Product Description

Isolation conversion: Isolate the measured large current and convert it into a standard DC voltage signal with a linear proportional output to ensure safe and high-precision measurement. Temperature compensation circuit: Built-in temperature compensation circuit effectively controls the impact of temperature changes on measurement results and ensures consistency and stability under various environmental conditions. Low zero drift: Advanced design and manufacturing process are used to achieve extremely small zero drift to ensure measurement accuracy. Perforation input: Supports perforation input mode, easy installation and use, compatible with RVVP signal line, and simplified wiring
