AEMC SR634 Description:
This a general purpose 1000AAC current probe designed for use with instruments that require a 5A current input. It works as a traditional current transformer (with ratios of 250:5, 500:5 or 1000:5) and has an output of 5mA per amp measured in the jaw. The SR634 has jack output termination that accept 4mm banana plugs. The rounded jaw design on this probe makes it well-suited for power applications where high accuracy and low phase shift is important.
Features
- Measurement range of 100mA to 1200AAC
- Large jaw opening accommodates conductors up to two 500kcmil
- Improved ergonomic design and easy operation
- Conforms to EN 61010, 600V CAT III
- Low phase shift for power measurement
- Designed for DMMs, recorders, loggers, oscilloscopes, power and harmonic meters
Applications
- Power quality measuring
- Large industrial loads
- Measuring around cable bundles
- Power load monitoring
- Waveform analysis
