The TEL 8WI series is a range of isolated 8 Watt converters which come in a
very compact DIP-16 metal package. They offer an ultra wide 4:1 input voltage
range and feature a high efficiency of up to 86% which allows an operation
temperature of up to +70°C at full load and up to 80°C with 50% load. The
converters have an internal input filter to comply with conducted emission
EN55022 class A.
The TEL 8WI Series models are an economical solution for space critical and
cost sensitive applications in instrumentation, IT and industrial electronics.
