Usage Tips:1. High-power design: maximum power up to 60W, to efficient mosquito control, fast return to power 2. Low-power standby: standby current is less than 5mA, no-load current measured 150mA, energy-saving and power-saving 3. Overheating automatic protection: MOS tube overheating automatic protection to prevent damage and prolong service life Product Name:High Power Boost Module Power supply voltage:DC 2.8-4.2V. Input current:20A (power lithium battery) Maximum power:60W Output voltage:DC 4000 V (3.3V is about 3kv under 4.2 V power supply). Description: This boost module is suitable for transforming the powerful electric mosquito beat, has the advantages of high voltage, fast return, high power, small size, strong versatility, short-circuit does not burn, no-load power consumption is small, no-load does not heat, overheating automatic protection. Note:Module work with a very slight electromagnetic squeak is a normal phenomenon, the module on the small switch connecting wires as short as possible, when the big bugs (such as: large moths hornets) sticking in the electric mosquito swatter network, a long period of time to continue to full-power may trigger the module overheating protection, when overheating protection is ineffective when you the switch, and the work of the indicator light does not (green), so that the module to rest for a few seconds to work normally, and do not recommend continuous and continuous use of short metal, no-load power consumption, no-load automatic protection. It is not recommended to continuously discharge the large capacitor with a short metal connection, which damage the life of the large capacitor.
