TEC 3WI is a new series with the design purpose to improve the prevalent 3 Watt SIP-8
DC/DC converters in terms of cost, efficiency and performance. The latest technology and
components effectuate a high efficiency for a low thermal loss. This enables an operating
temperature range from -40°C up to +90°C. The converters are fully regulated over 0 -
100% load (no minimum load is required). The models are available with ultra-wide input
ranges of 4.5-18, 9-36 and 18-75 VDC. The functional I/O-isolation system is designed to
meet IEC/EN 62368-1 with a test voltage (60 s) of 1600 VDC.
