Models
The THI 2 series is a family of dc/dc converter with very high I/O isolation speci-
fication. They offer a cost effective solution for all industrial, telecom and medical
applications where a supplementary insulation is required. SMD technology and a
100 % production test of the safety barrier ensure a very high reliability of this
product.
