ECV vs. EPV
 The electronic enclosure is the biggest difference between the ECV and the EPV. 
- ECV - NEMA-4X watertight enclosure sutiable for the harshest industrial environments
 - EPV - general purpose enclosure suitable for laboratory, commercial and OEM environments, where the EPV is installed inside of a larger machine
