Backup Power Supply
Backup Power Supply
The Backup Power Supply provides power supply to repeaters in case the main power supply is cut. It can maintain the repeater working via stable DC power supply for up to 4 or 8 (or above) hours to ensure the normal running or cellular network.
With the IP65 casing and lightning-proof power module, the backup power supply can work outdoors under raining and lightning weathers.
