LEF SERIES - DC INPUT LIPO ION CHARGERS
SELECT DC INPUT VOLTAGE
LEF part numbers are easily configured. Model numbers are in the form KEw-xS yy-zz-R. R specifies options and several customization parameters such as temperature compensation, relay contacts and serial bus options. The standard product offerings are shown below and the current ratings. To order a unit with lower current simply replace the current rating of the part number shown as follows (high lint current rating) and show example. Please contact us for any variations required.
For example, the LEF-4S4.3-10-R denotes a standard 38-75v DC input, four series cells and 4.3 amps of charging current. The suffix (R) is required for customization definition (see datasheet) but not required for standard units.
Part Numbering Scheme
