ABSTRACT:
A remotely controllable, full scale, AC or DC power attenuator, for attenuating power to a load as a function of an input control signal which represents a selected percentage of power to be applied to the load. Bidirectional series switch means are responsive to the input control signal for connecting and disconnecting power to the load.
