Current Share
Current Share ensures that the total output power of the power system is evenly shared
between all rectifiers.
Equalize
Equalize charges batteries at a higher voltage after they have been fully charged to ensure
that all individual cell voltages are the same, that electrolyte is distributed evenly, and that
sulfate crystal buildup on the plates is reduced.
Equalize can be scheduled to occur at regular intervals and/or can be started/stopped
manually.
‡
Refer to the battery manufacturer's instructions before using Equalize.
‡
If a Digital Input has the function "Start Equalize" then a manual equalize cycle will be started
when the Digital Input is active.
SM65 version 4.04 or later: If Equalize cannot start at the scheduled time (for example when
there is no AC supply) then its state will be Pending and it will start as soon as conditions
allow.
Fast Charge
After an AC power outage, Fast Charge automatically increases the float voltage of the
power system to recharge the batteries as quickly as possible.
Enable Fast Charge if the site experiences frequent AC power outages.
‡
Fast Charge does NOT function during a Battery Test, Equalize or if the battery current sensor
fails.
‡
If Fast Charge is used then Battery Current Limit (BCL) should also be used. See Battery
Current Limit on page 51 for details.
Load Based Rectifier Shutdown
Load Based Rectifier Shutdown (LBRS) automatically shuts down rectifiers when the total
load current is significantly less than the total rectifier capacity.
This raises the average load on the remaining rectifiers which will then operate at a higher
efficiency. This results in a decrease in total power consumption.
‡
Rectifiers shut down by LBRS will have the
<
(red) alarm LED on.
‡
Rectifiers shut down by LBRS can be temporarily restarted from the SM65 keypad or DCTools
using the Rectifier Restart function. See details on page 15 .
‡
LBRS is not compatible with APR48-3G or APR24-3G rectifiers.
