Description
Overview
This step-down DC–DC converter turns an input of 18–36 V DC or 30–60 V DC into an output of 12 V. This listing contains 2 models, all with an output current of 20 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.
Both models in this listing
| Model | Input voltage | Output voltage | Output current | Output power |
|---|---|---|---|---|
| PVS-000389 | 18–36 V DC | 12 V | 20 A | ≈ 240 W |
| PVS-000390 | 30–60 V DC | 12 V | 20 A | ≈ 240 W |
≈ Calculated from output voltage × current; not a separate power rating.
Choosing the right model
- Choose a model whose input range covers the lowest and the highest voltage of your supply, including while it is charging: a nominal 12 V battery system can exceed 14 V.
- 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.
