CAPACITY:
The UPSPro UPS-ST12 is rated at 144W load output.
The UPS-ST24 is rated at 192W load output. The UPS –ST24 can de-
liver 288W to the load but then the power available for battery charging
is too small, so we recommend not to exceed 192W to the load for best
performance.
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 the set voltage and this
will protect the battery from over-discharge. If batteries get completely
discharged because the equipment was connected directly to the bat-
