Equalize battery charge: In association with a Lineage
®
2000 MCS controller, the J85502C-1 rectifier allows the
batteries to be charged at a voltage that is higher than float
voltage to equalize the individual voltages of the cells in the
string.

Features
Dynamic Response
For any step load change of 10 to 90 percent, or 90 to 10 percent,
or a step change of 10 percent of the input voltage, the sense
point voltage remains within 5 percent of its setting, and returns
and remains in the 1/2 percent band within 300 milliseconds.
For batteryless operation, for any step load change of 50 to 90
percent, or 90 to 50 percent, or a step change of 10 percent of the
input voltage, the sense point voltage remains within 10 percent
of its setting, and returns and remains in the 2 percent band
within 500 milliseconds.
Electromagnetic Compatibility (EMC)
The J85502C-1, 125-ampere rectifier complies with FCC
Docket 20780, Part 15, Subpart J as required for Class A
applications. In addition, the rectifier meets all specified
operating specifications when subjected to electric fields up to
10 volts per meter over a frequency range of 20 to 1000 MHz.
Circuit Modules
The rectifier’s signal processing and control circuitry are located
on replaceable circuit modules or packs. Circuit modules are
plug-in boards that can be ordered. Table 8-A lists recommended
spare parts for the rectifier. All of the circuit modules are
accessible by opening the rectifier door. Figure 5-3 shows the
location of the circuit modules and other features of the rectifier.
Figures 6-2, 6-3, and 7-2 show the CM1, CM2, and CM3 board
layouts, respectively. A description of each module follows.

The CM1 circuit module (ED-83158-30, Group 3) contains
circuitry common to several rectifiers in the Lineage

rectifier family. The factory provides the options required
for each application by removing certain wire straps and
resistors from the CM1 board. The factory modification of
CM1 is complete when the board is installed in the rectifier.
However, ordered spare or replacement CM1 boards have
not been modified. The customer must make this
