DEFINITION

Classification: 307/33

(under subclass 31) Subject matter relating to means for keeping the current or power constant in magnitude.

(1) Note. This subclass relates, for example, to systems wherein a useful load is replaced by a dummy load, of equal size, when the useful load is no longer desired, so that the

magnitude of power drawn from the line is constant.
