W-330 Modified Sine Wave Inverter

Modified Sine Wave Solar Inverter W-330, CE approved, good quality favorable price Specilizing in solar system. Inverters are able to transfer 12V or 24V DC to 220VAC for domestic appliances.

Protective functions:

1.      Overloading protection

2.      Short circuit protection

3.      Reversed polarity protection

4.      Thermic protection

The inverter JUTAW-330 can transform the electrical energy of 12V direct current into the energy of 230V alternating current that can be used in appliances, such as computer, TV, acoustics, fax machine, haircut appliances, etc.

The inverter JUTA W-330 is attached a lighting bulb and the indication of cell voltage and also possesses of other functions, for instance, overload protection, exceeding temperature protection and so on.

Operation procedure of bootstrap:

1.        Turn the switch on-off of the inverter to the OFF;

2.        Make the red string nip the positive pole + and the black string nip the negative pole - of the inverter. (Connection must be correct.)

3.        Insert the outlets of your appliances into the suitable sockets on the front of the inverter (Note: The total nominal power of your appliances mustnt overrun the power of the inverter);

4.        Turn on the inverter. The green indicator lamp on the inverter gets light, which shows theres alternating voltage exporting. Then the appliances can start to work.

 

Operation procedure of turning off:

Turn the switch on-off of inverter to the OFF, (If only turn off the appliances and havent turned off the inverter, it would waste the energy about 3.5W).

The indication of the cell voltage:

After the read string (+) and the black string (--) nip correctly the poles, the indicator lamps of the cell voltage will light. There are three indicator lamps totally. Two indicator lamps lighting means the voltage is up to snuff; Three indicator lamps lighting means the voltage is enough; And only one indicator lamp lighting means the voltage is too low, and suggest to use it after charging.

The functions of protection:

1.  Overloading protection:  When insert too many appliances and the total power loads, the inverter will stop working within ten seconds. Then the red indicator lamp will get light and the inverter will be fixed on the protection state. Until reduce the load, turn the on-off of the power to the OFF over ten seconds and turn the on-off to the ON, then the inverter will renew to work;

2.  Exceeding temperature protection: When the load is too much or the climate is fervent or the ventilation is bad, the interior temperature of the inverter will get higher. When the temperature rises to some extent, the red indicator lamp will get light and the inverter will stop working and be fixed on the protection state. Suggest to reduce the load or to improve the ventilation condition. After the interior temperature gets low, turn the switch of on-off to the OFF over ten seconds and turn it back to the ON, then the inverter will renew to work.

NOTE:

1.        The inverter is suitable to be put near the battery. Dont lengthen the wires of two string nips.

2.        The red string nips the positive pole + and the black red nips the negative pole -. If the strings are nipped by mistake, the inverter may be damaged.

3.        The inverter should be put under the good ventilation.

4.   The fan-out can not be short-circuited in order to prevent the inverter from being damaged.
