Inverter is a kind of DC to AC transformer, which is actually a kind of voltage inversion process with converter. The converter is to transform the AC voltage of the grid into a stable 12V DC output, while the inverter is to transform the 12V DC voltage output from the Adapter into a high-frequency high-voltage AC; both parts also use the pulse width modulation (PWM) technology that is used more often. The core part is a PWM integrated controller, the Adapter is UC3842, the inverter is used TL5001 chip. TL5001 operating voltage range of 3.6 ~ 40V, its internal set an error amplifier, a regulator, oscillator, deadband control PWM generator, low voltage protection circuit and short circuit protection circuit and so on.
An inverter is a device that converts DC power (batteries, accumulators) into AC power (generally 220v50HZ sine or square wave). In layman‘s terms, an inverter is a device that converts direct current (DC) to alternating current (AC). It consists of an inverter bridge, control logic and a filter circuit.
Simply put, an inverter is an electronic device that converts low-voltage (12 or 24 or 48 volts) DC to 220 volts AC. The inverter is so named because it usually rectifies 220 volts AC to DC for use, while the inverter does the opposite. In a "mobile" era, mobile office, mobile communication, mobile leisure and entertainment. In this mobile state, not only do you need the low voltage DC power supplied by batteries or batteries, but you also need the 220V AC power that is indispensable in your daily environment, and an inverter can meet the demand.
Working Characteristics
1.High conversion efficiency and fast start-up;
2.Good safety performance: the product is equipped with 5 kinds of protection functions: short circuit, overload, over/under voltage, over temperature;
3.Good physical properties: the product adopts all-aluminium shell, good heat dissipation performance, the surface of the hard oxidation treatment, good friction resistance, and can resist a certain degree of extrusion or impact of external forces;
4.Strong adaptability and stability with load.
Working efficiency
The inverter itself consumes part of the power when working, so its input power should be greater than its output power. The efficiency of the inverter is the ratio of the output power of the inverter to the input power, i.e. the efficiency of the inverter is the ratio of the output power to the input power. If an inverter inputs 100 watts of DC power and outputs 90 watts of AC power, then its efficiency is 90%.
Scope of use.
1.Use office equipment (e.g., computers, fax machines, printers, scanners, etc.);
2.Use of life appliances (e.g., game consoles, DVDs, stereos, video cameras, electric fans, lighting fixtures, etc.);
3.Or when you need to charge batteries (batteries for mobile phones, electric shavers, digital cameras, camcorders, etc.);
4.should be placed in a ventilated, dry place, beware of rain, and with the surrounding objects have a distance of 20cm or more, away from flammable and explosive products, do not place or cover other items on the machine, the use of the ambient temperature is not greater than 40 ℃.
5. charging and inverter can not be carried out at the same time. That is, the charging plug should not be inserted into the electrical circuit of the inverter output when inverting.
6. The interval between two switch-on times is not less than 5 seconds (cut off the input power).
7. please use a dry cloth or anti-static cloth to wipe to keep the machine clean.
8.before connecting the input and output of the machine, please firstly ground the shell of the machine correctly.
9. in order to avoid accidents, users are strictly prohibited to open the chassis for operation and use.
10. suspect that the machine has a fault, please do not continue to operate and use, should cut off the input and output in a timely manner, by qualified maintenance personnel or maintenance units to check and repair.
11. when connecting the battery, make sure that there is no other metal objects on your hands, so as to avoid short-circuiting the battery and burning 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: can not be immersed in water or rain;
(2) Cool: temperature between 0℃ and 40℃;
(3) Ventilation: keep no foreign matter within 5CM on the shell, and other end faces are well ventilated.
13Method of installation and use
(1)Place the converter switch in the OFF position, then insert the cigar tip into the cigarette lighter socket in the car, make sure it is inserted in place but with good contact;
(2) Confirm that the power of all electrical appliances is below the nominal power of G-ICE before use, insert the 220V plug of the electrical appliances directly into the 220V socket at one end of the converter, and make sure that the sum of the power of all connected electrical appliances of the two sockets is within the nominal power of G-ICE;
(3)Switch on the converter, the green indicator light is on, indicating normal operation;
(4) The red indicator light is on, indicating that the converter is switched off due to overvoltage/undervoltage/overload/overtemperature;
(5) In many cases, due to the limited output of the vehicle cigarette lighter socket, the converter alarms or shuts down during normal use, which can be restored to normal by starting the vehicle or reducing the power consumption.
