Question about APC Back UPS 650 (APWBK650MC) UPS System
OK APC 3000WAT
OUTPUT IS SAFE BUT WHEN BACK UP OCCURS
FROM 220V TO UPS THE OUTPUT BECOMES TO ZERO ALLOF RELAYS IS SAFE
ONE RELAYS BLINKS OFF AND ON
Your inverter is blown on the ouput. If it is a 300VA get a new one, 3000VA, you will need a local UPS repar company.
