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 (12 W in a
2"x1"x 0.4" 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.).
