WOODWARD 8440-1713 SPM-D1115B/LSXR Generator Controller
WOODWARD 8440-1713 (SPM-D1115B/LSXR) is a digital synchronizer and load sharing controller for generator paralleling systems. It monitors voltage, frequency and phase angle, executing automatic synchronization and load distribution between multiple gensets connected to the grid or island bus.
Equipped with LCD display and keypad for local configuration and status viewing, it supports Modbus communication for remote monitoring. It provides protective functions such as voltage and frequency checking. It is end-of-life, supplied as surplus or refurbished spare parts for legacy power generation system maintenance.

FAQ
| No. | Question & Answer |
|---|---|
| 1 | Q:What is WOODWARD 8440-1713? A:It is Woodward SPM-D1115B/LSXR synchronizer and load sharing controller. It automatically synchronizes generators with the bus and balances active/reactive load among multiple paralleling gensets for stable power output. |
| 2 | Q:What is the difference between synchronizer and load sharing? A:Synchronizer matches voltage, frequency and phase to safely close the breaker. Load sharing distributes total load evenly among online generators after paralleling to prevent overload on single unit. |
| 3 | Q:Is WOODWARD 8440-1713 still in production? A:This SPM-D11 controller has been discontinued by Woodward. Available stock is new surplus or refurbished spare parts for replacement of existing generator paralleling control cabinets. |
