Description
SRBC-16A2Ax modules series non-isolated dc/dc converters that deliver output current with full load efficiency output. These modules provide precisely regulated voltage programmable external resistor from 0.75 over wide range input voltage (8.3 Vdc). These modules have sequencing feature that enables designers implement various types output voltage sequencing when powering multiple voltages board. open-frame construction small footprint enable designers develop cost space-efficient solutions. Standard features include remote On/Off, remote sense, over current protection, short current protection, wide input, programmable output voltage.
