Table 19 External Power Supply Requirements - Varex Imaging Azure 3131Z Manual

During initial power up, the X-ray detector's internal DC-DC converters
present a low impedance load, and it is therefore important that the power
Note
supply can maintain its limiting current without voltage drop.
Ripple and Noise should not go beyond (20Mhz bandwidth) < 150 mVp-p.
Note
If power supply exceeds ripple and noise specifications, image artifacts may
occur.

a. The detector is supplied with a single voltage and uses internal, isolated DC-DC converters to generate the different
voltages necessary to run the detector.
b. Measured at the input of the detector.
c. The 15V minimum voltage needs to be maintained during configuration of the detector. The voltage drop across the power
supply cable must be taken into account when designing a power supply and power cable for the detector.
d. During initial power up, the detector's internal DC-DC converters present a low impedance load, and it is therefore
important that the power supply can maintain its limiting current without dropping below the lower voltage specification.
