The TEL 8 series is a range of isolated 8 Watt converters which come in a very
compact DIP-16 metal package. They offer a 2:1 input voltage range and fea-
ture a high efficiency of up to 86% which allows an operation temperature of
up to +70°C at full load. An input filter makes the converters comply with con-
ducted emission EN 55032 class A.
The TEL 8 Series models are an economical solution for space critical and cost
sensitive applications in instrumentation, IT and industrial electronics.
