For industrial plant managers, commercial facilities, and backup infrastructure engineers, securing a resilient power backup matrix requires a heavy-duty system capable of immediate load acceptance. The Cummins C80D5 Diesel Generator Set delivers an integrated, fully engineered power generation system designed to maintain strict voltage stability across standby, prime, and continuous operations.
Built under centralized global manufacturing and testing standards, the C80D5 combines high-displacement engine performance with sophisticated digital control systems. Below is the technical breakdown of its mechanical specifications, electrical tolerances, and operational parameters for commercial procurement.
Core Engineering and Component Architecture
The C80D5 integrates a factory-matched powertrain where the engine, alternator, and control subsystem are built to run as a single, highly calibrated unit, ensuring immediate system response:
- Industrial Engine: Powered by the proven Cummins 6BTA5.9-G1 engine, a robust mechanical platform featuring advanced turbocharging and charge-air cooling for efficient combustion.
- Heavy-Duty Alternator: Equipped with a Stamford UCI224F alternator, providing superior motor-starting capabilities and excellent fault-clearing performance.
- Digital Control System: Managed via the PowerCommand PC1.1 control panel, providing integrated voltage regulation, digital metering, automated engine protection, and fault-diagnostic monitoring.
Technical Specifications and Power Ratings
Engineered in compliance with ISO8528-2005 and GB/T2820-2009 standards for reciprocating internal combustion engine-driven AC generator sets, the C80D5 maintains precise ratings definitions across varying duty cycles:
1. Output Ratings (50 Hz Configuration)
- Emergency Standby Power (ESP): 80 kVA / 64 kW (Optimized for varying electrical loads during utility power interruptions in compliance with ISO 3046 and DIN 6271).
- Prime Power (PRP): 73 kVA / 58 kW (Applicable for unlimited operational hours under varying loads, featuring a 10% overload capability for temporary peak demands).
2. Electrical and Operational Parameters
- Voltage Regulation (No Load to Full Load): Maintained within a strict ±1% tolerance to protect sensitive downstream electronic equipment.
- Steady-State Voltage Variation: Complies with ±1% limits under continuous operation.
- Frequency Regulation / Variation: Drops just 1.40% from zero to full load, keeping steady-state frequency variation under ±0.25%.
- Electromagnetic Compatibility (EMC): Fully certified under BS EN61000-6-4 and BS EN61000-6-2 heavy industrial standards.
3. Fluid Capacities and Fuel Economy
- Fuel Consumption Rate: Highly optimized fuel injection system drawing 16.3 Liters per hour (L/hr) at 100% full load operation.
- Cooling Infrastructure: Features a total coolant capacity of 34 Liters across the engine block and standard radiator tank assembly.
- Lubrication Architecture: Equipped with a 16-Liter integrated bottom oil tank for extended maintenance intervals.
Physical Footprint and Installation Dimensions
The structural layout of the open-set configuration is designed for compact footprint allocation in generator rooms or enclosed canopies:
- Total Length (A): 2268 mm
- Total Width (B): 1050 mm
- Total Height (C): 1553 mm
- Dry Machine Weight: 1392 kg (Sturdy, rigid base frame with integrated vibration isolation pads).
Global Compliance and After-Sales Support
Every C80D5 generator set is manufactured within facilities certified to ISO9001 and ISO9002 standards. Because all major components are engineered directly by Cummins, buyers benefit from a centralized product warranty covering the engine, alternator, and control array simultaneously. This factory-backed assurance eliminates third-party component disputes and streamlines regular maintenance routines.
