Portage Electric Products, Inc. (Pepi®)
Standard Marking System

Portage Electric Products Standard Marking System lets you easily identify the information you need to know for our thermal controls.  The Standard Marking System provides important information for the manufacturing location, the week and year of calibration, termination options, the nominal calibration temperature, and the calibration tolerance. 

As Portage Electric has manufacturing facilities around the world, the Standard Marking System has been revised to include a Location Code to provide information as to where your thermal controls were manufactured and what location any termination options were performed.  Due to Pepi consolidating manufacturing assets, the location where the thermal controls were manufactured and the location where optimal lead termination is applied may vary.  Please see the included table which provides for all possible scenarios.
