  • Samlex SEC1230A

    I have been reading through the user manual and wanted to see if I was getting it. This is a 30 amp 12v 3-bank charger. It can be set up as either a 2-Stage charger with a load or a 3-stage charger for batteries without load. It is also a DC UPS.

    So I am assuming that:

    1) If three 12v batteries are connected they will each get 10 amps (assuming the batteries are all in the same SOC)
    2) If it is used as a DC UPS, the batteries will discharge as a single bank.
    3) The unit can be configured to charge the bank of 1-3 batteries and be used as DC UPS at the same configuration.

    I would use this as a backup system, so I would not be charging and discharging at the same time.

    Based on what I read your assumptions are almost correct.

    For the first, even if all of the batteries are in the same SOC the amount of current going to each will depend on the circuit resistance. I doubt you will get an even 10 amps going to each battery but you will get 30 amps going to the entire "battery bank".

    I actually like the function of being able to run a DC load and charge a battery and then use that battery as a UPS if the AC to the charger stops.

      How the bank bank is charged and discharged is my main concern. I know that if the batteries are in different stages of charge, that they will all be treated the same, so if one battery was at 50% and another was at 100%, the full battery could get over-charged. However, I am hoping that this is not equivalent to having two or three batteries in parallel. From the sound of it, that is not the case, because they advertise:

      • 3 banks of batteries can be charged
      simultaneously without use of an
      external battery isolator

        With three isolated positive rails, it has the ability to supply 30A of CC. The division of current will depend on the battery's state of charge. I'm pretty sure they don't have 10A limitations on each, since my 15A will do 15A no matter how many batteries are attached. But maybe it would be best to contact them. More docs:

        I believe this is a bit different than say your NOCO type of isolated charger.

          That does help, because that means that while the 12v 30 amp charger that has three banks could work for a Flooded 225AH battery bank it would also work for two or 3 120AH batteries, just not one 120 battery FLA.
