Abstract

The invention concerns a power supply system for a field device connected to a wire-line network with a radio module configured for data communication with an external unit, wherein the radio module is connected to the field device and has a power supply unit. The power supply adapter is provided with a power transmitter for the wireless power transfer to the power supply unit. The power supply unit is configured with a power receiver, while the power receiver and the power transmitter are inductively coupled for the power transfer.

Claims

1. A power supply system, for a field device, comprising:

a power supply system operably connected to a wire-line network with a radio module that is operably configured for data communication with an external unit, wherein said radio module is connected to said field device and has a power supply unit;

said power supply system, further comprising;

a power supply adapter which has a power transmitter for the wireless power transfer to the power supply unit, said power supply adapter operably including a power receiver for a wireless power transfer from an external charging unit,

wherein said power supply unit is operably configured with a power receiver, and said power receiver and said power transmitter are operatively inductively coupled for the power transfer, and

wherein the power transmitter of the power supply adaptor and the power receiver are operative such that when the power transmitter and the power receiver are operatively inductively coupled for the wireless power transfer, a communication connection is also realized, the communication connection providing at least one of an authentication, a thermal checking, and a transmission of charge status.

2. The power supply system, according to claim 1, wherein:

said power supply adapter is operably configured with an energy storage unit for said power supply to said power transmitter.

3. The power supply system, according to claim 2, wherein:
