Description

Backup of DC12V/24V devices in the event of momentary voltage drop or power failure

Powerful specification of 12V 5A / 24V 3A (44.4WH or 88.8WH) achieves over 30 minutes power outage retention time (at rated maximum current).
It is ideal as a power supply for communication equipment, security cameras, wireless equipment, broadcasting equipment, etc.

feature

  • Can be charged from a commercially available 12V AC adapter
  • Small size, powerful output
  • Preferentially distribute current to loads after power failure recovery with constant charging current
