High Precision DC to 20 kHz/500A AC/DC Current Sensor with ±0.5% Accuracy
Hioki AC/DC clamp sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The 9279 is a DC to 20 kHz/500A sensor, ideal for monitoring waveforms of switching power supplies, inverters, power conditioners, etc.
Not CE Marked
Model 9279 cannot be used alone. The 9555-10 Sensor Unit must be used when connecting the probe with a Hioki Memory HiCorder. Model 9279 can be connected directly to Models 3193, 3193-10, 3194 and 3390 power measuring devices.
Wide DC to 200 kHz frequency bandwidth
• Minimal zero drift for stable, long-term measurements
• For power lines and secondary side of inverters
• 650A of continuous input
• Use together with the SENSOR UNIT 9555-10 for high precision waveform monitoring and recording
• Also pair with AC/DC clamp on power meters
