Isolation

Isolation

Two circuits that are completely electrically separated with respect to DC potentials, and almost always also AC potentials. In power supplies, it is defined as the electrical separation of the input and output via the transformer.

Isolation Voltage

Isolation Voltage

The maximum AC or DC voltage which maybe continuously applied from input to output and/or chassis of a power supply.

Nominal Voltage

Nominal Voltage

A standard value assigned to a circuit for the purpose of conveniently designating its voltage class.

DC Voltage

DC Voltage

Normally, it is used for the battery voltage.

DC Efficiency

DC Efficiency

The ratio of the output power from the UPS to the input power from the batteries in Battery Mode.
