Abstract
Official abstract text for this publication.
A power and control unit for low and medium voltage applications, operatively couplable to one or more circuit elements of a low or medium voltage apparatus, is provided. The unit includes an internal self-diagnostic circuit element operatively coupled to a signal-generating circuit element, a binary input operatively coupled to the internal self-diagnostic circuit element, and a low-impedance variable load connectable in parallel to the binary input. The binary input includes a control circuit element operatively connected to the low-impedance variable load and also operatively connected, through a signal-detecting circuit element, to the internal self-diagnostic circuit element and to the one or more circuit elements of the low or medium voltage apparatus.
