High-precision Current Testing
Description
Hioki’s clamp type AC/DC current sensors can be connected directly to Hioki Power Analyzers and Memory HiCorders.
Also, it can be connected to Power Meters, Oscilloscopes, DMMs, etc. by using an optional sensor unit.
Use with an instrument with a high input impedance of 1 MΩ or higher.
Key Features
- Frequency bandwidth DC to 200 kHz
- Rated current 500 A AC/DC
- Power supplied via the measurement instrument (when connecting Hioki Power Analyzer or Memory HiCorder)
- Ideal for use in environmental testing with broad -40°C to 85°C temperature range
- Ideal for EV inverter evaluation and PV power generation PCS evaluation
- Single-handed operation and robust locking mechanism
