The TEN
12 series of DC/DC converters has been designed for a wide range
of applications including communications, industrial systems and battery pow-
ered mobile equipments. Key features are high power density (12W in a
2“x1“x0.4“ package) and ultrawide input ranges of 9–36 VDC and 18–
75 VDC. Other features of this converter are internal filtering according to
EN 55022, level A, safety approval to EN 60950 and UL
1950, wide oper-
ating temperature range and remote on/off (opt.).
