APFC Systems, Thyristor Switched

Udeet Electricals, a registered SSI company accredited with ISO 9001-2000 certification, manufactures Thyristor Switched Automatic Power Factor Correction Systems. Thyristor switching of capacitors for power factor improvement has many advantages over conventional contactor switching. Thyristor switching is highly reliable with minimum maintenance, especially suitable for fast variable loads, where contactor switching systems fail to give desired results. The capacitors are switched at "zero current cross over threshold". Unlike conventional (contactor switched) systems where load correction is slow, in thyristor switched and capacitor APF correction systems the load PF correction is quick and consistently near to the set value. Total PF correction is achieved within few hundred milliseconds. Fast PF correction reduces maximum demand more effectively, hence more savings on account of reduction in MD charges. Also, capacitors are switched through thyristors at "zero current crossover threshold". Hence the capacitor connection to the mains is always smooth, transient free and absolutely without generation of harmonics and voltage spikes. Udeet Electrical is supported by experienced engineers, finance persons like chartered accountants and highly skilled and trained manpower to execute jobs at works and in the field, to render desired results. It complies with the requirements of ISO, strict QC standards are followed at each and every step, with a very clear vision of providing best product to the customers.
