DC/DC Converter TEL 8 Series, 8 Watt
Models
• Ultra compact 8 W converter in
DIP-16 metal casing
• Operating temperature range
-40°C to +80°C
• Wide 2:1 input range
• Fully regulated outputs
• Protection against short circuit
and overload condition
• Built-In EN 55032 class A filter
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 feature
a high efficiency of up to 86% which allows an operation temperature of up to
+70°C at full load. An internal 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.
