Description
Overview
This step-down DC–DC converter turns an input of 18–90 V DC or 72 V DC into an output of 12 V or 24 V. This listing contains 3 models with output currents of 40–60 A.
Every value below is stated by the supplier for that exact model and has not been independently tested by PVShop. Choose a model above to see its full specifications and download its datasheet. Price and availability depend on your delivery country; the selector above shows the models available for it.

≈ Calculated from output voltage × current; not a separate power rating.
Choosing the right model
- Some models document only a nominal input voltage. Check the exact model’s datasheet for its permitted input range before connecting a battery system, whose voltage rises while charging.
- Keep your continuous load comfortably below the rated output current of the model you choose.
- On a step-down converter the input current is lower than the output current. Size the cables and fuses on each side for the current on that side, and fit the input fuse close to the battery.
- Each model has its own PVShop datasheet. It appears with the full specifications when you select the model above.
