Overview

The Woodward 9905-367 DSLC is part of Woodward’s DSLC series, engineered to simplify generator set automation. It ensures frequency, phase, and voltage matching for safe generator synchronization, while also managing load sharing and VAR/power factor control.

Moreover, it supports dead bus closing and process import/export control, making it ideal for multi-generator installations in industrial and utility environments.

Technical Data

Key Features

• Synchronizer + Load Control in one unit → reduces hardware complexity

• Automatic generator loading/unloading → ensures smooth (bumpless) load transfer

• Isochronous load sharing → balances load across multiple DSLC-equipped sets

• Dead bus closing → allows safe connection to a de-energized bus

• VAR or Power Factor control → maintains reactive power balance

• Process import/export control → manages power flow between utility and generator systems

• Accurate synchronizing → frequency, phase, and voltage matching

FAQ

Q1: What makes the 9905-367 unique compared to older synchronizers?
A1: It integrates synchronizer and load control functions into one unit, reducing complexity and improving reliability.

Q2: Can it handle multiple generator sets?
A2: Yes. It supports isochronous load sharing among DSLC-equipped sets.

Q3: Does it support reactive power management?
A3: Yes. It can operate in either VAR control or power factor control mode.

Q4: What is “dead bus closing”?
A4: It allows safe connection of a generator to a bus that is not energized, preventing unsafe conditions.

Q5: Is it suitable for utility tie applications?
A5: Yes. It includes process import/export control for managing utility interconnections.
