Crotech Range Extender (1ph – 1ph) is an add-on unit, which ensures satisfactory performance of the UPS, even when the Mains Dips upto 130VAC. This ‘easy to install’ Interface between Utility and the UPS input, helps conserve the battery life and thus, ensures full rated back up for longer periods of usage.
