Contact SupplierHigh frequency on-line double conversion technology
● DSP (Digital signal processors) control technology
● Active power factor correction (APFC), input power factor up to 0.99
● Output power factor 0.9
● Wide input voltage range (110V ~ 300Vac) and frequency range (40 ~ 70Hz)
● Auto sensing frequency
● 50/60Hz frequency conversion
● Cold start
● Rear ventilation design and variable speed fan
● Effective software and hardware protection
● Quick and stable charging, 90% capacity restored in 3 h (standard model UPS)
● Linear derating in low voltage input reducing battery discharging times
● Settable delayed start when power is restored
● Advanced battery management (ABM)
● Multiple functions settable via LCD: output voltage, EOD, auto-start, bypass mode, ECO mode and frequency conversion mode
● Multi-platform communications: RS232 (standard), USB / RS485 / SNMP / dry contacts (optional)
