  • Available totalizing equipment sums multiple LKP system measurements while maintaining high accuracy

Special Note Regarding Rectifier Control : By measuring the actual DC output of the rectifier, the control loop is dramatically shortened for superior responsiveness as compared to other, more ‘remote’ measurement points such as ACCT measurement on the primary side or ‘measurement’ windings within the rectifier transformer. Using the actual DC output of the rectifier as the control input eliminates the effects of changes in rectifier / transformer efficiency, dynamics between multiple transformer secondaries and phase un-balance on the control of the rectifier.
