4. Functionality
The SEIGD50 operates as a current transducer that converts the magnetic field generated by an alternating current flowing through a primary conductor into a proportional voltage signal. The primary conductor passes through the central aperture of the device (Durchsteckwandler design), inducing a magnetic flux in the internal core. This flux is sensed by the internal winding and processed by the built-in electronic circuitry to produce a linear, isolated output voltage of ±5 V corresponding to the measured current.
Use Cases and Applications:
- Industrial automation and process control systems
- Power distribution monitoring and energy management
- Motor control and drive systems
- Renewable energy systems (solar inverters, wind turbines)
- Laboratory instrumentation and test benches
- Protection and fault detection circuits
- Building management systems (BMS) for load monitoring
Compatibility:
The ±5 V output signal is compatible with most analog input modules, data acquisition systems, programmable logic controllers (PLCs), and industrial monitoring equipment that accept bipolar voltage inputs. The ±15 V supply requirement aligns with standard industrial control power supplies.
