Hi Jim,
I think these chargers are only meant for float charging the battery. They
are not meant to supply a load (GPSDO) current.
It is more for connecting to your motorcycle or tractor battery and keeping
it fully charged over winter storage conditions.
I just picked up a MeanWell 24 volt switcher rated at 24 volts @ 6.5 amps
and has a fine adjustment that will go to >28 volts. Also, it has remote
sense connections. It was $25 including shipping.
Regards,
Tom
