The current transformer used as an internal transformer on a CR7310 is a reasonable size for an application of mine but the application, because it will require 12 modules and their current transformers in two compact groups (modules in one, transformers in the other) it really does need to use an external coil. The two external coils suggested for use with the CR7310 are much too big for this application. Can you suggest a smaller external coil, similar in size to the the internal coil, that would work with the CR7310?
