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.

For negative logic, add suffix "N" to model number.
MTBF predictions may vary slightly from model to model.
Specifications typically at 25C, normal line, and full load, unless otherwise
stated.
Soldering Conditions: I/O pins, 260C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please consult factory
for specific model information.
