Main Technical Specifications

Alternator Configuration

The alternator configuration is designed for 50Hz, 400/230V output with Class H insulation, IP23 protection, three-phase connection and low waveform distortion. Final alternator brand and model are subject to the confirmed technical configuration and formal quotation.

Control System

The SWT single-unit control system provides a user-friendly operating interface and essential genset monitoring functions. It supports LCD display, key operation, multilingual display, generator parameter detection, engine parameter detection, local and remote start, event logs and protection functions.

• Automatic/manual start and stop operation.
• Voltage, current and operating status monitoring.
• Alarm lamps and event logging for maintenance reference.
• Configurable parameters through panel operation or PC software.
• Multiple communication interface options available according to project needs.

ATS Optional

An ATS panel can be supplied as an optional configuration for mains-to-generator or mains-to-mains automatic transfer applications. The ATS controller integrates measurement, display and control functions, and supports automatic switching between two power sources. The reference switching time is up to 80ms under the stated ATS configuration.

SWT Paralleling System Optional

For projects requiring multiple units or generator-to-grid operation, SWT can provide a paralleling system for set-to-set or set-to-grid applications. The system can synchronize up to 32 units automatically, support automatic start and parallel operation, and manage the number of running units according to load demand.

• Suitable for genset-to-genset, genset-to-grid and paralleling-with-ATS applications.
• Can help avoid inefficient operation of high-power units under small load.
• Flexible expansion by adding additional gensets according to future capacity needs.
• PLC system and touch screen options can be customized according to project requirements.

Applications
