Summary
The DC-DC converters of the SR series are power supply
modules for electronic systems. Their major advantages in-
clude a high efficiency that remains virtually constant over
the entire input voltage range, high reliability, low ripple and
excellent dynamic response. The converters are designed
for chassis mounting.
