Possible applications: The operation of computers, radios, televisions, videos, lights, fans, hand-el. tools etc. in motor vehicles with 24V battery voltage Advantages of the device: The stabilized output voltage is independent of input voltage. The output voltage has a sinusoidal output - can be connected to sensitive appliances that with conventional drives do not work correctly. Standard drives have sawtooth output voltage and this can cause interference. When reduced voltage on the battery you will hear a warning tone when another voltage drops below 20V, the inverter shuts down. When increasing the voltage itself closes. So there is no battery.
