Dear Valued Customer,

We are contacting you today to notify you that we plan to Increase the Max Input Voltage on TS-TPC-7990. Technologic Systems services many industries with our products and several customers have requested a higher maxim DC Input Power Voltage be allowed on the TS-TPC-7990 Product family.  The new maxim DC Input Power Voltage will be 36V, this change will roll out over the next 2 months.

The affected products are: TS-TPC-7990

As the BOM change is minor and should have no impact on other applications we will be updating the BOM to increase the TVS protecting the input voltage to be 36V tolerant.  TVS8 will transition to Littelfuse PN SMBJ36A

Please contact us before Apr 02, 2019 (4 weeks from now) if you have any concerns so that we can plan appropriately.

Technologic Systems appreciates your business. If you have further questions or concerns, please contact us by either replying to this email or filling out the contact us form at

Best Regards,
