Inverter output function:
Convert the battery's DC power into pure sine wave AC power. After turning on the "IVT SWITCH" on the front panel, the inverter outputs it through the "AC OUTPUT" on the rear panel.
Automatic voltage regulation function:
The gadget can automatically stabilize the output when the load varies within the rated power and the battery voltage shifts between the undervoltage and overvoltage points.
Overvoltage protection function:
When the battery voltage is greater than the "overvoltage point", the device automatically cuts off the inverter output, and then the front panel displays "overvoltage", the buzzer alarms for 10 seconds, and when the voltage drops to the "overvoltage recovery point", the inverter resumes work.
Undervoltage protection:
The inverter will automatically shut off its output if battery voltage drops below a threshold predetermined by the manufacturer. The LCD will display an "undervoltage" reading and the buzzer will sound for 10 seconds. As soon as battery voltage rises above the manufacturer's "undervoltage recovery voltage," the inverter will begin functioning again. A switching device will be able to switch to AC power whenever the inverter goes into "undervoltage mode."
Overload protection function:
When the output power of the AC load exceeds the rated power, the inverter output is automatically cut off, the front panel LCD displays "overload", and the buzzer sounds an alarm for ten seconds. At this time, press "Inverter switch (IVT SWITCH)", and the "overload" display disappears. If the machine needs to be restarted, it must be checked and confirmed that the load is within the allowable range, and then turn on the "Inverter switch (IVT SWITCH)" to restore the inverter output.
Short circuit protection function:
When a short circuit occurs in the AC output circuit, the device can automatically cut off the inverter output. At this time, the front panel LCD displays "overload" and the buzzer sounds an alarm for ten seconds. Turn off the front panel "Inverter switch (IVT SWITCH)", and the "overload" display disappears. If you need to restart the machine, please check whether the output line is normal, and then turn on "IVT SWITCH" to restore the inverter output.
Overheat protection function:
If the temperature underneath the cover of the control unit reaches excessive levels, the device will deactivate it's output to the inverter. Once that occurs, an "overheating" message will appear on the LCD screen and an alarm tone will sound for 10 seconds. Once the temperature has returned to normal, the inverter's output will resume proper operation.
Battery reverse connection protection:
The device has a comprehensive reverse connection protection function for the battery. When the positive and negative polarities of the battery are reversed, the internal fuse of the chassis will automatically blow to avoid any damage to the battery and the device. Battery reverse connection is still strictly prohibited.
Optional AC switching function:
If the AC switching function is selected, when the battery is undervoltage or the inverter fails, the device can automatically switch the load to AC power supply to ensure the stability of the system power supply. When the inverter resumes normal operation, it will automatically switch back to inverter power supply.
