MD-Series 20 KVA DG Set

Meeraco diesel generating sets are powered by the renowned Meeraco diesel engines conforming to the latest CPCB emission norms, are environment friendly and engineered to run under strenuous conditions.


Standard scope

Engine: Meeraco diesel generating sets, powered by Meeraco engines of “ MD series” , are rated at 1500 RPM. The engines are radiator cooled, four stroke and multi-cylinder, conforming to BS 5514 / ISO 3046 / ISO 8528.

The scope of supply includes:

  • Electrical starter motor 12V DC

  • Battery charging alternator

  • Bosch fuel system with mechanical governor

  • Dual fuel filter

  • lub oil filter

  • Residential silencer

  • Dry type air cleaner

  • Coolant Reservoir

  • Shut-off coil with safeties for LLOP/HWT

  • First fill of lube oil and coolant

Meeraco Series Engine Features And Benefits :

  • Meeraco “MD 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.

  • Low exhaust emission , meets the next generation CPCB norms thus offering you environment friendly power.

  • Wet liner construction eliminates time consuming and expensive block re-boring during overhauls.

  • Deep skirted crank case design , high degree of rigidity and ruggedness.

  • Easy accessibility of all maintenance parts.

  • High degree of commonality of components over entire range.

  • Individual cylinder head design , savings on maintenance cost and time.

  • Simple in – line fuel injection pump.

  • High reserve power margins for providing higher block load capability.

  • Very low basic engine noise level.

Alternator: Meeraco alternator, suitable for operation at 1500 RPM, 415 Volts,0.8 pf (lag) suitable for 50 Hz, 3 phase & 1 phase, 4 wire & 2 wire system. The alternator is designed and built to withstand tropical conditions. The alternator generally conforms to IEC 34-1/34-2 , BS 4999/5000 and IS: 4722-2001 with enclosures rating IP 23 is the standard version, satisfying IEC 34-5/IS : 4691/DIN VDE 0530-5 requirements. The Alternator is dynamically balanced , brushless type, screen protected, revolving field, self excited, self regulated through an AVR. The alternator has the following features:

  • +- 1.0 % Voltage regulation (max.) in static conditions

  • IP: 23 protection with insulation class H

  • Permissible overload of 10% for one hour in 12 hours of operation.

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

Control Panel: The gensets are supplied with inbuilt control panels complete with internal wiring/cabling having necessary displays and protections for ease of operation and maintenance. The control panel is manufactured with 14/16 gauge CRCA sheet and is powder coated for weather-proof and long lasting finish.

The control panel consists of the following parts:

  • DES - 09 Controller : Key switch & Remote Start / Stop generator set controller.

  • Multifunction meter displaying the below parameters :-

  • -Voltage -Current -Frequency -Water temp. -Oil pressure. -Low fuel, -RPM , -Battery Voltage, -Running Hrs. , ---Service Hrs.

  • Aluminum bus bars with suitable capacity with incoming/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

  • Current Transformers.

DES-09 Genset Controller : DES-09 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.

Control System :-The standard control system includes all the functions necessary to locally or remotely start and stop and protect the generator set.

Key Switch : OFF/ ON /START – In the OFF mode the generator set is immediately shut down, if running , and cannot be restarted. It also resets any faults. In this mode all power is removed from the control and its output. In ON position the control is powered and the start/stop push buttons become enabled.

LED Indicating Lamps :- The control includes LED lamp indication for the following functions :-

-Failed to start -Overspeed/Underspeed -Low oil pressure

-High water Temp. -Battery Chg. Alt. fail -Radiator water level -Over voltage -Under frequency -Over frequency

-Under voltage -Over current

LCD engine hour counter :- The control includes an LCD engine hour counter. The counter will increment whenever the engine is running.

Engine Safety and Protection Features :

Failsafe system with special sensor to safeguard Diesel generator against faults like :-

  • Emergency stop: Annunciated whenever an emergency stop signal is received by the control.

  • Low lube oil pressure

  • High water temp

  • Low and high battery voltage

  • Short circuit protection

  • Over speed protection

Alternator Protective functions includes

  • High and Low AC voltage

  • Under and Over frequency

  • Loss of sensing voltage input
