5. During equalization, measure the S.G.
When all cells have an S.G. of approximately 1.265, terminate the charge by
setting the CHARGER switch to DISABLE. As a safety feature, the PROsine
will exit Equalize mode after a specified period (depending on battery type).
If the S.G. is still rising just before the charger exits equalization, restart the
process by requesting an equalization charge.
6. When equalization is finished, check the battery electrolyte level. Top up as
necessary with distilled water only.
Operating Limits for Charger Operation
Output Current: The maximum output current for the PROsine is 100 amps.
You can reduce the total output if you change the Battery Size setting on the
Configure Battery menu (see page 4–12) or the maximum AC Breaker Size
setting on the Configure PROsine— Basic menu (see page 4–7).
Input Voltage:
The charger can operate over the range of 90–135Vac. This wide
range allows the PROsine to deliver a maximum current to your batteries even
when incoming AC voltage is less than ideal. A built-in surge protector protects
the PROsine from surges and spikes on the AC power line.
Power Share
The PROsine shares power with AC loads. It senses pass-through current going to
AC loads and subtracts this current from 80% of the breaker setting. The current
that is left over is available for charging the batteries.
In Charge mode, the PROsine operates from a breaker-protected 120Vac circuit.
Therefore the total power for AC loads and charger operation is limited to 80% of
the breaker rating (80% is the regulatory maximum permitted for continuous
loads). In this limited power environment, the PROsine gives priority to user-
connected AC loads (pass-through current).
Example A 30 amp circuit breaker is allowed to have a 24 amp continuous load.
If you have AC loads of 15 amps, the PROsine will give priority to your loads and
allow the charger to draw up to 9 amps AC.
WARNING: Fire hazard
In this situation it is very important to check the electrolyte level and S.G. in each cell at
least once per hour. The charger should be turned off and the batteries allowed to rest a few
minutes to do this check as the electrolyte will be bubbling if the charger is active. If
further equalization is needed the equalize cycle may be restarted.
