1. The function of the inverter output
When switch on the inverter on the front panel, the inverter source will change
the DC in the storage battery into sane wave AC of the rated voltage and
output it from the AC socket /terminal blocks.
2. The function of automatic voltage regulation
When the voltage of the storage battery waves between the under voltage
point and the over voltage point and when load changes in the rated power, the
machine is provided with the function of automatic voltage regulation when
the AC outputs.
3. The function of over voltage protection
When the voltage of the storage battery is higher than the voltage point ,the
inverter will cut off the AC automatically, meanwhile, the buzzer will give a
warning; the inverter will not t work again automatically until the voltage
drops to normal.
4. The function of under voltage protection
When the storage voltage is lower than the undervoltage point, this machine
will cut off the inverter output in order not to break the storage battery
because of overdischarge.
5. The function of overload protection
When the AC output power is over the rated power, the inverter will cut off
the AC output automatically, the buzzer will give a long warning, the inverter
will come back to normal only when a person cuts off the switch, repeals the
overload and starts the inverter again.
6. The function of overtemperature protection
If the temperature of the inner case is too high, this machine will cut off the
inverter output automatically, meanwhile, the buzzer will give a warning. The
instrument will start to output AC when the temperature comes back to
normal.
7. The function of short-circuit protection
When the end of the AC output shorts out from inner or outer part directly or
indirectly, the inverter will cut off the AC output automatically .The inverter
will renew to put out .This function protects the inverter from breaking
