Nuova Elettra Multi SW 1

HIGH EFFICIENCY CHARGER

The MULTI SW1 High Frequency charger results from many years of development and experience as a major supplier to the material handling market. It’s a multi-voltage charger eliminating the need for multiple chargers in a facility. Users can standardize on a single charger from a single source simplifying installation, operation and maintenance. This new charger incorporates in its design the latest High Frequency technology, robust contruction and high reliability. User programmability allows the user to optimize the charge profile (IUIa) for their specific battery and with its advanced features, the charger is programmable to fit any battery size and up to 80V for 3Ph and 48V for 1Ph. Programmable Desulphating charge at constant current is made available.
