Features of High Frequency Power Inverter

Main features of high frequency power inverter:

Using CPU control, the circuit is simple and reliable;
Using SPWM pulse width modulation technology, the output is a pure sine wave with stable frequency and voltage regulation, filtering out noise and low distortion;
Built-in bypass switch, fast switching between mains and inverter;
Main power supply type and battery main supply type:
Mains supply type: when there is mains, it is in mains output, and automatically switches to inverter output when mains input fails;
Main battery supply type: when there is commercial power, it is in the inverter output, and automatically switches to the commercial power output when the DC input fails;
It is allowed to cut off the DC in the power-on state, and automatically switch to the mains bypass, without affecting the power supply of the load, and it is convenient to maintain and replace the battery;
If the battery voltage is too high or too low, the inverter power supply will turn off the output. If the battery voltage returns to normal, the power supply will automatically restore the output;
When the load is overloaded, the inverter power supply turns off the output. After 50 seconds after the overload is eliminated, the power supply automatically resumes the output. This function is especially suitable for unattended communication base stations;
Support communication function, provide RS232 interface (PIN2, 3, 5), use monitoring software to understand the working condition of power supply in real time; (Note: 500VA models in this series do not have this function at the moment)
Provide two sets of passive dry nodes, respectively used for DC input fault (RS232 PIN6, 7) and AC output fault alarm (RS232 PIN8, 9) (Note: 500VA models in this series do not have this function)
Supports no-DC power-on function, and can run in the state of only commercial power. This function allows the inverter power supply to be put into use first, and then the battery is installed. (Note: 500VA models in this series do not have this function at the moment)
