Description
The AQM20 supervised power supply with battery
charger is two high powered, fully isolated, independent
power supplies enclosed in one small self contained
aluminum package. Each power supply, outputs 1 and
2, are a nominal 12vdc at 10 Amps with 12v lead acid
battery charger. These outputs can be used as
separate isolated 12vdc power supplies, or they can be
connected in parallel or series to provide 12vdc, 24vdc
or both 12vdc and 24vdc at the same time. When
outputs 1 & 2 are connected in parallel, the output is
13.75vdc at 20 Amps. When outputs 1 & 2 are
connected in series, the output is 27.5vdc at 10 Amps.
Because each output is independently regulated, you
may draw additional current from the 12V output 1,
while using the 24vdc output at the same time. The
12v current used has to be subtracted from the 10
