What is The Power Inverter (2)?
Updated: 2013-12-10 01:34:21 (GOBRIGHT NEWS DEPT)
5. What is the efficiency of the inverter?
The inverter will consume a part of its own power at work. Therefore, its input power is greater than its output power. The efficiency of the inverter is the inverter input power and output power ratio. For example if a power inverter input 100W DC output 90w AC, its efficiency is 90%.
6. What is a continuous output power? What is the peak output power?
Some electric appliances use electromotor, such as refrigerators, washing machines, electric drills, etc, their starting moment need a great current to promote the electromotor. Once the electromotor was promoted successfully, they only need small current maintain its normal operation.
Therefore, the inverter has continuous output power and peak output power. Continuous output power is rated output power; generally, peak output power of 2 times the rated output power. What are more, some electrical appliances, such as air conditioning, refrigerator, and its starting current of 3-7 times the normal operating current. Therefore, the inverter can work normally only when it can meet the peak power of the electrical appliances starting moment.
7. How to connect with the power inverter and load?
The 150W inverter plug can be directly put into the cigarette lighter plug if the electrical appliances under 150W. More than 150W inverter, it can be connect to the battery by the alligator clip. The red wire is attached to the anode, the black wire is attached to the cathode (remember; make sure the wire was connected in right way).
If the using electricity location is far from the battery, the principles of the inverter connection is that the connecting wire of the inverter and battery should be as short as possible, while the output of 220V AC wire can be longer.
8. How many power does the Car cigarette lighter socket output?
Inverter can carry 100W electrical appliances from the cigarette lighter socket. However, according to the customer's feedback, inverter can alarm automatically when it connect P4 notebook a few minutes later. As we know, P4 notebook power consumption is higher about 90W. Due to some Vehicle Type use the wires and cigarette lighter socket cannot meet the requirement. When the current become larger and the wear and tear increased so that the inverter voltage decline to the under-voltage protection critical point 10 V, resulting in the inverter cannot supply the electricity. To solve this problem and ensure the use of the inverter normal, safe, reliable, we proposed that user choose 2.5mm2 high-quality copper wires or replace the cigarette lighter if necessary.
9. If the power inverter can use when close the automobile engine?
Yes, When use 350W low-power electrical appliances, the automobile battery can provide 30-60 minutes power if shut down the engine. When use a 50-60W notebook, the use of time will be longer. Our quasi-sine wave inverter has under-voltage warning and under-voltage protection circuit. The voltage drops to 10V when the battery was used for a long time. The under voltage protection circuit start up and output voltage cut off and alarm automatically .In this way, It can prevent the starting engine accident when the voltage is too low. Therefore, the inverter can be used safely when the engine shut down.
