Overview

This document provides detailed technical specifications, performance data, and mechanical dimensions for a series of generator models, specifically the SLG404 series and its variants (SLG404A, SLG404G, SLG404H, SLG404J, SLG404K). It includes power ratings, voltage levels, duty cycles, temperature rise parameters, and mechanical coupling and mounting details.

Power Ratings and Voltage Specifications

The generators are rated for continuous and standby operation with temperature rise limits of 40°C. Power outputs are provided in both kilowatts (kW) and kilovolt-amperes (kVA) across multiple voltage levels, including 380V, 400V, 415V, 416V, 440V, 460V, and 480V.

• Continuous Duty (125k/40): Power outputs range from 600 kW to 1375 kW depending on voltage and model.
• Standby Duty (150k/40): Power outputs range from 544 kW to 1150 kW with corresponding kVA ratings up to approximately 1525 kVA.

Voltage variations affect the power output, with higher voltages generally supporting higher kW and kVA ratings.

Model Variants and Performance

The SLG404 series includes multiple variants (A, G, H, J, K), each with specific power ratings and mechanical dimensions. The document lists detailed kW and kVA values for each model at different voltages and duty cycles.

Mechanical Dimensions and Coupling Details

Detailed mechanical specifications are provided, including:

• External dimensions of the SLG404 models, with lengths ranging approximately from 1548 mm to 1789 mm depending on the variant.
• Disc coupling dimensions and torque specifications: coupling bolts must be tightened to 84 Kgf·m (822 N·m).
• Air inlet and louvre configurations, including standard 60 rippro louvres fitted on marine machines.
• Flange adaptor dimensions and center of gravity (C of G) coordinates for each model variant.
• Shaft extension details, including keyway dimensions and flange SAE numbers (SAE 14, 18, 21, 24, etc.).
