Isolation transformer certified to medical device safety standard IEC 60601-1 ed. 3.1.
In the manufacturing of medical devices and medical testing equipment, the most critical aspect of safety standards is the power transformer. By adopting this transformer, which has already obtained certification under the medical device safety standard IEC60601-1, the CB certification testing for the power transformer section is exempted, resulting in reduced inspection costs and shortened inspection periods. This transformer is manufactured as our general standard product.
