Power inverter sockets


  • Intelligent integrated circuit control
    Unique front and rear dual soft start technology, CPU core, SPWM pulse width control technology, special constant power technology, anti-reverse diode technology.
  • Pure sine wave
    100% pure sine wave output, low distortion, waveform and main power line AC waveform are basically the same, equipment accuracy is small, low interference, low noise, strong load capacity, can meet any type of AC load, without damaging the load.
  • Imported parts
    The materials are imported components, and the panel uses double-sided circuit boards to ensure high quality and high performance of the products, and to match the excellent quality of the detailed molds.
  • Aluminum alloy casing
    The surface of the aluminum alloy shell is sprayed and anodized, which is small in size, elegant in appearance and easy to carry.
  • Working instructions intuitive working state
    When the inverter undervoltage/overvoltage, overload, overtemperature, short circuit, the LED indicator lights.
  • Multiple protection functions
  • Fault warning/buzzer alarm reminder
    When the inverter high voltage, low voltage, over temperature, overload protection function is turned on, once the protection of the inverter is triggered, the inverter disconnects the power supply and the load enters the protection mode for the first time, and issues an alarm through the buzzer alarm device. Make your use more secure.

Pure sine power inverter applications

Tips: Is Car Power Inverter Harmful to The Car Battery?
There will be no impact, but the charging time is long, the quality of the car inverter is good, or the output is unstable. In addition, it is recommended to take a route for the inverter in the car alone, because the cable of the cigarette lighter interface is relatively thin, and the inverter must have a switch and a fan.
