3. Usage Instructions

How to Use the XKT203-33 in a Circuit

1. Power Supply:

   • Connect a DC power source (e.g., a 3.7V Li-ion battery or a 5V DC adapter) to the VCC and GND pins. Ensure the input voltage is within the specified range (3.7V to 7.4V).
   • Use a power source capable of supplying at least 1A of current for optimal performance.

2. High-Voltage Output:

   • Connect the HV+ and HV- terminals to the load (e.g., the metal grid of a mosquito zapper). Ensure proper insulation and spacing to prevent arcing or accidental contact.

3. Safety Precautions:

   • The output voltage can reach up to 3000V, which is dangerous. Handle the module with care and avoid direct contact with the high-voltage terminals.
   • Use insulated wires and ensure the circuit is enclosed in a non-conductive housing.

4. Testing the Module:

   • After connecting the module, power it on and verify the high-voltage output using a high-voltage probe or by observing the operation of the connected load (e.g., a spark or zap sound in a mosquito zapper).

Important Considerations and Best Practices

• Heat Dissipation: The module may heat up during operation. Ensure proper ventilation or heat sinking if used for extended periods.
• Load Resistance: Avoid shorting the high-voltage output terminals, as this can damage the module.
• Insulation: Use high-voltage-rated wires and components to prevent arcing or accidental discharge.
• Polarity: Ensure correct polarity when connecting the input voltage. Reversing the polarity may damage the module.

4. Example Circuit with Arduino UNO

The XKT203-33 can be controlled using an Arduino UNO to enable or disable the high-voltage output. Below is an example circuit and code:

Circuit Diagram

• Connect the VCC and GND pins of the module to a 5V DC power source.
• Use an NPN transistor (e.g., 2N2222) to control the module's power supply via a digital pin on the Arduino.
• Add a 1kΩ resistor between the Arduino digital pin and the transistor's base.

Arduino Code

// XKT203-33 High-Voltage Module Control with Arduino UNO
// This code toggles the high-voltage module ON and OFF every 5 seconds.

const int controlPin = 7; // Digital pin connected to the transistor base

void setup() {
  pinMode(controlPin, OUTPUT); // Set the control pin as an output
  digitalWrite(controlPin, LOW); // Start with the module turned OFF
}

void loop() {
  digitalWrite(controlPin, HIGH); // Turn ON the high-voltage module
  delay(5000); // Keep it ON for 5 seconds
  digitalWrite(controlPin, LOW); // Turn OFF the high-voltage module
  delay(5000); // Keep it OFF for 5 seconds
}

Note: Ensure the high-voltage module is properly insulated and enclosed when testing with Arduino.
