Description
240 V HVDC and
380 V HVDC
power input ports
Protection components must be provided for PDFs to ensure that the rated HVDC
current of each channel is not less than 14A.
The input circuit breakers of a PDF must match the output circuit breakers.
In HVDC application scenarios, ensure that the protection components meet HVDC certification and the
fuses and circuit breakers meet positive and negative pole protection.
If the front-end PDF does not provide enough power inputs, configure a PDB that meets
the following requirements:
− The current of each channel output by the HVDC PDB is not less than 14A.
− Double-channel backup is used.
− The input current is not less than the sum of current of its connected output lines.
