The Cummins Diesel Generator & DG set 40 kVA is given with power supply options that offer reliable results and are provided best suited for prime-duty applications. With a rated speed of 1500 RPM and compression ratio being 17.5:1 with two-cylinder in line engines, the silent diesel has been found with effective performance. The generator has a cubic capacity of 1.5 L and guarantees stable power output. It operates at 230/415V, 50 Hz with a power factor of 0.8. This generator has a compact structure with dimensions of 7.4 x 3.6 x 5.7 feet and about 1260 kg. It is suitable for use in different installation environments, has a 72-liter fuel tank, and so it can be used continuously for a long time before refueling. The cooling system is liquid-based for the engine to work for a long time and sustain optimal performance. Noise levels are maintained less than 75 dBA at 75% load, making it noise-friendly enough for noise-sensitive locations. A strong 12V D.C. starting system propels the generator, coupled with a reliable battery from Exide Genplus or Amaron. The DSE controller allows for effective monitoring of key parameters, and safe operation is ensured by features such as overload and short-circuit protection. The generator has a body sheet of 1.2 mm in thickness and PU foam of 40 mm in thickness for sound insulation and durability when in use. The silent diesel generator 40 kVA also features automatic shut-downs on over-voltage, low fuel, or emergency stops to make it reliable when operating. Thus, the Silent Diesel Generator 40 kVA is a highly versatile and reliable option for constant power supply in the different commercial and industrial application environments.
