HF Series X-ray Generators - Service Manual Revision W
Quantum Medical Imaging 1-15
GENERATOR AUXILIARY POWER SUPPLIES
The HF Series X-ray Generator supplies the following supply voltages for powering
X-ray room equipment:
• 24 VDC, 1.5A
• 24 VAC, 150W (collimator lamp not to exceed 150W)
• 115 VAC, 3A
NOTE: The above voltage outputs are not to be used as power
sources for collimator lamps or for inductive loads (e.g.,
motorized tables, solenoids, etc.)
PERFORMANCE SPECIFICATIONS
Table 1-5 provides performance specifications of single-phase (non-stored
energy) HF Series Generators.
* Time measured at 75% of the peak kVp waveform
NOTE: AEC TECHNIQUES SHOULD HAVE EXPOSURE TIMES EXCEEDING 8
MILLISECONDS.
