WOODWARD 9903-543 Automatic generator load controller

WOODWARD 9903-543 is an automatic generator load controller launched by Woodward. The following is a detailed introduction:

Product Overview

WOODWARD 9903-543 is mainly used to optimize the load distribution between multiple generator sets, which can achieve smooth load conversion, reduce equipment pressure, ensure system stability when power changes, and effectively manage the load distribution of 1 to 15 generators, and control them through auxiliary circuit breaker

Technical parameters

Dimensions: 8.5 inches wide × 7.5 inches high × 2 inches deep.

Weight: 2 pounds 4 ounces.

Power supply: 12 to 24V DC.

Operating temperature range: -20°C to + 70°C (-4°F to + 158°F).

Control signal: Supports analog and digital control signals.

Communication protocol: Compatible with a variety of communication protocols for easy integration with existing systems.

Load control: Enables smooth loading and unloading of the generator to prevent power surges.

Slope regulation: Features an adjustable electronic ramp for precise load control.

Basic load capacity: Maintains a specific load level even when not participating in load sharing

Introduction to the Woodward Speed Controller 2301E Series
The control functions based on the Woodward 2301E microprocessor are similar to those of the 2301A load sharing and speed control as well as the 2301D load sharing and speed control.
This control device is installed in a metal plate chassis and is used in both ordinary and hazardous locations, and consists of a single printed circuit board.
The 2301E is configured using a computer with Control Assistant software or the Woodward ToolKit service tool.
The controller is powered by a 24 Vdc power supply.
2301E includes:
1 load sensor circuit
1 actuator driver, 4-20 mA, 0-20 mA, 0-200 mA or PWM
1 MPU speed sensor
1 configurable analog output
2 configurable analog inputs
8 discrete (switch) inputs
4 discrete (relay driver) outputs
