TECHNICAL SPECIFICATIONS
QAS DC/DC converters are designed to provide
higher output voltages for telecom and industrial
applications. The QAS features remote sense for
accurate point of load regulation, five-sided shielding,
and 1500 VDC isolation. The QAS also provides
output voltage trim, overcurrent, short circuit, and
overvoltage protection, allowing use in a wide range of
applications.
