The DSLC™ 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 control is a synchronizer, a load sensor, a load control, a dead bus closing system, and optionally a VAR/PF and process control, all integrated into one powerful, yet convenient package. (product spec 02006) The MSLC control is a microprocessor-based load control designed for threephase electric power generation sites equipped with Woodward DSLC Digital Synchronizer and Load Control units which operate in parallel with the utility. The MSLC is a synchronizer, a utility load sensor, an import/export load level control, a power factor control, and a master process control. (product spec 02021)
The MFR 11 provides voltage protection only, and different packages are available for different applications: • MFR 11/MP package includes protection for over-/under-voltage, over-/underfrequency, and voltage asymmetry faults. • MFR 11/NU package adds a wide range power supply. • MFR 11/VDEW package includes protection for over-/under-voltage, over-/under-frequency, voltage asymmetry faults and protection for phase/vector shift. • MFR 11/G59 package adds protection for df/dt (ROCOF) faults, and five additional relay outputs. • MFR 11/G59N package adds a wide range power supply to the G59 package. • MFR 11/SC package was made for synch-check and zero-voltage monitoring. (product spec 03244)
The MFR 12 provides current protection only, and different packages are available for different applications: • MFR 12/CP package includes protection for time-overcurrent (TOC) and calculated ground faults. • MFR 12/51V package includes protection for time-overcurrent (TOC), calculated ground faults and voltage restraint time overcurrent. • MFR 12/IvIkR package includes protection for ground faults via measurement of the displacement voltage. • MFR 12/50-51GN package includes protection for directional ground faults. (product spec 03249)
