Education
Equipment on a 24 Vdc bus may have an upper supply voltage limit of 30 Vdc; on a 125 Vdc bus, the upper limit is usually 150 Vdc. A dc system design that includes equalization must keep these voltage limits in mind. The maximum equalize voltage for the battery must be less than the lowest upper-voltage limit for any connected equipment.
