(1) The upper limits of the range adjustments have a tolerance of ±5%.
(2) The Equalize voltage can not be set higher than the Overvoltage protection level.
(3)
For the following models VOVP is 120% ±7% of VSET - Latch-style tracking overvoltage protection: TBC 12-50M,
TBC 12-100M, TBC 24-25M, TBC 24-50M, TBC 24-100M, TBC 48-12M, TBC 48-25M, and TBC 60-25M. Cycle power
to reset. Setting the TBC to less than 13% below the battery voltage may trigger OVP protection that requires power
cycle to reset.
