We hereby inform you that we have made a minor hardware update to our TEC Controller TEC-1091.
Once the stock of the current HW v3.50 has been depleted, the new hardware version 3.51 will be delivered as standard starting in autumn 2025. The current hardware version 3.50 will still be available on request after autumn 2025.
The hardware update (from v3.50 to v3.51) is available immediately upon request but must be specified when ordering.
The following delivery schedule applies:
| Standard | Customer Request | |
|---|---|---|
| Until approx. October 2025 | v3.50 | v3.51 |
| From approx. October 2025 | v3.51 | v3.50 |
Important: Please specify your desired hardware version with every RFQ/order.
Hardware changes
For hardware version 3.51, additional filters have been added to further increase the robustness of the hardware. Due to the minor nature of the change, only the second subversion number is incremented.
The new hardware version is 100% software compatible with the previous version of the TEC-1091 and serves as a 1:1 replacement for older versions. We expect that you will not notice any difference compared to the current hardware version. All firmware versions from v3.20 onwards can be used with the new TEC-1091 HW v3.51.
For more information on the hardware update, please refer to the document TEC-Family Hardware Release Notes (PDF).
