Rated Momentary Line Current (shorter than 5s):
• 30A (100V/110V/120V)
• 28A (200V)
• 25A (220V/230V/240V)
Rated Continuous Line Current:
• 20A (100V/110V/120V)
• 12A (200V)
• 10A (220V/230V/240V)
Maximum line impedance: 0.3 Ω |0.6 Ω |0.6 Ω
Max Line Regulation (Percent): 15% at maximum radiographic exposure.
Line regulation is based on measurements made at the input (primary winding) of the isolation
transformer under standby conditions and at maximum radiographic exposure by the following equation:
Line regulation = 100 (Vn - V1)/V1
Where Vn = no load voltage (standby), and V1 = loaded voltage (maximum radiographic exposure).
16A power supply is required in China. And 20 A is required in Japan.
Suitable sockets are required both in Scan room and Operating room for maintenance.
Power supply should comply with requirement of the system power supply requirements.
The sockets should be 3 cores with protective earth, which complies with the requirement
of the applicable electrical codes. Other equipment electrically connected with this
apparatus shares the same grounding connection.
You should check the local power supply first. If it is not 200 V/220 V/230 V/240 V (50 Hz),
you need change the power supply cables and change the connections of the system.
Refer to the Power Supply Adaptation section3.5.1 for details.
