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
