DC3.7-5V Mosquito Killer Circuit Board with Anti-Reverse Diode for UV Bug Zapper Mosquito Lamp Replacement Part leírása

1. Supports 3.7V-5V power supply; compatible with various power sources.
2. Features onboard dual high-voltage capacitors for powerful, stable, and durable output.
3. Uses UV light to actively attract mosquitoes; purely physical elimination method-harmless and odorless.
4. Includes reverse polarity protection; the board will not burn out if positive and negative terminals are swapped, ensuring safer DIY assembly.
5. High-power design with excellent heat dissipation; suitable for continuous operation and ideal for DIY projects.

Product Specifications
Capacitors: 4000V + 4000V
UV Light: Built-in UV light
Input Voltage: 3.7-5.5V
Precautions
1. The input voltage for this motherboard must not exceed 5.5V; otherwise, there is a 5% risk of capacitor failure (explosion). An increase of just 0.1V in input voltage can raise the high-voltage output by hundreds of volts, easily exceeding the capacitors' rated limits. Note that some chargers labeled as 5V may actually output over 5.2V (verify with a multimeter).
2. Assembly should be performed by individuals with basic electrical knowledge; ensure proper insulation and safety precautions during operation.
