DC/DC Converter
TED Series 2 Watt
The TED-series are high performance, isolated DC/DC-converters with
wide 2 :1 input range. They are ideally suited for distributed power
systems in telecommunications, industrial electronics and test equipment. Full SMT-design with exclusive use of ceramic chip-capacitors
guarantees very high reliability with a calculated MTBF of over 1Mil.h.
A highly automated production with 100% parameter test of each
converter ensures the high quality standard of this product.
