The AEMC SR634 is a versatile 1000 AAC current probe designed for use with instruments requiring a 5 A current input. It functions as a traditional current transformer with ratios of 250:5, 500:5, or 1000:5, providing an output of 5 mA per ampere measured at the jaw. The probe features a large, rounded jaw capable of accommodating conductors up to two 500 kcmil cables. It includes a jack output compatible with 4 mm banana plugs, offering improved ergonomic design and ease of operation. Conforming to EN 61010 standards and rated for 600V CAT III, it ensures high accuracy and low phase shift, making it suitable for power quality measurement, industrial load monitoring, waveform analysis, and applications involving power and harmonic meters.
