Highest Precision DC Current Transducers

These advanced current transducers enable precise measurement of DC, AC, and pulsed currents while ensuring galvanic isolation between the potent primary circuit and the electronic secondary circuit.

Achieving <1 ppm linearity and accuracy, the EZF series relies on zero-flux technology. These products facilitate precise monitoring of DC and AC currents, featuring high bandwidth, minimal temperature drift and remarkably low noise.

Additionally, the transducers address magnetic remanence issues through an incorporated degaussing function. Although this process is typically executed during device start-up, it can also be manually initiated.

These are the ideal solution for power supplies, biomedical devices, Nuclear Magnetic Resonance (NMR), calibration systems test and measurement and power-electronics applications requiring high performance accuracy, drift and response time.
