-2C-B current transformer with double-core technology and hall effect has an extended frequency response up to 120 kHz and an accurate phase response. The current transformers guarantee an improved current measurement accuracy of 0.5% in the whole frequency range: DC up to 120 kHz. They also have improved drift compensation and an extended temperature range of -40°C to 85°C. They are also adapted perfectly to the corresponding operation site and meet DIN EN 50178 standards.
Benefits of current transformers
- Safe electrically isolated primary and secondary circuits
- High current measurement accuracy
- Non-critical with overload currents
- Ultra reliable
- Tough enclosure designs (horizontal or vertical mounting) with different variants for pushthrough openings
- Variable connections (clamps, plugs, flat-cable plugs, cables, etc.)
- Vibration and shock tested as per DIN EN 61373 Category 1 Class B (only for WKO and WDI types in AT enclosure)

Heavy Duty Catalog
Particularly resilient REO components at a glance
With the new Heavy-Duty catalog, you have for the first time all REO components that meet the highest requirements, clearly arranged and modern at a glance. These include chokes, transformers, resistors, current transformers and complete solutions. In the case of complete solutions, the main focus is on the highly compatible support frame system, the REOFLEX Multiuse Frame. Thanks to the standardized support frame, rail components from REO can be mounted easily, quickly and very variably. For safe damping and suspension, vibration dampers can even be integrated into the unit as required.
Customized product development
Individual product development at REO means achieving and maintaining parameters tailored to the customer’s needs, which would not be possible with standard products. Both the electrical parameters and the mechanical, constructive conditions are adapted. Thus, the customer receives exactly the product he needs for his application.
REO is not only a mass producer, but is particularly at home in the development and production of special niche solutions. In close cooperation with our customers, we develop ideas and technical solutions in small or large quantities, which, through their use in an overall system, take over tasks that are not covered by standard products on the market. In this way, we enable our customers to use state-of-the-art applications and innovative production processes without having to resort to standard products with limitations.
