Sai electricals presents an automatic power factor controllers. Powerware apfc is a 3-phase multiple capacitor banks reactive compensator having micro computerised control relay. It has a target power factor round the clock. Apfc conservers energy and avoids detrimental effects of over current, hence supports the equipment. Its special features are automatic control of up to 12 capacitor banks; modular construction; capacitor; intelligent operation; computer compatibility; multiple digital displays; dust protection; safe, reliable, low loss and protection and alarm annunciation. Its advantages are as follows: increased equipment life; saves penalty; earns rebate; reduced generator load; long capacitor life; energy saving; longer life from conductor switchgears and contacts; and short pay-back period.
