Designed to convert line voltage ac input into lower voltage ac or dc output, convert to only one output voltage at a time, contained in a separate physical enclosure from the end-use product, and does not have batteries or battery packs that physically attach directly (including those that are removable) to the power supply unit.
List Options |
Option Definition | Unit of Measure | |
|---|---|---|---|
| AC to AC | An external ac-ac power supply is an EPS designed to convert line voltage ac input into lower voltage ac output. | None | |
| AC to DC | An external ac-dc power supply is an EPS designed to convert line voltage ac input into lower voltage dc output. | None | |
| Low voltage | A low voltage model is an external power supply with a nameplate output voltage likely less than 6 volts and a nameplate output current greater than or equal to 550 milliamps. | None | |
| No load | The condition in which the input of a power supply is connected to an ac source consistent with the power supplyÕs nameplate ac voltage, but the output is not connected to a product or any other load. | None | |
| None | None | None | |
| Not applicable | Not applicable | None | |
