LAK SERIES - AC INPUT LIPO CHARGERS
Versatile LiPo industrial battery chargers
The LAK product line is designed for applications requiring AC input. This series is especially suited for alternative energy power sources including fuel cell, solar and wind power, onboard vehicle applications, and many other systems. The standard AC input range is 85VAC-140VAC. However, we offer an extended input/output range up to 300VAC. The LAK series is available in both waterproof and fan cooled versions. User defined optional relay signal contacts are available upon request.

LAK part numbers are easily configured. Model numbers are in the form LAw-xSyy-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 LAK-4S2.5-01-R denotes a standard 85-140v AC input, four series cells and 2.5 amps of charging current. The suffix (R) is required for customization definition (see datasheet) but not required for standard units.
