SSCD355-1500-3800 355kW Diesel Engine Electric Dynamometer Test Bench System

1. SSCD355-1500-3800 355kW Diesel Engine Electric Dynamometer Test Bench System Description

This highly efficient testing solution, specifically designed for medium and large diesel engines (used in heavy trucks, construction machinery, and large generator sets), features a 355kW AC dynamometer equipped with an imported high-power four-quadrant variable-frequency inverter controller. This allows for both forward loading and reverse drag, with tested power transmission back to the grid exceeding 85% efficiency. Core to the XLE-1000 measurement and control system, it supports automated execution of national standard test cycles or customized test procedures, integrates a high-power transient fuel consumption meter, and uses a data acquisition module to capture key parameters such as torque and speed, enabling storage, analysis, and standardized report generation, encompassing the entire testing process.
