Product Description

This control is a Woodward DSLC Digital Synchronizer and Load Control unit, part number 9905-368. This part is a microprocessor-based control for paralleling, synchronizing, loading, and unloading of three-phase generator sets. It is designed for use with a Woodward speed control and an automatic voltage regulator (or other compatible device). Part 9905-368 is intended for applications which do not require integrated power factor or process control. it is a reduced upgrade level DSLC part number and therefore does not have power factor control or process control functions.

This control is rated for operating temps from –40 to +70 °C (-40 to 158 F) and storage temps from –55 to +105 °C (-67 to 221 F). Additional environmental specifications for the 9905-368 are:

  • Humidity …... 95% at 38 °C
  • Mechanical shock …... US MIL-STD 810C, Method 516.2, Procedures I, II, V
  • Electromagnetic susceptibility …... ANSI/IEEE C37.90.2; ANSI C37.90.1-1989
  • Vibration …... US MIL-STD 167, Type I

Either phase matching or slip frequency synchronizing are available with the 9905-368. For both methods, actual slip frequency and breaker delay values are used to anticipate a minimum phase difference between generator and bus at actual breaker closure. There is an automatic dead-bus closure function on this control, where only one DSLC control is granted dead-bus closing permission through locking techniques over the communications network.

Additional synchronizer features that may be enabled or disabled during setup include time-delayed automatic multi-shot reclosing, voltage matching, auto-resynchronizing, and synchronizer timeout alarm

Reviews For 9905-368

Internal Review

Load control begins at breaker closure when the load control function takes control of the 9905-368 speed bias output directly from the synchronizer. The matching of synchronizer slip frequency to initial load can result in a bumpless transfer to load control. - AX Control
