Parameter Specification Notes / Explanation
Model F3RZ91-0F
Type AC/DC Current Sensor (Zero-Flux / Magnetic Feedback Type)
Rated Input (I_R) 50 A AC/DC The primary current that produces the rated output.
Maximum Input 70 A (AC peak / DC) The absolute maximum current that can be measured.
Output Voltage ±1.25 V (for rated input) A 50 A input will produce a 1.25 V output.
Ratio 40 A / 1 V (50 A in → 1.25 V out) The conversion ratio for instrument configuration.
Basic Accuracy ±0.05% of rdg ±0.5 mA (DC, 45-66 Hz) Extremely high accuracy, especially at DC and line frequency.
Frequency Bandwidth DC to 2 MHz (-3 dB point) Exceptionally wide range for both low and high-frequency analysis.
Phase Error ±0.1° (at 50/60 Hz) Critically low for highly accurate power and power factor measurements.
Output Connector BNC connector
Aperture Size 20 mm (0.79 in) diameter The diameter of the hole for the conductor.
Primary Conductor Fixed, internal This is a solid-body sensor; the conductor is inserted through the hole. It is not a clamp.
Safety Rating CAT II 600 V (300 V CAT III) Rated for measurements on electrical circuits.
Operating Temperature 0 °C to 50 °C (32 °F to 122 °F)
