Why are there two different output ratings (two pairs of each voltage and amperage) on my AC adapters? What does it mean?

    What does it say??

    Outputs? Because many require two different voltages to run different circuits. Logic usually requires +5 volts. Some require isolated higher voltage to run toner corona generator, you don't want that HV even sharing same ground as the logic circuits.

    Source(s): Repaired switching/.analog power supplies professionally 8 years. All supplies have input requirement; many need to be switched between 240-to-120 VAC. Some are auto sense. Our PSs had multiple outputs; often +/- 5 volts at hi amps for logic; +/-12 volts; -48 volts for tip/ring; plus 88-108 volts at 20 CPS for ring signal.

    A MULTI OUTPUT VOLTAGE SPECIAL MADE ADAPTER TO SUPPORT SPECIAL MADE DEVICE OR OUT OF DAY DEVICE. YOU MAY USE JUST SINGLE OUTPUT AS WISH.

    It is a dual output adapter for something like a printer, which uses two power supplies. One, low current, for logic and one, high current, for hot wires.

    Look at the illustration of the connector, to the right of the voltage / current ratings. This AC adapter provides two different voltages at the same connector: 16 Volts between one pin and ground, and 32 Volts between the other pin and ground.

    it means different input will give you a different voltage and amperage as output

    From the photo it either has a switchable output or two outputs.

    Your AC adapter supplies both voltages - kind of like a duel adapter.

    Call HP support and ask there. Your photo is not readable.
