The THI 2M series is a new range of ultra-compact 2W DC/DC-converters providing
a high I/O-isolation voltage of 3000 VAC. With a reinforced I/O-isolation system
this product is an economical solution for many applications in instrumentation,
industrial controls, medical equipment and everywhere where supplementary- or
reinforced insulation is required to meet requested safety standards.
Full SMD-design with exclusive use of ceramic capacitors ensure a very high reli-
ability and a long product lifetime.
