India continues to be dogged by power and voltage fluctuation problems, particularly in rural segments, causing the voltage sta­biliser business to flourish. “Looking at the power problem woes, it is expected that the market will be good for another five to six years at least. The present demand for voltage stabi­lisers is increasing by 10-15 per cent per year,” says Anoop Lalwani, CEO, Sai Enterprises. The size of the voltage stabiliser market at present is around Rs 10,000 million.

Wednesday, March 18, 2009: Voltage stabilisers are used in almost all applications where sta­bilised power supply is required. The various kinds of voltage stabilisers include power line conditioning systems (PLCS), automatic voltage stabilisers, static voltage stabilisers, CVT, servo voltage stabilisers, constant voltage constant frequency (CVCF) stabilisers, automatic solid state stabilisers, servo stabilisers and magnetic voltage stabilisers. “In the Indian market, the fast moving stabilisers are ones that are relay controlled and the servo stabilisers. The con­stant voltage transformer (CVT) even though is costly, offers much better features and functionality,” informs Lalwani.

The cost factor

The chief expenditure involved in stabilisers is the cost of input raw materials required like electronic circuits, transformers, copper, iron, etc. According to Anoop Lalwani, CEO, Sai Enterprises, “The cost of stabilisers is dependent on the basic cost of raw materials. However, since our company’s manufactural portfolio does not only consist of stabilisers, but also transformers and electronic controllers for the stabilis­ers, we can provide customers with stabilisers of exemplary quality at competitive prices,” he said. Sunil Bafna, proprietor, Pixel Electro Controls, explains, “There are basically three main raw mate­rials—copper, core and electronic components. Each one of these three variants is subject to the whims of the international market. In the recent past, their rates have seen sporadic ups and downs, causing manufacturers to be confused about issues like cost pricing.

Future prospects

The latest stabilisers are microcontroller-based and insulated gate bipolar transistor (IGBT) controlled. “They are of the totally solid state variety, albeit a little expensive and not meant for general consumption or home usage,” in­forms Lalwani. Throwing light on a worrying trend that has recently challenged the industry, Bafna says, “Nowadays, a few companies are launch­ing appliances that are independent of voltage stabilisers, which has had a negative impact on a few segments.”

The future of stabilisers lies in small-sized stabilisers, speciality stabilisers and low-cost stabilisers. Elaborates Lalwani, “The future is in size-reduction of various models and promo­tion of special types of stabilisers like CVT for certain types of applications and in introducing low-cost stabilisers.” Shaji S, director, Conver­gence Power Systems Pvt Ltd, adds, “The latest version of voltage and frequency stabilisers, that is, CVCF are used mainly in the food processing and medical industries. The latest version of PLCS is also available in the market.”
