How to Use SMPS_9V_UP15S09: Examples, Pinouts, and Specs

The SMPS_9V_UP15S09 is a Switching Mode Power Supply (SMPS) component that provides a stable and regulated 9V output voltage. This component utilizes the UP15S09 module, which is known for its efficiency and reliability in converting a wider input voltage range to a steady output voltage. Common applications for this SMPS include powering electronic circuits, microcontrollers like Arduino UNO, and other devices that require a 9V power source.

• Output Voltage: 9V DC
• Input Voltage Range: 100V AC to 240V AC, 50/60Hz
• Output Current: Up to 1.5A
• Efficiency: >80% at full load
• Protection: Overcurrent, Overvoltage, Short Circuit, Thermal
• Operating Temperature: -10°C to +60°C
• Safety Standards: Compliant with relevant international standards

1. AC Input Connection:

   • Ensure the power source matches the input specifications of the SMPS.
   • Connect the live and neutral wires to pins 1 and 2, respectively.
   • If available, connect the ground wire to pin 3 for safety.

2. DC Output Connection:

   • Connect the positive output (pin 4) to the positive rail of your circuit.
   • Connect the ground output (pin 5) to the ground rail of your circuit.

• Always disconnect the power before making any connections to avoid electric shock.
• Use a fuse on the AC input for additional safety.
• Ensure proper ventilation around the SMPS to prevent overheating.
• Do not exceed the rated output current to avoid damage to the SMPS.

Q: What should I do if the SMPS is not powering on? A: Check the AC mains connection for proper voltage and ensure the fuse is not blown.

Q: The output voltage is fluctuating, what could be the cause? A: Ensure that the load does not exceed the rated current and that there are no short circuits in your application.

Q: Can I use this SMPS with an Arduino UNO? A: Yes, the SMPS can be used to power an Arduino UNO, which typically operates at 7-12V.

Q: How can I reduce electromagnetic interference (EMI) from the SMPS? A: Use proper shielding and grounding techniques, and keep the SMPS away from sensitive components.

Q: The SMPS is overheating, what should I do? A: Ensure adequate ventilation and check if the load is within the specified limits.

// No specific code is required for powering the Arduino UNO with the SMPS.
// However, ensure that the 9V output from the SMPS is connected to the
// VIN pin on the Arduino and the ground is connected to one of the GND pins.

void setup() {
  // Initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  // Turn the LED on (HIGH is the voltage level)
  digitalWrite(LED_BUILTIN, HIGH);
  // Wait for a second
  delay(1000);
  // Turn the LED off by making the voltage LOW
  digitalWrite(LED_BUILTIN, LOW);
   // Wait for a second
  delay(1000);
}

Note: The above code is a simple blink program to test the power supply functionality with an Arduino UNO. The SMPS_9V_UP15S09 should be connected to the VIN and GND pins on the Arduino for power.
