I currently have a Liebert PSA700-230 UPS System, and for some reason I do need to change its output frequency.
- Are there any possibilities to change the cycle frequency of my UPS from 60Hz to 50Hz? I'm in Australia and the mains' frequency is 50Hz.
- The UPS utilize a microcontroller from MicroChip, PIC16C72A-20. Is it possible to re-program the PIC? I cannot do the programming bit, but will certainly be able to just flash it, anyway.
Thank you in advance, folks! Angga RF
