The TEL 5 Series is a range of DC/DC-converter modules with wide input range
of 2:1. State of the art SMD-technology guarantees a product with very high reli-
ability and excellent cost /performance ratio. High efficiency allows an operating
temperature range of –40°C to +85°C at full load. This product series provides an
economical solution for many cost critical applications in industrial and consumer
electronics.
