The SMT30C series is a new high density open-frame, non-isolated converter for space
sensitive applications. SMT30C has a wide input range of 10.2 Vdc to 13.8 Vdc and offers a
wide 0.9 Vdc to 5.0 Vdc output voltage range with a 30 A load. An external resistor adjusts the
output voltage from its pre-set value of 0.9 V to any value up to the 5 V maximum. Typical
efficiency is 91%. The series offers remote ON/OFF and over-current protection as standard.
With full international safety approvals including EN60950 and Ul/cUL60950, the SMT30C
reduces compliance costs and time to market.
All specifications are typical at nominal input Vin = 12 V, full load at 25 °C unless otherwise stated

Output Voltage Adjustment of the SMT30C Series
The ultra-wide output voltage trim range offers major advantages to users who
select the SMT30C. It is no longer necessary to purchase a variety of modules
in order to cover different output voltages. The output voltage can be trimmed
in a range of 0.9 Vdc to 5.0 Vdc. When the SMT30C converter leaves the
factory the output has been adjusted to the default voltage of 0.9 V.
