Application — Communication equipment power
Requirement — The request was to consolidate AC220V mains power for communication equipment power into a single power unit.
Solution — We configured a Li-ion 3S pack (DC 10.8V, 2,056Wh) together with an AC220V 2kW inverter.
Result — The integrated build in an approx. 20kg housing met the 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.
