①SC5000UD-MV-US and DCDC form a two-level system application, and the working DC
bus voltage range is [1300~1360]V. SC5000UD-MV-US is capable of working at 1500V.
②All models support single-branch and multi-branch designs (Max. 10 branchs).
SC5000UD-MV-US mainly promotes multi-branch design and others mainly promotes sin-
gle-branch design.
③The maximum output apparent power of 100% overload can be met when the AC voltage
is rated and above. The power is limited according to the maximum current below the rated
voltage.
④The maximum current of 100% overload can be met when the AC voltage is rated and be-
low. The current is limited according to the maximum power above the rated voltage.
13.2 Tightening Torques
Tighten the cable with proper torque shown below to prevent the poor contact, high contact
resistance, or fire caused by the looseness of cable lugs:
Screw size
Torque(N.m) Torque(lbf.inch)
M3 0.7~1 6.195~8.85
M4 1.8~2.4 15.93~21.24
