Instructions for Use

1. Power Input:

   • Connect the input voltage (9V to 36V) to the VIN and GND terminals.
   • Ensure the polarity is correct to avoid damage.

2. Power Output:

   • Connect the load to the VOUT and GND terminals.
   • The output voltage is fixed at 5V and can supply up to 2A of current.

3. Mounting:

   • For through-hole mounting, insert the pins into the PCB and solder them.
   • For surface mount, place the component on the PCB and reflow solder.

4. Operating Environment:

   • Operate the device within the temperature range of -40掳C to +85掳C.
   • Avoid exposing the device to excessive humidity or corrosive environments.

5. Protection Features:

   • The DK-440 includes overvoltage, overcurrent, and short circuit protection.
   • In case of a fault, the converter will automatically shut down to prevent damage.

6. Storage:

   • Store the device in a dry, cool place away from direct sunlight and extreme temperatures.

7. Troubleshooting:

   • If the output voltage is not stable, check the input voltage and connections.
   • If the device overheats, ensure proper ventilation and reduce the load if necessary.
