Product Description
Woodward 8923-1262 DSLC-2 Digital Synchronizer
Product Overview
- The Woodward 8923-1262 is a DSLC-2 (Digital Synchronizer and Load Control), designed for precise synchronization and load sharing of generator sets in industrial power generation applications, including standalone systems, parallel operation with other generators, or grid paralleling. This microprocessor-based control unit is part of Woodward’s DSLC-2 series, offering advanced synchronization, load management, and power control for diesel, gas, or dual-fuel generator sets. The DSLC-2 provides automated breaker closure, voltage and frequency matching, load sharing, and power factor control, making it ideal for complex multi-unit power systems. The 8923-1262 is a specific variant of the DSLC-2, potentially featuring updated firmware, specific hardware configurations, or additional certifications compared to other DSLC-2 models. It is designed to work seamlessly with Woodward’s MSLC-2 (Master Synchronizer and Load Control) for system-wide control and integrates with other Woodward governor systems. The 8923-1262 features robust communication protocols and a rugged design for reliable operation in harsh environments. It is distinct from Woodward’s EasyGen series (e.g., 8440-2179 EasyGen-3500XT, 8440-2050 EasyGen-3200-5), EGCP-3 series (e.g., 8444-1082), SPM-D2 series (e.g., 8446-1048), MicroNet Plus (e.g., 8800-1001), TG-13 (e.g., 8516-050), 2301D/E series (e.g., 8273-1011), 505D series (e.g., 8200-1300), Peak150 series (e.g., 8200-176), ProAct series (e.g., 8237-2595), 723PLUS series (e.g., 8270-1013), EPG systems (e.g., 8290-195), electronic governors (e.g., 8406-121), and actuators (e.g., 8408-921), focusing specifically on digital synchronization and load control.
