What are the undervoltage protection and overload protection functions of the quality pure sine wave inverter 3000W 12V
Jul 06,2022
There are many functions of the quality pure sine wave inverter 3000W 12V. Today's professional inverter manufacturers will take you to understand the undervoltage protection function and overload protection function of the following pure sine wave inverter.
The first is the undervoltage protection function, which means that when the battery voltage of the quality pure sine wave inverter 3000W 12V is lower than the undervoltage point, the device will automatically cut off the output of the inverter in order to avoid damage to the battery due to overdischarge. At this time, the LCD screen on the pure sine wave inverter 3000W 12V will display "undervoltage", and some will have a buzzer to give an alarm sound for about ten seconds. When the voltage rises to the "undervoltage recovery point", the inverter will resume operation. If a switching device is selected, the quality pure sine wave inverter 3000W 12V automatically switches to the mains output in case of undervoltage.
The second is the overload protection function, which means that if the AC output power exceeds the rated power, the device will automatically cut off the output of the quality pure sine wave inverter 3000W 12V. At this time, the front LCD screen will display "overload", and the buzzer will sound for ten seconds to alarm. Turn off the inverter switch on the front panel and the overload display will disappear. Note that if you need to restart the quality pure sine wave inverter 3000W 12V, you must check that the load is within the allowable range, and then turn on the switch.
