WOPUSAI 12V135 Series 430kVA-750kVA Open Frame Diesel Generator, Standby Power for Data Centers

Product Overview

The WOPUSAI 12V135 series 750kVA diesel generator set adopts STF650 V12 heavy-duty diesel engine, matched with TFW-600 brushless self-excited all-copper alternator. This ultra-heavy-duty open-frame genset is designed for continuous prime power and critical emergency standby power in large-scale industrial projects. Featuring direct injection fuel delivery and high-precision electronic speed regulation, it delivers stable power output and outstanding overload capacity. It is widely adopted for mining operations, large industrial parks, data center backup, municipal water treatment plants and major engineering power supply projects.

Key Specifications

Core Advantages

✅ V12 Turbocharged Intercooled Heavy-Duty Engine: The STF650 V-type 12-cylinder engine with 26.6L large displacement and turbo intercooled structure. It reserves tremendous torque to cope with sudden heavy load impact, capable of long-time continuous full-load operation in harsh working sites.

✅ TFW Brushless Self-Excited All-Copper Alternator: Brushless structure removes carbon brush wearing and periodic replacement work, greatly cutting maintenance workload. Pure copper winding plus AVR automatic voltage regulator maintains steady voltage under frequent load fluctuations.

✅ High-precision Electronic Speed Governing System: The electronic governor responds rapidly to load changes and keeps speed fluctuation within a low range. It protects sophisticated electrical equipment against unstable power supply in important power consumption scenarios.

✅ Oversized Heavy-duty Water Cooling Radiator: Custom large-capacity radiator supports stable operation under ambient temperature up to 40℃, effectively avoiding overheating risks during non-stop full-load running.

✅ IP23 Protection & Class F Insulation: F-class winding insulation promotes high-temperature resistance; IP23 protection prevents solid particles and splashing water, perfectly adapting to mining sites, factories and semi-outdoor complex environments.

🎯 Application Scenarios

Large mining continuous power supply, industrial park main power, data center emergency backup, large sewage treatment plant, large infrastructure construction, remote off-grid power station. Designed for heavy-load and long-duration continuous operation.

⚙️ Optional & Customization

• Silent canopy / Mobile trailer chassis
• ATS automatic transfer switch for automatic startup once mains power fails
• Multi-protection control system (overspeed, high temperature, low oil pressure, overcurrent protection)
• Extended base fuel tank, remote monitoring module
• Custom painting and brand logo printing
