The EA16 AVR is an update of the EA15A AVR. It is similar to the original EA15A in power and voltage
sensing capabilities but with new enhanced paralleling functions; the user can now select the CT inputs either
1 & 5 Amp or use new A1 & A2 analogue signal inputs terminals for use with PLC paralleling controls. It has
new over-voltage excitation safety circuits to prevent damage caused by the accidental detachment of the
sensing wires or irregularities on the generator’s excitation circuits.

Since establishment in 1985, Guangdong ALI Testing Equipment Co., Ltd, a wholly-owned subsidiary of GSKA Group has been providing a wide and complete range of products and services to the society. GSKA has now 16 offices, warehouses and service centres in China, with head office loCAT-partsed in Hong Kong. There are more than 100 employees in GSKA Group, and we are expanding into many industries with rapid expanding pace of China.

There are mainly 4 departments in GSKA Group, namely:

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 manufacture electric locks in China. Since then, we have been exported products to the Middle East, South Asia and Africa. Our market is expanding each year and we are looking for more distributors in different countries to be our business partners. Besides electric locks and accessories, we have also developed our own access control system by our software team. The system includes smart card solution and also biometric access control, such as hand-key, fingerprint and facial recognition. Our EC-PAYROLL system has been widely used in many factories both in Hong Kong and mainland China.

After all, GSKA has an objective of "Always Provide the Best" and we shall consistently provide high quality products and reliable services to our worldwide customers. We are looking forward to making good business with our partners
