Unit Product Code may be prefixed by K, SP followed by / or -
For units with non-safety related changes eg. Reduced OVP, current limit etc.
Unit product code is followed by "-NNNNL", where N is a string of numbers which identifies the unique
requirement. And L is a letter, starting with "A", which is incremented for any customer revision.
Example: CUS400M-24/FE-0001A
For non-standard units:
Prefix with "K". Follow by basic model type eg. CUS400M. Followed by "-NNNNL", where N is a string of
numbers which identifies the non-standard requirement. L is a letter, starting with "A", which is incremented
for any customer revision.
Example:
KCUS400M-24-0001A
