Application — PC and controller power
Requirement — The customer needed a power source for PC and controller power with 24V regulated auxiliary power.
Solution — We combined a 24V regulated DC-DC converter into a Li-ion 7S pack (DC 25.2V, 13.6Ah) as a single unit.
Result — The integrated build in an approx. 3.0kg housing met the PC and controller power specification.
If you are considering a custom build to a similar specification, submit a requirements sheet. Our engineer will review it and respond.
