Low Voltage Capacitors

Power quality is becoming increasingly essential, and power factor correction (PFC) will be implemented on a larger scale in the future. Enhancing power quality—by improving the power factor—saves costs and ensures a quick return on investment. In power distribution, particularly in low- and medium-voltage networks, PFC targets the power factor (cos ø) and optimizes voltage stability by generating reactive power, which improves voltage quality and reliability at the distribution level.

INDTECH Power Capacitors are manufactured to the highest quality standards, adhering to international specifications such as IEC EN 60831-1/2 and CE marking. They also comply with Indian standards (ISI) and other relevant industry requirements. Furthermore, we offer a dedicated series designed specifically for global market demands.
