Inverter use attention
1, DC voltage should be consistent
Each inverter has a DC voltage value, such as 12V, 24V, etc.
The inverter requires that the battery voltage must be the same as the inverter DC input voltage. For example, a 12V inverter must have a 12V battery.
2. The output power of the inverter must be greater than the power used by the appliance. Especially for appliances with large power at startup, such as refrigerators and air conditioners, it is necessary to leave a larger margin.
3, the positive and negative poles must be connected correctly
The DC voltage to which the inverter is connected is marked with a positive and negative pole. Red is positive (+), black is negative (-), battery is also marked with positive and negative, red is positive (+), black is negative (-), must be positive (red) when connected, negative Negative (black to black). The cable diameter must be thick enough and the length of the cable should be as small as possible.
4, should be placed in a ventilated, dry place, beware of rain, and the surrounding objects have a distance of more than 20cm, away from easy
Burning explosives, do not place or cover other items on the machine, the ambient temperature is not more than 40 °C.
5, charging and inverter can not be carried out at the same time. That is, the charging plug cannot be inserted into the electrical circuit of the inverter output during inverter.
6. The interval between two starts is not less than 5 seconds (disconnect the input power).
7. Wipe with a dry cloth or an antistatic cloth to keep the machine clean.
8. Before connecting the input and output of the machine, first ground the casing of the machine correctly.
9. To avoid accidents, users are forbidden to open the case for operation and use.
10. If you suspect that the machine is faulty, please do not continue to operate and use it.
The inverter (Fig. 5) should cut off the input and output in time, and be inspected and repaired by qualified maintenance personnel or maintenance units.
11. When connecting the battery, make sure there are no other metal objects on the hand to avoid short circuit of the battery and burn the human body.
12, the use of the environment, based on safety and performance considerations, the installation environment should have the following conditions:
1) Dry: Do not soak or rain;
2) cool: temperature between 0 ° C and 40 ° C;
3) Ventilation: Keep no foreign matter in the 5CM on the casing, and the other end faces are well ventilated.
13, installation and use
1) Place the converter switch in the OFF position, then insert the cigar head into the cigarette lighter socket of the car to ensure that it is in place and in good contact;
2) Confirm that the power of all appliances is below the nominal G-ICE power. Insert the 220V plug of the appliance directly into the 220V socket on one end of the converter, and ensure that the sum of the power of all connected appliances in the two sockets is in G-ICE. Within the nominal power;
3) Turn on the converter switch, the green indicator light is on, indicating that the operation is normal.
4) The red indicator light is on, indicating that the converter is turned off due to overvoltage/undervoltage/overload/overtemperature.
5) In many cases, because the output of the cigarette lighter socket is limited, the converter will alarm or turn off during normal use. At this time, as long as the vehicle is started or the power consumption is reduced, it can be restored.
14, matters needing attention
1) The power of the TV, monitor, motor, etc. peaks at startup.
Inverter (Figure 6) Although the converter can withstand 2 times the peak power of the nominal power, some of the peak power of the power-compliant appliance may exceed the peak output power of the converter, causing overload protection and the current is turned off. At the same time, it is possible to drive a plurality of electrical appliances. In this case, the electrical switch should be turned off, the converter switch should be turned on, and then the electrical switch should be turned on one by one, and the highest peak electrical appliance should be turned on first.
2) During use, the battery voltage begins to drop. When the voltage at the DC input of the converter drops to 10.4-11V, the alarm sounds, and the computer or other sensitive appliances should be turned off in time. If the alarm sound is ignored, the conversion The device will automatically turn off when the voltage reaches 9.7-10.3V, which can prevent the battery from being over-discharged. After the power protection is turned off, the red indicator light will be on;
3) The vehicle should be started in time to charge the battery to prevent power failure, affecting the start of the car and the battery life;
4) Although the converter has no overvoltage protection function and the input voltage exceeds 16V, it may damage the converter;
5) After continuous use, the surface temperature of the casing will rise to 60 °C, pay attention to the smooth flow of air, and objects that are susceptible to high temperature should be kept away.
