    Protection Functions & Applications

    pure sine wave power inverter protections

    Pure sine wave power inverter applications

    • Reverse Polarity Protection
      Auto protection when input positive and negative polarities are reversely connected – The fuse blown out.
    • Short Circuit Protection
      Automatically self-protect when short circuit occurs – Red LED light ON.
    • Low Voltage Protection
      Automatically protect when in low voltage – Alarm first, the voltage continuously reduces, the red light is on and the inverter shuts down.
    • Over Voltage Protection
      Automatically protect when in high voltage – Red LED light is on, and the inverter automatically shuts down.
    • Over Temperature Protection
      Automatically self-protect when at high temperature – Alarm first, the temperature continuously rises, the red light is on and the inverter shuts down.
    • Overload Protection
      Automatic self-protection when there is overload – Red LED light is on and the inverter automatically shuts down.

    Tips: Inverters versus converters

    Similarities between the inverter and converter

    1. Both are voltage inversion.
    The inverter and the converter have the same function and both are to realize the voltage inversion. The power inverter converts the 12V/24V/48V DC from the battery or battery bank to high-frequency, high-voltage AC electricity (110V/ 120V/ 220V/ 230V/ 240V etc.), while the converter converts the AC voltage of the grid into a stable DC power.

    2. Both adopt PWM technology
    Both of them use pulse width modulation (PWM) technology, and the core part is a PWM integrated controller.

    Differences between the inverter and converter

    1. The roles are opposite
    Although inverters and converters are to achieve voltage inversion, but the former is to convert low-voltage DC into high-frequency high-voltage AC, while the latter is to convert AC to DC.

    2. The chip is different
    The power inverter uses the chip with operating voltage range of 3.6V-40V, and the internal also set the regulator, error amplifier, oscillator, short-circuit protection circuit, low voltage protection circuit and so on. But the converter is different.

    In this video, ATO makes a simple test on the input and output voltage of 1000W 24 DC to 220V AC pure sine wave power inverter. And, this power inverter is used to power a cell phone and a fan which work normally.

    How to Diagnose Inverter Problems and Repair
    An inverter is a power conversion device. The basic working principle of an inverter is to convert direct current into high-frequency, high-voltage alternating current through pulse width modulation (PWM) technology. The core part of the inverter is a PWM integrated controller, which is responsible for generating PWM signals and converting DC power to AC power through MOS switching tubes. A blown fuse is one of the most common reasons why an inverter has no output. This video will show you how to perform a simple diagnosis of a failed inverter and how to fix the problems.

    ATO Responded
    Yes, just select 48VDC for input, so the inverter can accept 40.2 - 60.4V DC voltage in input.
    Works great as expected.
    Works great as expected. I use this item in my car for running my laptop and phone and it does a good job. Really recommended.
