Zero Flux High Performance Current Sensor | IsoBlock I-ZF Series

Verivolt IsoBlock I-ZF Series
Zero Flux High-Performance Current Sensor

Precise Current Sensor for High-Current Measurements
The IsoBlock I-ZF Series is a compact current sensor designed for precise measurements up to 2000 A. Developed for industrial applications, energy engineering, and research, the system reliably captures current, voltage, and every relevant signal. The conditioned output is fully compatible with professional measuring instruments and integrates seamlessly into existing systems.

Reliable Power Measurement – from Source to Evaluation
In test benches and monitoring environments, the IsoBlock I-ZF Series provides the foundation for reproducible power measurements and transparent trend analysis. Clear signal processing ensures consistent results over long operating periods, supporting quality-driven decision-making in development, production, and service.

Closed-Loop Technology for Maximum Measurement Stability
Measurements are based on the Hall effect combined with closed-loop technology, ensuring fast response times, excellent linearity, and long-term stability. Captured signals are filtered and delivered in an optimized output format, allowing measurement chains in laboratories and field applications to be mapped identically—from power supply to data acquisition.

Galvanic Isolation – Maximum Safety and Noise Immunity
The IsoBlock I-ZF Series features full galvanic isolation. The separation between primary and secondary sides protects sensitive electronics from interference, prevents feedback, and enhances operational safety. In battery testing and demanding electrical systems, carefully engineered isolation—supported by reliable isolators—ensures stable measurement values even under dynamic conditions.

Easy Installation, Fast Integration
The modules can be mounted on standard DIN rails for quick and simple setup. The IsoBlock I-ZF Series combines precise current and voltage measurement with high reliability and efficient commissioning—an ideal solution whenever power must be continuously and reliably monitored.
