X-ray

1. When adding up voltage, total current is less than 2a and total power is 500w; 2. The current and voltage of x-ray tubes are fixed in three groups, they are: X exposure voltag (kvp) 60 65 70 X-ray current (ma) 0.5 0.85 1.10 3. When adding up voltage, total current is less than 2a and total power is 500w 4. Drain current and earth resistance are in accordant with the stipulates in gb9706.1 5. The three groups of voltage (60kv, 65kv, 70kv) are adjustable. 6. Wireless remote control in any angles within 10 meters part form the control box 7.
