Application — Defense communication equipment power
Requirement — The customer needed a power source for defense communication equipment power with 6V regulated auxiliary power.
Solution — We combined a 6V regulated DC-DC converter into a LiFePO4 4S pack (DC 12.8V, 48Ah) as a single unit.
Result — The integrated build in an approx. 6.5kg housing met the defense communication 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.
