When the mains supply is stable, the UPS5000-H mainly works in which mode after ECO is configured?
After ECO mode is enabled on the UPS5000-H, the system's control objective changes from ''always supply the load through the inverter'' to ''maximize efficiency while keeping protection mechanisms ready.'' When the mains input is within the configured ECO acceptance window (voltage, frequency, THD, and other quality thresholds), the UPS supplies the critical load primarily through the static bypass path, which has lower conversion losses than continuous double-conversion. The inverter remains synchronized and on standby, so if the mains quality deteriorates or an abnormal condition is detected, the UPS can rapidly transfer the load back to inverter operation to maintain output stability. Battery mode is only used when the rectifier/bypass source is unavailable or out of range, and maintenance bypass is a manual service path used for isolation during maintenance, not for normal energy-saving operation. Therefore, with stable utility power and ECO configured, the UPS5000-H mainly operates in static bypass mode.
