APFC Relays
All Products- Pictures
L&T Electrical & Automation (E&A) offers a complete range of Automatic Power Factor Correction (APFC) controllers for industrial and commercial applications that automatically correct the power factor of electrical installations.
The (APFC) controllers enable monitoring of key parameters such as power factor, %I-THD & %V-THD to achieve the desired power factor, which results in energy saving and reduction in electricity bills.
Compact in size, APFC controllers are easy to use and install and, at the same time, it ensures exceptional reliability and efficiency of the electrical system.
