    FAQ

    Q1: Can I connect multiple dc converters in series or parallel?

    Series connection is not recommended due to voltage imbalance risks. Parallel connection is possible to increase current, but all converters must have matched voltage outputs and current balancing mechanisms.

    Q2: Is dc buck converter compatible with lithium-ion battery systems?

    Yes, as long as the 24VDC input falls within the converter’s input voltage range. However, ensure that the battery management system (BMS) supports the load and has appropriate protections in place.
