TECH CORNER
1.
CONTROLLER:
The controller turns off power to the load at 11V and
reconnects when the battery reaches 12V. This protects battery from
over-discharge and increases battery life and performance.
2.
CAPACITY:
With a typical AP running 4W average. A single 12V
9Ah battery should be able to provide backup power for up to 24 hours
at room temperature. For cold temperatures the capacity is reduced by
20-30%.
3.
VENTING:
The enclosure is vented thru the wire feedthrus in the bot-
tom of the enclosure. Don’t make these airtight.
4.
DUAL INPUTS:
The UPS-DC can be used with solar power alone or
POE power alone or a combination of both.
5.
SOLAR PANEL:
The controller used in the UPS-PL can handle a
maximum panel size of 135W. Do not exceed 8A into the SOL input or
damage to the controller can occur. When the solar panel is generating
power, the SOL input will take priority and the POE input will not be
used to charge the battery. When the solar panel isn’t generating power
then the battery will be charged from the POE input.
6.
SOLAR PANEL ANGLE:
Solar panel angle should be adjusted to
optimize output. Optimum angle is based on location longitude and is
different if summer or winter. If the panel won’t have seasonal adjust-
ment, set for winter angle and leave this setting year round. See tycon-
power.com/learning_center for additional information. If you are plan-
ning to keep solar panel angle fixed all year then set the angle to
Your_Latitude * 0.9 +30
7.
BATTERY HOOKUP:
Always connect the battery first and discon-
nect the battery last. The controller should not be run without a battery
connected.
8.
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.
Note: Never store batteries for any length of time in a
discharged state or it will kill the battery.
9. 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 11V 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
them with a good quality 10A automotive battery charger. Once they
are back to a normal operating range, the integrated charge controller
will maintain the charge.

DUAL OUTPUTS:
The UPS-PL has a POE output which can be
