The learning acquired over 30 years has been harnessed to offer superior quality product at competitive price.Our product comprehensively fulfilled the request of national and international standard specification.Being an iso 9001:2000 certified co.We make sure that each and every product meets the customer requirement.
Quality policy: BELTRONICS is committed to provide optimum quality and timely and cost effective manner with care to society & environment &
ensure continual improvement in its product,process, systems and customer satisfaction by meeting the expectation.
Voltage fluctuation is common phenomenon in every part of the country. All electrical equipments and Machines are designed and
manufactured at 230 V(single phase)& 400V (3 phase).But because of irregular load pattern on HT distribution lines,no electrical
authorities ensures constant voltage to the customers, results high voltage variation is witness,generally voltage is low during day time and
high during night time.Moreover in holidays, peak hours,rainy days and when agriculture and industrial load is switched off,voltage
rises sharply which is more dangerous.
DESCRIPTION OF AUTOMATIC VOLTAGE STABILIZER
1.LINEAR TYPE PLUS/MINUS TYPE VERTICAL ROLLING CONTACT TYPE REGULAR.
2.DOUBLE WOUND BUCK BOOST TRANSFORMER.
3.ELECTRONIC CONTROL CIRCUIT AND METER PANEL
The buck/boost& Regulator transformer windings are built for paper covered copper conductor dried in oven.The cooled rolled grain oriented silicon steel lamination (CRGO) to minimize iron losses.All component of equipment mounted on framework of M.S. Hosing are fitted with cool pipes to provide natural cooling.
