Diesel generator set K50 series

Reliable and durable

Cummins® ‘K50 series’ diesel engine with strong regrindable crankshaft, high strength connecting rod, low pressure fuel lines, STC (Step Timing Controls) injectors and high volume coolant system make ‘K50 series’ generating sets, more reliable and durable. Engines have clocked millions of hours, operating on some of the world’s most demanding conditions. Current engines are upgraded with new technologies for better performance and economy. The ultimate proof of superior performance and reliability is the fact that Cummins® entities worldwide source these engines from Cummins India for their markets.

Unmatched warranty

Cummins® ‘K50 series’ diesel engine generating sets are a truly cost effective solution to long term power need backed by industry best 2 years / 5000 hrs warranty for the entire generating set.

Cummins advantage

Special features of Cummins® ‘K50 series’ engines like STC (Step Timing Controls) injectors, low temperature aftercooler, square cumbustion chamber, optimised turbocharging and precision heavy duty camshaft make these engines the ultimate in exceptional fuel efficiency all across the operating range.

Single source power assurance

Design, manufacture and testing of engine, alternator, enclosure and other accessories is done by Cummins India/ Channel partners (Powerica Limited) for that optimum performance integrity and is backed by countrywide product support network with single source responsibility for the entire package.

PowerCommand® genset controls – PCC 2100

The PowerCommand® 2100 control, is a micro processor based generator set monitoring, metering, protection and control system. It offers advanced levels of functions for reliability and optimum genset performance. An extensive array of integrated standard control and digital display features eliminate the need for discrete component devices such as the voltage regulator, governor control and protective relays. The control system has easy servicing capabilities that allow system parameters to be interrogated, monitored and adjusted with a PC.

Features

  • Digital governing
  • Digital voltage regulation
  • AmpSentryTM protection for true alternator O/C protection on PCC 2100/ 3100 for solo/ paralleling applications
  • Analog/ bargraph / digital AC output metering
  • Battery monitoring system to sense and warn against a weak battery condition
  • Digital alarm and status message display
  • Genset monitoring : Displays status of all critical engine and generator set functions
  • Smart starting control system : Integrated fuel ramping to limit black smoke and frequency overshoot
  • Advanced serviceability
  • PowerCommand® network capability (optional)

Digital voltage regulation

PowerCommand® 3100 paralleling genset controls (optional)
In addition to the features described above, the PowerCommand® control with digital paralleling features eliminates the need for separate paralleling control devices such as synchronizers and load sharing controls, and KVAR / power factor controls. Besides this, features like synchronizing*, including import/export controls for paralleling with an infinite (utility/mains) bus and the ability to control the load on the generator set when paralleled with utility or mains are also built into the PowerCommand® control.
