9905-760 Woodward Digital Synchronizer Module

Product Overview

The Woodward 9905-760 is a Digital Synchronizer and Load Control Module for multi‑generator power systems. It measures frequency and phase angle, provides precise synchronisation signals, and regulates load sharing to maintain stable voltage and frequency. Ideal for parallel generator operation in power generation and marine applications.

Core Advantages

Precise Digital Synchronisation

Microprocessor‑based measurement of frequency and phase angle. Synchronises multiple generators before grid connection. Automatic or manual operation modes.

Intelligent Load Control

Monitors load demand and adjusts generator output. Prevents overloading and overheating. Enables efficient load sharing across parallel units.

Communication Ready

Supports LinkNet termination resistor module with screw clamp terminals. Interfaces with other control systems for integrated power management.

Specifications

Installation Tips

Cabinet Grounding

Use a six‑sided metal enclosure. Solid metal doors are preferred. If a window is required, ensure >20 dB RF attenuation from 10 kHz to 1 GHz.

Cable Entry

Limit cable entry holes to 152 mm (6 inches) maximum aperture. This is critical when RF transmitters (handheld radios) are near cable access points.

Bonding

Bond the cabinet frame and all mounting areas together to ensure proper grounding and EMI protection.

LinkNet Wiring

Use the termination resistor module with screw clamp terminals for reliable communication network termination.

Why Choose 9905-760?

Delivers precise generator synchronisation and load sharing in a single module. Microprocessor‑based control ensures accurate frequency matching. Automatic or manual modes provide operational flexibility. Robust cabinet grounding guidelines ensure reliable performance in EMI‑prone environments. Trusted by power plants and marine vessels worldwide.

FAQs

Q1: What is the difference between automatic and manual modes?
A1: Automatic mode handles synchronisation and load sharing without operator intervention. Manual mode allows operator‑controlled adjustment via external signals.

Q2: Why is the 152 mm cable entry restriction important?
A2: Limits RF interference from handheld radios or transmitters near cable entry points. Prevents EMI coupling into control wiring.

Q3: Can this module synchronise more than two generators?
A3: Yes. The 9905-760 supports parallel operation of multiple generators in a power system.
