Diesel generator set S series

Latest technology product :

Value for money

The Cummins ® ‘S series’ engine powered diesel generating sets offer the best fuel economy, best warranty terms and lowest cost of maintenance thereby proving to be the most economical power solution. With the superior designed engine and world class Cummins Generator Technologies (Stamford) make alternator, the gensets come equipped with Cummins corporate genset controller for ease of use and monitoring generator performance.

Silent, compact and light weight

The Cummins ® ‘S series’ DG sets are smaller and lighter than any other DG set in it’s class, thus giving you the advantage of optimizing your valuable space.

Environment friendly power

The Cummins ® ‘DXP series’ base DG sets are available with the lowest noise levels in it’s range and are CPCB certified for emissions compliance, thus offering you environment friendly power.

The genset powered by the reliable Cummins ® ‘X series’ diesel engine meets stringent exhaust emission tests as per MOEF norms without sacrificing fuel efficiency at normal operating loads.

Unmatched warranty

The Cummins ® ‘S series’ DG sets are backed by the industry acknowledged best-in-class comprehensive warranty on the entire package including rubber components.

Lowest Operating Costs

All elements of the Cummins ® ‘S series’ DG sets are designed from the start to work together to maximize efficiency, even at part loads, thus offering you the advantage of lowest operating costs.

P1′ frame alternator on 35 & 40 kVA node provides improved serviceability. It is designed for ease of assembly, Light in weight. This alternator is also available with upfitable option of EBS (Excitation Boost System) for good motor starting and short circuit maintenance.

Single source power assurance

The rugged and reliable Cummins ® ‘S series’ DG sets are unique, because all the major components – the engine, alternator, control system and canopy are designed, manufactured and tested by Cummins India/ Channel partners(Powerica Limited). This, complemented by the largest customer support network in India, capable of providing round-the-clock service and spares support, offers you SINGLE SOURCE POWER ASSURANCE from the world leaders in power generation

Mounting arrangement

Engine and alternator are mounted on a common MS fabricated base frame with AVM pads.

Control panel

The control panel is manufactured with 14/16 gauge CRCA sheet and is powder coated for a weather-proof and long lasting finish.

The control panel consists of following parts:

PS0500 Controller
Aluminum bus bars with suitable capacity with in/outgoing terminals
Indicating lamps for ‘Load On’ and ‘Set Running’
Instrument fuses duly wired and ferruled
MCCB of suitable rating with overload and short circuit protections

PS0500 Genset controller

Cummins PowerStart™ PS0500 control is a microprocessor based generator set monitoring and control system. The control provides a simple operator interface to the generator set, manual and remote start/ stop control, shutdown fault indication, and an LCD hour counter. The integration of all functions into a single control system provides enhanced reliability and performance compared to conventional generator set control systems. This control has been designed and tested to meet harsh environment in which gensets are typically applied.

Engine controls

PowerStart operates on 12 VDC batteries
Auto start mode accepts a ground signal from remote devices to automatically start the DG set. The remote start will also wake up the control system from sleep mode.
Engine Starting – The control system supports automatic engine starting, Primary and back up start disconnects are achieved by battery charging alternator feedback or main alternator output frequency.
Controller provide configurable time delay of 0-300 secs to start after remote start signal and time delay of 0-600 secs prior to shutdown after stop signal.
Sleep mode increase battery life. Configurable current settings from low to minimize current draw when genset is not working.
