5503-173
WOODWARD 5503‑173 is a microprocessor‑based digital synchronizer & load‑sharing speed controller manufactured by Woodward, USA, belonging to the MicroNet series control modules. It is specially developed for three‑phase AC generators driven by diesel, gas engines and steam/gas turbines, integrating automatic synchronization, speed regulation, load distribution and parallel operation control functions, widely used in power generation, petrochemical, marine power and compressor control systems.
Description
Product Details
This module adopts high‑precision microprocessor control, automatically completes frequency, phase and voltage matching for generator synchronization, and outputs analog/discrete bias signals to realize soft grid‑connection and load transfer. It provides stable speed‑load closed‑loop control for single/multi‑unit parallel operation, with high‑precision load sharing.Equipped with independent RS‑232 and RS‑422 serial communication ports, it supports low‑current PWM control output, and can be connected with DCS, PLC and SCADA systems for parameter configuration and data monitoring. Industrial‑grade hardware design has excellent anti‑electromagnetic interference, anti‑vibration and wide‑temperature adaptability; plug‑in modular structure is compatible with MicroNet control chassis, with built‑in self‑diagnosis, fault alarm and protection functions, supporting long‑term continuous stable operation.
