DSLC Digital Synchronizer and Load Control


    device_dslc.jpg   Not_Preffered_for_NEW_Design

    We've redesigned the DSLC! 


    The DSLC (Digital Synchronizer and Load Control) is a microprocessor-based synchronizer and load control designed for use on three-phase ac generators equipped with Woodward or other compatible speed controls and compatible automatic voltage regulators. The DSLC is a synchronizer, a load sensor, a load control, a dead bus closing system, and an optional VAR/PF and process control, all integrated into one powerful and convenient package.

    Feature overview:

    • Synchronizer and load control in one box
    • Automatic generator loading and unloading for smooth load transfer
    • Isochronous load sharing with other DSLC-equipped sets
    • Process import/export control
    • VAR and Power factor control
    • Dead bus closing
    • Accurate control of non-linear and distorted generator wave forms
    • Digital communications network for information exchange between controls
    • Programmable load switch or reverse power trip output
