X-ray Preamplifier Power Supply

The X-ray Preamplifier Power Supply (XPPS) provides power for 50 or more preamplifiers. The 19-inch rack-mount or benchtop unit contains linear power supplies that generate +/-12V @ 5.1 Amperes and +/-24V @ 3.6 Amperes, with very little noise. A rear panel ground strap is provided to eliminate ground loops, and should be connected to the PXI crate chassis. Four front panel DSUB-9 connectors share the total current available from each voltage according to the NIM standard pinout.
