Precautions for using the module

(1) The module belongs to the step-down type module, the input voltage needs to be greater than the output of more than 1V to stabilize the output.

(2) The heating of the module is mainly determined by the input and output voltage difference and the load current. Please choose and use the power module reasonably. Generally, you need to reserve 30% of the surplus.

(3) The module generates heat during use, please purchasers to enhance heat dissipation according to the actual situation. When carrying a large load, heat sinks, air cooling, etc. can be added appropriately.

(4) When using capacitive or inductive loads, the instantaneous current of the load cannot be too large, otherwise the module may be damaged.

Frequently asked questions

Q: What is the output range of ADJ? What is the output current?

A: The ADJ output range is 1.5V to Vin-1V. The maximum is 3A, and the output current will be less than 3A when the input-output voltage difference is large.

Q: Can the module outputs be connected in parallel or in series?

A: When the output voltages are equal, they can be connected in parallel, but not in series. Each channel is independent, but it will not be isolated and cannot be connected in series.

Q: Is the mounting hole grounded? Can the module output negative voltage?

A: The mounting hole is not grounded, and the module can only reduce the positive voltage and cannot output the negative voltage.

Q: Can the input voltage of 12V work normally?

A: Yes, but the output voltage of ADJ will be a little.
