Description

9905-204 Woodward DSM Synchronizer Module

Product Overview

The 9905-204 Woodward DSM is a dedicated digital synchronizer for generator and turbine parallel operation. It delivers precise voltage matching (±1%) and phase-angle control, ensuring seamless bus coupling in 115/230V-AC systems. Built for extreme environments, this module operates reliably from -35 to 65 °C.

Core Advantages

Rugged 125V dc supply. Small sync window for rapid closure. Non-intrusive speed matching. Direct retrofit for 9900 series and legacy Woodward controls. LED status indicators for voltage, speed, and breaker commands.

Installation Quick Notes

Gap voltage: Set to 2.5 Vdc at speed input (terminals 5-6). Cable: Use shielded twisted pairs; min bend radius 50 mm. Grounding: Follow local ex-proof codes for hazardous areas.

Why Choose 9905-204

Engineered for high-vibration turbine decks. The small sync window reduces mechanical stress. ±1% voltage accuracy ensures stable load sharing. Fully compatible with 3300 series and older Woodward AVRs.

FAQs

Q1: How to set the gap voltage?
A1: Adjust trimmer until 2.5 Vdc is measured at terminals 5-6 with generator at rated speed.

Q2: Retrofit for 3300 series?
A2: Yes, it supports analog/digital outputs for 3300, 2301A, and most AVRs via jumpers.

Q3: What does small sync window do?
A3: Narrows phase-angle tolerance (e.g., ±2°) for reduced mechanical stress and longer turbine life.
