Product Introduction
| MEWOI1178BE AC/DC clamp leakage current transformer, suitable for online detection of AC/DC current and leakage current with high precision below 600V, measuring range: AC/DC 0mA~50A, corresponding output AC/DC 0~600mV, jaw size 16mm x 18mm. The transformer adopts a clamp-shaped CT structure, which can be measured without disconnecting the measured line. The slender clamp head is especially suitable for places with dense wiring. The permalloy iron core is used, which has strong anti-interference ability and ensures the accuracy of measurement. and stability. It adopts non-contact measurement method, which is safe and simple to operate, and can be connected to industrial control devices, data recorders, oscilloscopes, high-precision digital multimeters and other equipment. |
