HIOKI – 9278

The 9277, 9278 was developed for to provide a 20 A (9277), 200 A (9278) clamp sensor corresponding to AC/DC current.

The 9277, 9278 was developed for to provide a 20 A (9277), 200 A (9278) clamp sensor corresponding to AC/DC current. The 9277, 9278 makes it possible to measure AC/DC current in live power lines without cutting into the lines. The sensor features good frequency response (amplitude and phase), good temperature response (sensitivity and offset), and dielectric strength and is easy to connect and use. Its versatility will find application in a wide variety of fields dealing with current and power measurement.
