Description
Hioki Clamp On Sensor 9669 for Accurate 1000 A AC Measurements
The Hioki Clamp On Sensor 9669 is engineered for high-capacity AC load current measurement, making it ideal for industrial and commercial power monitoring applications. Rated at 1000 A AC, this sensor provides precise readings with voltage output for power meters, PQAs, and other data acquisition devices.
Power Meters and PQAs
This sensor outputs 0.5 mV per ampere, allowing seamless integration with instruments that measure and record load current. The high-permeability core and magnetic shielding ensure accurate measurement of large currents without signal distortion.
Industrial Applications
Designed for large conductors up to 55 mm in diameter and bus bars of 80 × 20 mm, the Clamp On Sensor 9669 is ideal for inverter testing, commercial power monitoring, and industrial load analysis. Its compact and lightweight design allows easy installation even in constrained spaces.
High Accuracy Measurement
With amplitude accuracy of ±1.0% and phase accuracy of ±1°, this sensor performs reliably over a wide frequency range of 40 Hz to 5 kHz. Continuous operation at up to 1000 A ensures stable monitoring in demanding electrical systems.
Reliable Field Use
Operating in temperatures from 0°C to 50°C and relative humidity up to 80%, the sensor is suitable for typical industrial and commercial environments. The 3-meter cord and BNC output terminal allow flexible connectivity to measurement devices, making it an essential tool for engineers and technicians handling high-load currents.
