Brushless Generator Automatic Voltage Regulators Leroy Somer avr R438
R448 AVR is powered by two auxiliary windings which are self-sufficient of the voltage match circuit, the first winding has a voltage in proportion to that of the alternator(characteristic shunt), the second has a voltage in proportion to the stator current(compound characteristic: booster effect). The power supply voltage is rectified and filtered before being used by the AVR monitoring transisitor.

1) Construction and Mining equipment
GSKA has been cooperating with many international famous brands in
China, such as Ingersoll-rand, Atlas Copco and Liebherr. Our
products include concrete batching plants, concrete mixers,
hydraulic crawler drills, pneumatic crawler drills, water well
drills, air compressors, road compactors, breakers and various
other equipment. We are major in several industries, such as
hydro-electric power plants, cement quarries, coal mines and
railway systems.
In order to provide a quick response to our customers, we have stocked over US$1.5 Million spare parts of Ingersoll-rand and Atlas Copco in our Chinese warehouse. Recently, we have exported small air compressors, pneumatic crawler drills, water well drills and drilling accessories and spare parts to overseas market.
2) Power Group
GSKA has been supplying CAT-parts and Broadcrown gensets for more than
15 years. Our major customers include Telecoms, Banks, Airports,
Factories and many other sectors in the society. We are also doing
assembly of gensets in China, under our brand name of "GSKA " with ratings from 1KVA to 2000KVA. The quality of "GSKA " genset has won a very good reputation from customers in China and
overseas market.
We are also the specialists for genuine spare parts, such as CAT-parts, Perkins, FG Wilson, Cummins, , Volvo, etc.
Besides gensets, we also provide total solution on the power problems, such as Powerware - UPS, DC system and battery ,lightning equipment and many other electronic products.
3) Security and IT Group
GSKA acquired famous USA brand name Locktronix in 2004 and started
