QSK50 Cummins Diesel Generator

Cummins QSK50 Diesel Generator is one of the most powerful and best diesel generators in the market. The generator operates using a powerful Cummins QSK50 diesel engine, which is specifically designed for industrial and commercial applications. Cummins QSK50 diesel engine has a power between 1100 to 1500 kW, 60 Hz. It can provide electricity for buildings and industries. The diesel generator has an intelligent control system that can accurately adjust the required fuel. This feature, combined with an air cooling system and fuel injection system to improve fuel efficiency and reduce fuel consumption, makes the generator an excellent choice from economic and organizational aspect.

Quantity

In short, the Cummins QSK50 diesel generator is a unique generator with high power and efficiency, smart systems and advanced safety. It has suitable design for industrial and commercial environments.

PowerCommand control 

is an integrated generator set control system providing governing, voltage regulation, engine protection and operator interface functions. Major features include: 

  • Integral AmpSentry™ Protective Relay providing a full range of alternator protection functions that are matched to the alternator provided. 
  • Battery monitoring and testing features and smart starting control system.
  • Three phase sensing, full wave rectified voltage regulation system, with a PWM output for stable operation with all load types. 
  • Control suitable for operation in ambient temperatures from -40 °C to +70 °C (-40 °F to +158 °F) and altitudes to 5000 meters (13,000 feet). 
  • Prototype tested; UL, CSA, and CE compliant. 
  • InPower™ PC-based service tool available for detailed diagnostics. 
  • Optional Echelon® LONWORKS® network interface.

Cummins® commercial generator sets are fully integrated power generation systems providing optimum performance, reliability and versatility for stationary Standby and Prime Power applications.

Cummins heavy-duty engine - Rugged 4-cycle industrial diesel delivers reliable power, low emissions and fast response to load changes. 

Alternator - Several alternator sizes offer selectable motor starting capability with low reactance 2/3 pitch windings, low waveform distortion with non-linear loads and fault clearing short-circuit capability.

Permanent Magnet Generator (PMG) - Offers enhanced motor starting and fault clearing short circuit capability. 

Control system - The PowerCommand® digital control is standard equipment and provides total genset system integration including automatic remote starting/stopping, precise frequency and voltage regulation, alarm and status message display, AmpSentryTM protective relay, output metering and auto-shutdown at fault detection and NFPA 110 Level 1 compliance. 

Cooling system - Standard and enhanced integral set-mounted radiator systems, designed and tested for rated ambient temperatures, simplifies facility design requirements for rejected heat. 

NFPA - The genset accepts full rated load in a single step in accordance with NFPA 110 for Level 1 systems. 

Warranty and service - Backed by a comprehensive warranty and worldwide distributor network.
