1. Distinguish Two Types of Current
1. Steady-state standby input current (unit powered on standby mode)
2. Instant peak inrush current during exposure (maximum current at radiography, core factor for UPS selection)
Device: 50kW digital DR X-ray machine, 3-phase 380V input, power factor of high-voltage generator cosφ≈0.8
(1) Formula for Rated Steady-State Input Current
3-phase current calculation formula:
I = \frac{P}{\sqrt{3}×U×cosφ}
Parameters: P=50000W, U=380V, cosφ=0.8
