Hi All,

We have 3 units of Galaxy 5000 100KVA in Parrallel redundant set up, "PFC Fault" is giving us lot of trouble as UPS forced to bypass.Could you share some assessment with this PFC Fault experienced?

Many Thanks for the advanced input.

No a PFC fault will most likely require a trained technician.

hello,

i asked someone who supports this unit and they told me:

Possible reasons for (PFC fault) :

a. Input source out of tolerance
b. Open input power fuse
c. Faulty CSNEN/CSNON module including SCR
d. Faulty DCHEN/DCHON
e. Faulty MIZNUS PCA
f. DC capacitor shorted

beyond that, i'd probably advise that you contact your local support to see which issue you may be seeing specifically and how to address it.

btw, can we correct the fault by ourselves? thru configuration?

Thanks,E
