diymore | DC3.7‑5V Powered Module 4000V High Voltage Capacitor UV Light Bead Diode Reverse Connection Protection for Mosquito Killer

Features1. Supports DC 3.7V–5V power supply, compatible with a variety of power sources2. On-board dual high-voltage capacitors provide powerful, stable, and durable output3. Purple light actively attracts mosquitoes; uses a purely physical method of extermination that is harmless and odorless4. Reverse polarity protection prevents the board from burning out if the positive and negative terminals are connected incorrectly, ensuring peace of mind during DIY assembly5. High-power design with excellent heat dissipation allows for long-term operation, making it ideal for DIY projectsProduct DescriptionThis mainboard is specifically designed for mosquito-killing lamps. It supports a wide input voltage range of DC 3.7V–5V and is compatible with various power sources, including lithium batteries, USB power supplies, and power banks. Equipped with dual onboard high-voltage capacitors, it delivers a powerful output. When paired with ultraviolet light-emitting diodes (LEDs) that actively attract mosquitoes by exploiting their phototaxis, it achieves highly efficient, purely physical mosquito elimination that is harmless and odorless. The circuit board features a high-power design and is equipped with a reverse-polarity protection diode, ensuring it won’t burn out even if the positive and negative terminals are reversed. It is safe, reliable, and particularly suitable for DIY assembly.ParameterCapacitors: 4000V + 4000V Ultraviolet Light: Built-in UV lightInput Voltage: 3.7–5.5V (recommended not to exceed 5V)Precautions1. The input voltage for this mainboard must not exceed 5.5V; otherwise, there is a 5% risk of capacitor failure. Since an additional 0.1V in input voltage results in several hundred volts of additional high voltage, it is easy to exceed the capacitor’s load capacity. Some USB chargers are rated at 5V but actually deliver 5.2V or higher (as measured by a multimeter).2. Assembly should be performed by individuals with basic electrical knowledge, and proper insulation protection should be used during operation.3.
