    Exceptionally well proven high-accuracy measurement
    Based on over 40 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 500kA, LKP systems simply have no equal. DynAmp offers both LKP unidirectional/DC measurement systems as well as LKB bi-directional/AC current measurement systems
    • 0.1% accuracy class measurement up to 500kA
    • Non-contact design for installation ease and safety
    • Multi-channel, closed-loop hall-effect technology for superior performance in adverse magnetic, environmental and industrial conditions over the long term.
    • Extremely stable and responsive measurement for superior control performance
    • Split-head design for easy installation, eliminates bus bar cutting
    • Cast Aluminum construction for durability
    • Extremely robust electronics for reliability and long life.
    • Included DynAmp Bus Analysis to ensure highest performance and accuracy in your specific application
    • Available Accuracy Diagnostics continuously monitors system operation to immediately signal customers of operating conditions which could compromise accuracy or performance
    • 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.

    Integrated rectifier measurement and protection
    Knowing different power conversion applications have different performance requirements, DynAmp realized that a new class of measurement was needed. The product had to be dependable and responsive, provide good accuracy with additional functionality tailored specifically for high-power conversion applications. To achieve this, DynAmp worked with leading rectifier manufacturers from initial concept through final design verification.

    DynAmp's LKAT products provide measurement for both rectifier control and protection in a single system. LKAT offers an exceptional and un-matched price/performance balance as compared to any alternative measurement technology.

    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.

    While our LKCO and LKP systems provide the highest degree of accuracy, LKAT systems offer two solid levels of accuracy with a higher degree of functionality and installation flexibility, all at a significantly lower cost.

    Improve rectifier reliability and efficiency
    The RCEM system is used to monitor the “health” of a rectifier by measuring current at each semiconductor device in the rectifier. These measurements are critical for rectifiers to keep up with “capacity creep” expansions and current increases that approach the label current rating for rectifiers. Leading rectifier manufacturers use the RCEM for testing new and existing rectifier installations.
    • Accurately schedule preventative maintenance by monitoring and trending balance of individual currents among parallel rectifying devices.
    • Provide current measurement and alarming capabilities at the rectifying device level enabling \"over-nameplate\" operation, particularly in rectifiers with n-1 capability regarding devices per leg.
    • Characterize rectifiers during acceptance testing or commissioning of new power conversion equipment.
    • Portable, rugged, dependable and easy to install and use.

    Special note regarding semiconductors :

    DynAmp is now pleased to offers discrete semiconductor profiling both on-site and in our factory. Benefits include reduced current imbalance between devices resulting in longer, more consistent semiconductor life and reduced maintenance and repair costs.
    • During rectifier rebuilding, optimize semiconductor matching within each leg.
    • Ensure replacement semiconductors match those already operating on the same leg
