1.
CONTROLLER:
The controller turns off power to the load at 22V and
reconnects when the battery reaches 24V. This protects battery from
overdischarge and increases battery life and performance.
2.
CAPACITY:
The UPSPro UPS-ST2424-UBNT is rated at up to 30W
power output. If you exceed this load the system may not function to
expectations.
3.
VENTING:
The enclosure is vented thru the wire feedthrus and vari-
ous hole plugs in the bottom of the enclosure. Don’t make these airtight
with silicon
4.
BATTERY MAINTENANCE:
The batteries used in the UPSPro sys-
tems don’t require any maintenance. They should last up to 5 years in
normal use.
5.
BATTERY OVERDISCHARGE
: We highly recommend hooking all
equipment loads to the controller voltage output. This output will discon-
nect the load if the battery voltage drops below 22V and this will protect
the battery from over-discharge. If batteries get completely discharged
because the equipment was connected directly to the battery, you will
reduce the battery life and you will most likely need to supercharge
