Application — Motor drive power
Requirement — This motor drive power application also required 12V·3.7V regulated auxiliary power.
Solution — We integrated 12V·3.7V regulated DC-DC converters into a Li-ion 3S pack (DC 10.8V, 136Ah).
Result — The integrated build in an approx. 10kg housing met the motor drive power specification.
If you are considering a custom build to a similar specification, submit a requirements sheet. Our engineer will review it and respond.
