We are constantly improving our products and have developed a new hardware version of the TEC-1091. The version 3.30 is being replaced by the new and improved version 3.40. We expect that you will not notice any difference.
The delivery of the new version will start at the beginning of July 2022.
Most significant changes made:
- Added snubber circuit to the power stage
- Reduced size of white orientation marker
- Changed filter capacitors of internal supply voltage measurements to 10nF
The new HW version is 100% software compatible with the previous TEC-1091 version and can be used as a 1:1 replacement for the older versions. All firmware versions starting from v3.20 can be used.
You can find more detailed information in the Hardware Release Notes.
If you want to have any further questions don't hesitate to contact us, we will be happy to provide further assistance.
Best regards,
Meerstetter Engineering Team
