maximum dc voltage output Magnum 3012 with remote

[pianotuna]

Hi,

I was toying with my charge voltages. I wanted to try 15.4. When I set 15.4 on the remote it did not get above 14.7 volts. The bank was fairly full so it was only doing between 8 and 10 amps of charging.

Does anyone know the maximum dc output voltage?

First reply is to use the setup menu to adjust the float voltage. I wrote back and told them I had already done that.

I've just emailed Magnum and will report back what they say.

I think the idea is to try something different. Otherwise best to contact Magnum.

Just tried this again.

At 15.4 set on remote I got a maximum voltage of 14.8 at the battery terminals. Amps were 8.0. It is 11.7 c (53.1 f). I ran the test for 10 minutes. When I "backed off" to a float of 13.2, charging went to 13.5 volts @ 0 amps. After another ten minutes that went to 13.5 @ 8 amps.

time2roll,

They were only charging at 9 amps.

I'm using the "custom" setting on the remote.

Try 14.9 next time you run them down a bit. Is there a second limitation by battery type etc? Maybe reduce the amp rating to 50% of max.

If your battery is at or near charge capacity of 14v, your voltage will be regulated down from 15.4volts. If your battery was sitting at a lower capacity such as 10volts when you would see higher charging output voltage. This can usually be confirmed by using a volt meter while briefly disconnecting the positive lead from the charging source simulating a fully discharged battery. This would command 15.4v max charge. Running the charger like this for an extended time could cause damage.

Hi,

The banks were at 19.5 C, so I think it is not temperature related.

It may have been limiting due to temperature. I know those will do well over that voltage for equalization.
