Abstract (en)

The present invention relates to an operation voltage controller for a signal powered field device having a display, comprising a power supply for transforming the signal into a high voltage output and a low voltage output, a basic device functions means being supplied by the low voltage output such that an operation voltage is applied at the basic device functions means, and a back lighting means for back lighting a display of the signal powered field device. The present invention relates also to a method for controlling an operation voltage controller of a signal powered field device having a display, wherein the operation voltage controller comprises at least a basic device functions means, the method comprising the following steps: transforming the signal into a high voltage output and a low voltage output, supplying the basic device functions means with the low voltage output such that an operation voltage is applied at the basic device functions means, and back lighting a display of the signal powered field device.
