400W Step Down Module

400W 12V / 60V 15A Step Down Module

Power Supply Voltage and Current Adjustable DC DC Step Down With Aluminum Heatsink

The potentiometers on the product are multi turn (30 turns).  You may need to turn them a lot to see the voltage change.

Attention this product only steps down voltage. It cannot be used for stepping up voltage.

     400W step down module. The output voltage is at the level of 80% of the input voltage. For this reason the output voltage is at a maximum of 45V levels. Thanks to the high current carrying terminal blocks at the input and output, connections can be made easily. When the device operates, the blue led next to the adjustment potentiometers becomes active.

     There are 2 adjustment potentiometers next to the output terminal block. Voltage and current adjustment potentiometers. These potentiometers are multi turn ( they can turn 20-30 turns.). You must turn the potentiometers a lot to be able to see the effect. You can use it with a constant current output by limiting the output current to a certain value. CV is the voltage adjustment potentiometer. CC is the current adjustment potentiometer

     During battery charging the constant current led on the horizontal board lights up. In this way you can monitor the charging status.

     In places where the air flow is good, it does not need external cooling up to 280W 12A. At higher powers the use of an external fan is required.

     There is a fuse at the module input. If the fuse fails you need to replace it.

Potentiometer Use:

• The potentiometers are multi turn. They can turn 20-30 turns in both directions. Generally the mistake of turning very little and thinking the products do not work can be made. To see the effect it is necessary to turn a lot.
• Turning clockwise; Increases the value for the relevant parameter. For example the voltage increases.
• Turning counterclockwise; Decreases the value for the relevant parameter. For example the voltage drops.
