Application — Industrial special-equipment power
Requirement — The challenge was to handle 12V regulated auxiliary power within one pack in the industrial special-equipment power application.
Solution — We built a 12V regulated DC-DC converter into a Li-ion 14S pack (DC 50.4V, 6.8Ah).
Result — The integrated build in an approx. 4kg housing met the industrial special-equipment power specification.
If you are considering a custom build to a similar specification, submit a requirements sheet. Our engineer will review it and respond.
