DC/DC Converter TEC 3 Series, 3 Watt

Models

TEC 3 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 low input range input is extended from 4.5 to 13.2 VDC while models are also

available with the standard 2:1 input ranges of 9-18, 18-36 and 36-75 VDC (see TEC 3WI series

for 4:1 input ranges). The functional I/O-isolation system is designed to meet IEC/EN 62368-1

with a test voltage (60 s) of 1600 VDC.
