In House Certification Laboratory

Signal Transformer maintains an in-house ISO 17025 certified laboratory that enables us to participate in CSA’s Supervised Manufacturing Testing & Certification (SMTC) program. This program makes it possible to certify and use the CSA / cCSAus mark on new designs within days.

For more than 15 years, Signal Transformer has been able to both simplify and expedite the transformer Certification process for our clients by utilizing CSA’s SMTC Program. Most recently this prestigious program has undergone significant change. Manufacturers utilizing this program must now qualify to the IEC/ISO 17025 standard for Testing Laboratories.

What is the SMTC and why is it of significance to Signal and our customers? This program allows designated Signal Transformer engineering personnel to test and evaluate both catalog and custom transformers to CSA and UL transformer standards. Upon successful completion of tests, the results are supplied to CSA whereupon the CSA engineer reviews the results and grants Signal the authorization to “certify” the component. This process may require as little as 3 days after transformer samples are provided to Signal’s engineering department.

Signal Transformer is the only transformer manufacturer in the United States having such accreditation to the SMTC program. In addition, Signal Transformer’s engineering director is one of four registered Delegates on the United States National Committee, (USNC) Technical Committee, (TC) 96 for the International Electro-technical Commission, (IEC). National Committee Delegates have the responsibility and authority to revise and mandate changes to the relevant IEC standards.

While minimizing the costs and lead time associated with the certification of custom transformers. USNC Delegates represent the voice of US transformer manufacturers and have intimate firsthand knowledge of any pending changes and or revisions to the relevant IEC standards. Having this association allows Signal’s engineering staff to maintain vigilant standards oversight.
