Woodward 9907-535
Product Name: Woodward 2301A-LS Low-Voltage Load Sharing Controller
Product Introduction: A derivative model of the 2301A series, focusing on multi-unit load sharing. It simplifies some synchronization functions and specializes in prime mover speed closed-loop and parallel load sharing, suitable for scenarios requiring multi-unit island parallel operation without complex grid-tie logic.
Detailed content
Technical Specifications:
-
Power Supply: 18–40 VDC
-
Speed Sensing: Magnetic pickup input
-
Drive Output: Proportional actuator drive output
-
Operating Temperature: -40°C to +85°C
-
Enclosure Rating: IP20
Functional Features:
-
High-precision speed closed-loop control with isochronous/droop mode switching
-
Multi-unit island parallel load sharing
-
Hardware self-test alarm output
-
External potentiometer for parameter setting
-
No complex synchronization logic, simple and reliable hardware structure
Application Scenarios: Offshore platform island power generation, mining mobile power stations, multi-unit island backup power supplies.
Material Composition: Sheet metal enclosure, single industrial PCB, flame-retardant terminals.
Structural Features: Cabinet-embedded single-board installation; no local display panel.
Working Principle: Acquires speed signals for closed-loop actuator output adjustment; exchanges load signals from each unit via the load sharing bus and dynamically corrects output to achieve load sharing in island mode.
Installation Requirements:
-
Install inside a sealed control cabinet; direct installation on the engine body is prohibited
-
Speed signal lines and load bus must use shielded twisted-pair cable with single-point grounding
-
Keep away from high-voltage interference sources; reserve heat dissipation space
Usage Precautions:
-
No synchronization closing logic; this model is not applicable to grid-tie scenarios
-
The system must be equipped with an independent hardware overspeed protection device
-
Anti-static protection during assembly/disassembly; power polarity must not be reversed
