HF-525Plus Installation, Operation and Service Manual
5.5 Electrical requirements
■ This generator contains advanced circuitry which will maintain the selected X-ray values during
irregular input voltage condition. If input voltage condition is over or less, then could not get a good
X-ray radiation and have a good electric facility to be supplied with good regulation condition.
■ Supply specific electric power to the system.
√ Do not under size distribution transformer.
√ Insure the suitable electric facility for the system.
■ Generator Power line requirements.
√ Power line voltage variation must not exceed ± 10%.
√ Maximum line regulation for the maximum kVA demand is 10%.
