# Thread: Units connect to power supplies/a power supply?

1. ## Units connect to power supplies/a power supply?

How should I write in the following case?:

There are three machines (Unit A, Unit B, and Unit C).
Unit A needs a power supply.
Unit B needs a power supply.
Unit C needs a power supply.
Three power supplies are necessary. These machines cannot share a single power supply. These power supplies are all different in supply voltage and type.

In the above case, is the following expression okay?:
1. Unit A, Unit B, and Unit C need a different power supply each.
2. Each of these Units needs a different power supply.

#1 needs to be "Unit A, Unit B, and Unit C each need a different power supply." "Unique" would be better than "different."

#2 is good.

Thank you for your quick response and information.

You could say the each unit needs a dedicated power source. That means that each power source is used by that unit and by nothing else.

Doesn't it mean that there is a single dedicated power source that connectes to all the units, depending on the context?

No. If you say "each unit" needs a "dedicated" power source, Unit A gets power source A, Unit B gets power source B, etc.

You can't read "each unit needs a dedicated power source" and infer that a single power source powers A, B, and C."

Thank you!
