The SR634 is 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.
