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 pure sine wave inverter 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 sine wave 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.

Tips: What is the Differences Between the Inverter and the Frequency Converter?

  • A frequency converter is a component used to change the frequency of an alternating current, and an inverter is a component used to convert direct current into alternating current.
  • The inverter should have a part to adjust the frequency, and the inverter only needs to have a fixed output frequency.
  • The inverter converts DC power (battery, battery) into alternating current, and the frequency can also be adjusted, the inverter converts the input AC into the AC output of the desired frequency. The principle is cross-straight-crossing or cross-crossing, and the form of cross-right-crossing is more common. AC-DC-AC first converts AC power to DC, then DC to AC, which is Rectification + Inverter.

Efficiency pure sine wave inverter
This pure sine wave inverter is designed to be very safe to use. I purchased 50 pure sine wave inverters and it didn't cost me a lot of money. I need a pure sine wave inverter to run the electric pump. Inverter works very well, look very pretty.
