Application — Communication equipment power
Requirement — The customer needed a power source for communication equipment power with regulated auxiliary power.
Solution — We combined a regulated DC-DC converter into a LiFePO4 8S pack (DC 25.6V, 12Ah) as a single unit.
Result — A discharge configuration rated at 12A maximum (30A peak @ ≤1.5s), housed in approx. 5kg, completes communication equipment power in a single pack.
