Energy Supply |
| 摘要 |
The invention is an energy supply for a field device that can be operated at a normal voltage, comprising the first energy supply having variable output voltage for the field device, an energy store, which can be charged by means of a charging circuit, which is arranged between the first energy supply and the energy store, wherein a first state, in which the output voltage is above a predetermined value, the charging circuit is switched in such a way that the field device is operated by means of the first energy supply and the energy store is charged, and in a second state, in which the output voltage is below the predetermined value, the charging circuit is switched in such a way that the field device is supplied by means of the first energy supply and the energy store. |

1. An energy supply unit for a field device that can be operated with a nominal voltage, comprising a first energy supply with variable output voltage for the field device, an energy storage unit which can be charged via a charging circuit arranged between the first energy supply unit and the energy storage unit, wherein the charging circuit is switched in a first state, in which the output voltage is above a predetermined value, such that the field device is operated via the first energy supply unit and the energy storage unit is charged, and the charging circuit is switched in a second state, in which the output voltage is below the predetermined value, such that the field device is supplied via the first energy supply unit and the energy storage unit. |
