SmartUPS SUA3000UXI battery charge cutoff voltage

[Anonymous user]

Hi,

I'm using two SUA3000UXI systems with an external 48V battery bank, and wanted to know at what

voltage level the built-in charger is set to cut-off, and whether this voltage level can be tuned using

Powerchute or console access.

Thanks,

Sanjay

These UPSs will become programmed with a float voltage setting (somewhere around 55.XX vDC to keep batteries at the proper float voltage for a 48V system) and it is not something the user could adjust or should ever need to adjust while using the UPS in a supported manner (so we don't need to give users the ability to change it).

Angela, thanks for the quick response.

>> (somewhere around 55.XX vDC..)

Is an even more precise float voltage indication available?

Thanks,

Sanjay

I don't honestly know the actual value unfortunately but either way, I don't think I'd be allowed to post it here.

What's the boost and absorption voltage on this model?

[Anonymous user]

Not the auto voltage regulation on the (AC) input side, but the charging protocol for the battery.

i.e the boost, absorption and float voltage levels for the three-stage battery charging, that is

typical for lead acid batteries

Are you talking about Automatic Voltage Regulation or something else?

We don't have these units in NAM so I don't have much data on them unfortunately. For more specific data, your local customer care center might be able to research it further.

All I know at this point specifically with my resources here in NAM is that the system is designed for a 48V Lead Acid battery system.
