Description
Technical Parameters
WBL551F47 (Micro-Current Measurement Detection Leakage Current Sensor) uses the phase-difference magnetic modulation principle to measure DC leakage current in the grid in real time. It converts the measured milliamp current signal into a standard tracking voltage (Ug) output. The sensor features high precision, high isolation, low drift, low power consumption, and a wide operating temperature range. This product is suitable for insulation resistance detection in DC grids and can also be used for small current detection.
