text: <s>[INST] MV Softstarter EDIT: moved to Drives and Motion community -FL Hi, wondering what the difference is between 1562E and 1562F. Thanks Terence [/INST] The 1562E was based on the SMC-Flex soft start controller, adapted to Medium Voltage. When we redesigned the MV soft starters to use the new SMC-50 based controller, the series number was changed to 1562F. There are numerous improvements and additions to the controller with the SMC-50, too many to list here. But suffice to say it does everything the SMC-Flex did, plus more. The power structure remains the same. \\n </s>
