UD33 series Online UPS adopts flexible weaving technology and is often used in Industrial Power Supply. In power systems, AC and DC power supply systems are usually required to ensure good isolation, so UPS systems are required to have output isolation transformers. Because the 220V input voltage of the DC bus cannot get 220V AC output after passing through the SPWM inverter, the output isolation power frequency transformer is used for boosting and then outputting. It includes power 20KVA/20KW, 30KVA/30KW, 40KVA/40KW, 60KVA/60KW, 80KVA/80KW, 100KVA/100KW, 120KVA/120KW, 160KVA/160KW, 200KVA/200KW.
