HF Series X-ray Generators - Service Manual Revision W
Quantum Medical Imaging 1-7
NOTE: All single-phase x-ray generator input ratings assume the use of a
single-phase distribution transformer. When utilizing two legs of a 3-
phase transformer, review the National Electrical Code and any appli-
cable local electrical code(s) to ensure the correct rating distribution
transformer (in terms of KVA) is used to assure line stability. This
configuration would require an increase in the overall power (KVA) of
the distribution transformer, depending on whether the input line
transformer is Wye or Delta type. Under no circumstances should a
Delta type transformer be used for input power to a 3-phase genera-
tor.
SINGLE-PHASE X-RAY GENERATORS
Non-Stored Energy Single-phase x-ray generators require three-wire line inputs in
either of the following two configurations:
• one hot wire, one neutral wire, and one earth ground wire
• two hot wires and one earth ground.
Refer to Table 1-1 for power requirements of single-phase (non-stored energy)
HF Series Generators.
