High Accuracy Uni-Directional (DC) Current Measurement

Based on over 60 years of know-how and expertise, DynAmp LKP systems are the most proven high-accuracy DC current measurement systems available for electro-industrial applications. With 0.1% accuracy performance at current ranges up to 80kA, LKP systems simply have no equal. DynAmp offers both LKP unidirectional/DC measurement systems as well as LKB bi-directional/AC current measurement systems.


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 imbalance on the control of the rectifier.
