DC/DC Converter
THI Series 2 Watt
The THI series is a family of dc/dc-converter with very high I/O-
Isolation specification. They are certified according to EN 60950
and IEC-60601-1 safety standards and offer a cost effective so-
lution 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.
