ABSTRACT:
A solid state control system for controlling a high voltage primary power pplied to a plurality of power supplies by means of a TTL voltage level. Circuit means are provided to sense the power supply whose DC voltage goes to zero volts due to circuit anomalies, or other reasons. Upon sensing the anomaly the indicator means indicate via a storage device which power supply has failed, before interrupting the primary power.
