Q:Inverter problem
(0 ~ 20mA), but the main input / output is completely isolated, than the output of the inverter simulation of the output of the analog output The amount of signal impact resistance, anti-interference ability.
Q:Laptop power adapter is used to do what
The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.
Q:Who knows how the frequency converter works
Rectifier circuit The function of the rectifier circuit is to convert the AC power into a DC power supply. Rectifier circuit is generally a separate rectifier module.
Q:What are the types of power adapter used in notebooks?
Notebook function is limited, such as power requirements of only 50-70 watts (W). In recent years, power requirements have risen above 100 W, but the expectations for weight and size have not improved accordingly. In addition, the need to meet the low standby power performance in the specification, external power (EPS) efficiency requirements and IEC1000-3-2 harmonic power requirements above 75 W make this challenge more difficult to deal with. This article explores new trends that enable power supply manufacturers to address these challenges and provide alternative solutions to choose from.
Q:Does the inverter set the number of poles to match the number of poles of the motor?
Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on.
Q:How to view your own laptop power adapter is how much tile?
1, the power adapter has a logo, you can find their own look, close to the paper or direct letterpress printed with the voltage, current and power. If there is no write power, the direct voltage multiplied by the current is the maximum power. 2, if the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we formula W (power) = V (voltage) xI (current) to calculate. Calculate the formula with a power to know the output power is 20 × 4.5 = 90W.
Q:Why the number of motor poles increased, the inverter capacity will increase
The number of poles of the motor is not directly related to the rated current, but the number of poles is larger and the power factor is lower and the rated current will be higher.
Q:Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,
It should be the inverter problem, I have encountered before, followed by the inverter upgrade was resolved. Is to replace a set of power board, power board, CPU board.
Q:Can the laptop's power adapter be used for years?
In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, which is the so-called "travel power adapter", if the city voltage to only 110V country , This feature is very useful, and some parallel notebook computers are sold only in the origin, there is no such compatible voltage design, or even only a single 110V input voltage, in our 220V mains voltage will be burned to burn.
Q:The laptop power adapter is burned
You this situation or the first adapter to try, it is likely that the adapter power shortage. If you change the adapter or so, then your problem is big, there may be your laptop to protect the isolation circuit and the charging circuit is a problem, in the insurance repair is free, if the insurance, and to be afraid of a little fear Small expensive, the adapter to buy a cottage on the line, as long as tens of dollars.
