Description
The topology is VFI-SS-111 online per IEC 62040-3 with output PF 0.9, so it delivers fewer watts than the VA on its nameplate. Input PF is above 0.99. On a 220/230/240 V nominal supply it stays off battery across 140–276 V. Besides ON LINE it runs in ECO, SMART ACTIVE, STANDBY OFF and frequency converter modes, and efficiency reaches 98 % in ECO and SMART ACTIVE. It carries 125 % overload for 5 s and 150 % for 1 s, so loads with heavy inrush do not belong on it. Cold start from batteries works when the mains is down. The SER 3000 ER model ships without internal batteries and with a 6 A charger, while the others come with VRLA AGM. The UPS complies with IEC/EN 62040-1 and IEC/EN 62040-2.
How to choose
Size by real power, comparing the load in watts with the 1,500 or 3,000 VA rating multiplied by 0.9. If long runtime is needed, choose the SER 3000 ER with external batteries. Switches and routers that do not require double conversion can run on a line-interactive Vision Rack at 800 or 1,100 VA. The simplest rack option, the iDialog Rack at 600 and 1,200 VA, uses the standby VFD topology.
