for Copeland Scroll Compressors.
3-Phase.
CoreSense AC software compatible.
NOTE:
These don't come in any "original packaging" as they never had any.
They come pre-installed on all tandem compressor sets.
I remove them and install our own modules leaving these as surplus.
If you'd like a manual let me know i can send you the PDF for these if it helps.
I can also answer any questions you have about these modules
