Hioki Clamp on Sensor 9661

500A Voltage Output Sensor for Current Load Measurements

Hioki current sensors are best-in-class devices for use with power meters, PQAs and Memory HiCorders. The 9661 is a 500A AC voltage output clamp sensor for measuring large load current.

Note: Supports power quality analyzers, power meters and other data acquisition equipment with voltage input

For inverter equipment or commercial power lines
• Measure up to 550A AC continuously

Basic specifications (Accuracy guaranteed for 1 year)

Note: In addition to the Power Quality Analyzer, can also be used as a current sensor with HIOKI's power meter and voltage input recorders.
