Line Interactive UPS 850VA with AVR + USB port

  • TRUE AVR (Automatic Voltage Regulation)
  • Wide Input Voltage Range
  • Load Auto Sensing and Abnormal Protection
  • Fast Charging
PROLiNK® PRO851SFC is a single-phase input/ single-phase output Line-Interactive UPS system with PROLiNK’s latest Super-Fast Charging technology. This cutting-edge technology is able to recharge the battery back to 90% of its capacity within 2-4 hours, perfect for areas with intermittent power.
Advance Early Warning system immediately s you to an output overload, high temperature or low battery condition, giving you ample time to either correct the condition or shut down your system before battery time runs out.
Intelligent Battery Management system provides additional protection for battery overcharging or deep discharging, while maximizing battery performance, life and reliability through intelligent precision charging. In the event of over temperature and overload, the device will automatically shutdown to prevent any damage from occurring.
Lastly, this device is supported with a wide input voltage range. The unit also comes with universal sockets to provide better compatibility with a wider range of connected devices.
PRO851SFC(U) is an ideal solution for safe and stable backup power to home/ small office applications.
