I/O-isolation voltage 1‘600 VDC
Fully regulated outputs
Operating temp range –40°C to +95°C
Continuous short circuit protection
Remote On/Off
Designed to meet IEC/EN/UL 62368-1
(not certified)
TEC 2 is a new series with the design purpose to improve the prevalent 2 Watt
SIP-8 DC/DC converters in terms of cost, efficiency and performance. The latest technology and components enable an increase in efficiency by more than
20%. With the reduction of thermal loss, the operating temperature range can
be expanded from -40°C to +95°C. The converters are fully regulated over 0 100% load (no minimum load is required). The low input range is extended
from 4.5 to 13.2 VDC while models are also available with the standard 2:1 input ranges (see TEC 2WI series for 4:1 input ranges). The functional isolation
system is designed to meet IEC/EN/UL 62368-1 (not certified) with 1600 VDC
test voltage.
