Controller Battery Charge Current Limit Feature
Functionality: After a failure of the input source (commercial AC) or when some battery cells are permanently damaged, the current
to the batteries can be quite extensive. To avoid overheating or further damages to the battery, the controller can be programmed to
limit the battery current to a preset level by limiting the charging voltage of the rectifiers. Should the battery current still exceed a
higher preset value, an alarm is issued.
The controller limits the current going to the batteries based on the “Battery Current Limit” set point which is a percentage of the
battery capacity in C10. For example, 0.1C10 would mean 10% of the battery capacity.
Refer to the mini control unit Instructions (UM1M831ANA) to program this feature. Battery charge current is limited to the value set in
the controller, as long as battery voltage is above 47 VDC.
