1 Overview
The Model XPPS X-ray Preamplifier Power Supply from
XIA provides low-noise linear DC power to run x-ray and gamma-ray
preamplifiers. The XPPS provides 24V and 12V on four industry-
standard DB-9 connectors, and is specifically designed to provide
power for multi-element x-ray detectors used at synchrotron beamlines.
The XPPS is designed to power 50 or more preamplifier channels,
based on the published preamplifier power needs for the most popular
detectors. The 12V supplies produce 5.1 amps each, while the 24V
supplies each produce 3.6 amps. Test points are available on the front
panel to measure the voltages. A thick ground strap is provided to make
a strong ground connection to the signal processing electronics in order
to reduce possible ground loop noise.
1.1 XPPS Features
