Q:DC power supply technical indicators which
DC power supply specifications can be divided into two categories: one is the characteristics of indicators, reflecting the inherent characteristics of DC power supply, such as input voltage, output voltage, output current, output voltage adjustment range; the other is the quality indicators , Reflecting the advantages and disadvantages of DC power supply, including stability, equivalent resistance (output resistance), ripple voltage and temperature coefficient. 1, the characteristic index (1) output voltage range In line with the DC power supply operating conditions, the normal working output voltage range. The upper limit of this indicator is determined by the maximum input voltage and the minimum input-to-output voltage difference, and its lower limit is determined by the reference voltage inside the DC regulated power supply. (2) Maximum input - output voltage difference This indicator characterizes the voltage difference between the maximum input and output allowed under the normal operating conditions of the DC regulated power supply. The value depends mainly on the voltage regulation of the DC regulated power supply. (3) minimum input - output voltage difference This indicator characterizes the voltage difference between the minimum input and output required to ensure proper operation of the DC power supply. (4) Output load current range The output load current range, also known as the output current range, in this current range, the DC power supply should be able to ensure compliance with the indicators given by the indicators.
Q:Adjustable DC regulated power supply works
The working principle, application and prospect of the voltage source. First, the working principle of DC power supply DC power supply is a 220V frequency AC power conversion voltage regulator output voltage of the device, it needs to go through the transformer, rectifier, filter, regulator four links to complete. The working principle of the four links is as follows: (1) Power transformer: is a step-down transformer, it will convert 220V AC voltage to meet the required AC voltage, and sent to the rectifier circuit, the transformer by the secondary side of the transformer voltage The (2) rectifier filter circuit: rectifier circuit converts the AC voltage Ui into pulsating DC voltage. And then filter the filter circuit to filter out the larger ripple components, the output ripple smaller DC voltage U1. Commonly used rectifier filter circuit with full-wave rectifier filter, bridge rectifier filter.
Q:Home voltage instability, is a good regulator, or with a stable power supply?
Only AC voltage regulator, if this is not, buy a UPS, open the computer when the inverter, do not open the time, the battery charge.
Q:DC power supply CH1.CH2 two channels with wire connection and not connected What is the difference
And then from the negative electrode of CH1 and the positive electrode of CH2 (presumably, the detailed need to look at the Intel Rotter IPD-3305SLU instructions) leads to a line connected to your load on the line. Do not need to do their own in the output and in series connection operation.
Q:What is the difference between variable frequency power supply and regulated power supply?
Frequency conversion power supply is mainly adjustable frequency regulator frequency, frequency: 40-499.9HZ any adjustable, adjustable voltage: phase voltage 0-300V arbitrary adjustable, frequency accuracy: 0.1%, regulation accuracy: 0.3%, frequency Power supply can replace the regulator, and more than the regulator is much better, but the price should be very expensive. Frequency conversion power supply is the laboratory, the product of the high demand for testing the ideal power supply.
Q:Why Capacitor Filtering in DC Regulated Power Supply
Large capacity capacitor or energy storage components! Can improve the power of the power load performance! The same can also short-circuit return residual high frequency And AC signal!
Q:Power supply KA7805 how to judge good or bad
KA7805 a total of 3 pins, the input pin plus 9V voltage, measuring the output pin is 5V. Ground pin shared.
Q:Is the regulator the same as the role of UPS? What's the difference?
If you have a budget in the power of 1,000 yuan, then you can buy a domestic 1KVA online UPS, the basic solution to your current problems. If you feel that spend a little more money, then advise you to buy a servo-type regulator.
Q:Electrical Engineering! Why can not directly use a multimeter to measure the power supply of the exchange of ripple?
In general, multimeter AC can only measure the pure AC voltage. The output voltage of the regulated power supply is equivalent to the DC voltage + ripple voltage, and the multimeter exchange file can not be measured normally In addition, the ripple voltage is not necessarily a sine wave voltage, the regulated power supply itself or by external interference will produce complex ripple voltage, and the general multimeter AC voltage file is measured the average AC voltage. The ripple voltage is not a pure sine wave when the multimeter can not be accurately measured From the other side, the general linear power supply can only guarantee the output voltage in the lower frequency range of stability, and for more than tens of kHz ripple rejection is very limited. That is ripple voltage frequency is generally high, may have exceeded the multimeter AC file frequency response range, this time the multimeter is still unable to correctly measure
Q:Is the switching power supply output from a regulated or pulsed power supply?
This is hard to say, switching power supply is very wide, can be DC power (regulator or steady flow) and pulse power, depending on the specific load demand. Better mobile phone charger is the output of the pulse, which is conducive to the battery life, the output of the DC also. On the phone battery charging is still more complex, not the general regulator or steady flow power can be completed, to use a dedicated chip. Regulator and steady flow operation should also be changed according to the charging process. Please refer to the relevant literature.
