Woodward 4930‑2359 Power Supply Module
Overview
The Woodward 4930‑2359 is a power supply module for Woodward industrial control systems, specially designed for turbine and generator set control systems to deliver stable and continuous power supply for the entire control unit. The 4930‑2359 converts input voltage into multiple DC outputs required by internal system boards, performing system voltage regulation and surge suppression functions to ensure stable operation of the whole control hardware under fluctuating working conditions. Frequently used as an internal power‑supply unit for rack‑mounted control systems, it acts as a critical spare part in oil‑gas power generation and steam turbine control applications. A fault on the 4930‑2359 will directly result in shutdown of the complete control system.
Technical Specifications
Input Voltage: 85‑264VAC wide‑range AC inputOutput Type: Multiple isolated DC outputsOperating Temperature: ‑20℃ ~ +70℃Mounting Method: Rack slot‑in mountingIngress Protection: Industrial board‑level protection, suitable for internal cabinet environmentAnti‑interference: Built‑in surge, over‑current and over‑voltage protection circuitsDimensions: Standard industrial module form factor, compatible with corresponding system rackCooling: Natural air cooling, no extra fan requiredCompatible Signals: Matches internal bus power supply circuit of Woodward control systems
Core Functions & Advantages
It provides multiple isolated outputs with electrical isolation among different circuits to reduce mutual signal interference.Equipped with comprehensive protection logic, it activates automatic protection upon over‑voltage, over‑current and short‑circuit conditions to lower the risk of downstream board burnout.The 4930‑2359 features high tolerance to grid voltage fluctuations and maintains stable outputs even under unstable on‑site power grid conditions.Direct slot‑in structure enables fast on‑site assembly and disassembly, minimizing equipment downtime for maintenance.Its power output matches the power consumption of the whole control system, avoiding insufficient power margin or overload issues.
Product Features
Adopts integrated board‑level design with component layout complying with industrial control standards.All output circuits have independent protection; a single‑channel load fault will not cause total output power failure.The 4930‑2359 is equipped with voltage monitoring points for the system to read power supply status, facilitating maintenance personnel to troubleshoot power‑related faults.Resists on‑site vibration and temperature variation, adapting to harsh operating conditions inside industrial control cabinets.Fully matched interface definition for target racks, supporting direct replacement without additional wiring modification.
Application Fields
Internal power supply for gas turbine control system cabinetsComplete control cabinets for diesel and gas generator‑setsControl units for oil & gas compressor unitsSupporting for steam turbine speed‑governing control systemsFactory captive power stations and distributed energy equipmentIndustrial control cabinets for offshore platforms and field stations
Product Comparison
Compared with other power supply modules in the same series, the Woodward 4930‑2359 features an integrated rack slot‑in solution with multiple isolated outputs, designed for large turbine unit control systems.Some alternative models are external standalone cabinet‑type power supplies suitable for external mounting and do not support rack slot installation; others come with fewer output circuits and are only compatible with small generator‑set controllers. The 4930‑2359 delivers high integration, direct rack insertion and multi‑channel isolated outputs, making it ideal for complex large‑scale control systems with multiple boards. Its limitation is that it must be used with a dedicated rack and cannot operate as a standalone external power unit.

FAQ
Q1: Can the Woodward 4930‑2359 be hot‑swapped for replacement after failure?A: Hot‑swapping is not recommended. Power off the entire control system before removing or installing the 4930‑2359. Hot‑swap operations may damage backplane circuits and further expand the fault scope.
Q2: What are the common causes of unstable output voltage for the 4930‑2359?A: First check fluctuations of the front‑end input voltage, then inspect oxidation on rack backplane contacts. Internal component aging of the module is another possible cause, which shall be confirmed via hardware inspection.
Q3: Can power supply modules from other brands serve as a direct replacement for the 4930‑2359?A: No. It features specific internal output timing, isolation specifications and pin definitions. Generic third‑party switching power supplies cannot be used for direct replacement; only matching model is acceptable.
Q4: What is the typical lead‑time when purchasing the 4930‑2359?A: Items in stock can be shipped promptly. If out of stock, delivery will follow supplier scheduling. Final lead‑time is subject to real‑time quotation feedback.
Q5: What are the requirements for storage environment of the 4930‑2359?A: Store indoors in dry and well‑ventilated conditions. Keep away from humidity, dust and corrosive gas. Outdoor storage is prohibited.
