DC/DC Converter

TMV-EN Series 1 Watt

2 Year Product Warranty

The TMV-EN series are dc/dc conver ters with supplementary high
I/O-isolation, to comply with safety standard IEC/EN 60950.
They are designed for applications where approved isolation is
required, i.e. information technology equipment or medical equip­ment. SMT-design and a special transformer technology made it
possible to build these converters in a ver y small SIP-package, re­quiring a minimum space on the PCB.
