Q:What is the linearity of switching power supply
Linear adjustment rate for the input voltage maximum and minimum output voltage stability indicators, but this provision has a number of standards to 220V, for example, if you specify a maximum of 264, the minimum is 185V, Vof said full load when the output voltage, there are three algorithms : The algorithm is as follows:     ATE which in the end with which one, you will test the report out to count about. I used to use the CHROMA6000, which is the formula inside the dead, but CHROMA8000 as if you can modify their own. For only a set of outputs, there is a LOAD REGULATION is the load regulation rate, Von said no load when the output voltage, the algorithm is as follows:      Respectively, called the normal voltage load regulation, high pressure load regulation, low voltage load regulation. When there are multiple sets of output, one or more of the output with overloaded but no load output increases due to the increase in duty cycle, relative to the original increase in the number of cross-load regulation is called Accuracy range, because each group must be set at least once overload or light load to observe the other output of the situation, so called cross adjustment.
Q:Switching power supply and communication power difference
Switching power supply is a high-frequency oscillating electronic circuit for voltage conversion. The main contents are: step-up or buck, direct current conversion to alternating current, or alternating current to direct current.
Q:Note the operating conditions of 220V voltage and the order of switching power supply
220v are low-voltage circuit, there is no provision, as long as the attention of several points: 1, do not touch the live part directly. 2, if you want to live work, you must ensure that the human body and the earth insulation (standing on the bench or insulation pad). Can not touch FireWire and Neutral Line at the same time. 3, the normal operation of the order: to use the switch off the circuit, first pull the sub-gate and then pull the total gate, the first joint gate and then sub-gate. Line maintenance sequence: Power off - pull the security ground - proof signs pull off the line - operation - review the operation is correct to complete the task - remove the insurance ground - remove the warning card pull off the line - power
Q:Switching power supply (AC-DC) use notes and tips
  Fourth, in order to achieve full heat effect, generally installed in the air convection conditions good position or installed in the chassis shell through the shell will heat out.   5, LED switching power supply factory before the addition of resistive load, if used in capacitive or emotional load, should be preceded by the order to explain   Sixth, for the dual output symmetrical load, the preferred use of symmetrical output power   Seven, the power supply FG ungrounded users, hand touch the shell or the output of Ma electrical feeling is a normal phenomenon, floating when the FG on the earth about 110V AC output, which is the power of the internal structure of the decision.
Q:Switching power supply carrying capacity how to test ??
Some set 1.2 times, 1.5 times, there are 2 times. The reason is to prevent the instantaneous impact of the current so that the power supply malfunction.
Q:Switching power supply, constant current power supply, resistance to the power supply where the benefits?
Roughly compare it Switching power supply, RC power supply ----- these two, the general switching power supply to do greater power; resistance capacity of the power is generally micro power Constant current power supply and the above species is not compared, the switching power supply can also be done
Q:Is switching power and transformer the same thing?
Switching power supply is used to control the switch through the circuit for high-speed pass and cut off. The conversion of direct current into high-frequency alternating current is provided to the transformer for voltage change to produce the required group or groups of voltages. The transformer is voltage-converted by magnetic coupling. The switching power supply is in a field and can not be used instead of the transformer. Output without transformer, rectifier, filter, regulator way pure.
Q:The main function of the communication switching power supply is
Do not know the exact meaning of your problem. We usually talk about the communication with the switching power supply is rated at 48V DC power supply. Power in any circuit, of course, is to its power supply, like a telephone, the phone's two lines are rated at 48V DC, no load up to 60V. Communication also through the send, receive, and intermediate processing process, the processing of the chip ah these are also need to supply the thiophene.
Q:Switching power supply isolated design, what is the meaning of isolation?
Isolation is achieved through the transformer, in the design of switching power supply when the use of isolation transformers (primary winding and secondary winding is not connected), so that the output of the power supply and the input power is not common, dual isolation is the switching power supply of two Road output are not common. The advantage of isolation is that the primary side of the transformer or the side of the circuit when there is a short circuit will not burn the other side of the components.
Q:Why switching power supply with two series capacitor filter, with a can you
Two series to increase the pressure, improve the reliability of the power supply.
