Application — Industrial special-equipment power
Requirement — This industrial special-equipment power application also required AC220V mains power.
Solution — We integrated an AC220V 6kW inverter into a Li-ion 14S pack (DC 50.4V, 7,056Wh).
Result — The integrated build in an approx. 65kg 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.
