(Example 1)
The power supply unit satisfying the total of the rate output and the maximum momentary output is
MDS-DH-CV-300.
Required power supply capacity (kVA) = (29.35 / 30) x 43 = 42.0 (kVA)
(Example 2)
The power supply unit satisfying the total of the rate output and the maximum momentary output is
MDS-DH-CV-370.
Required power supply capacity (kVA) = (26.2 / 30) x 43 = 37.6 (kVA)
(Example 3)
The power supply unit satisfying the total of the rate output and the maximum momentary output is
MDS-DH-CV-370.
Required power supply capacity (kVA) = (21.75 / 30) x 43 = 31.2 (kVA)
