- Q:What is the meaning of the magnetic ring color in the switching power supply?
- Magnetic ring color
Magnetic ring are black A,
Up to that is deep black, bright black this difference
But the difference is not strict,
Or button-type magnetic ring with a shell, sub-white black, gray
We are doing this
- Q:What is the basic principle of switching power supply?
- So as to achieve automatic adjustment of the high-frequency pulse voltage duty cycle to achieve the final output DC voltage stability. Adjust the output DC voltage principle is the same, with artificial methods to change the oscillation frequency and pulse duty to achieve the purpose of changing the output DC voltage. Simply put the basic principle of switching power supply is: AC variable DC variable pulse voltage and then change the process of a DC. It has a high precision regulator, small consumption and other characteristics.
- Q:Will a 12V10A switching power supply with a few 12V2A surveillance camera?
- Power power: 12X10 = 120W;
Monitor the camera power: 12X2 = 24W;
Current point of view: 10A divided by 2A = 5;
Power point of view: 120W divided by 24W = 5;
So you can install five (the same voltage, the current and power which is less, with that standard).
- Q:How to transform the switching power supply, the original AC 220 input into DC 84-100 input output unchanged
- It is difficult to change, you can consider the use of ready-made DC-DC converter
- Q:What is the linearity of switching power supply
- Different power supply, linear adjustment rate is different
Constant pressure source:
Linear adjustment rate: the rate of change of the output voltage within the specified input voltage range; ΔV / V = (V - V1) / V * 100%
Load rate: change in load within the specified range, change rate of output voltage; ΔV / V = (V-V1) / V * 100%
A constant current source:
Linear adjustment rate: the rate of change of the output current within the specified input voltage range; ΔI / I = (I - I1) / I * 100%
Load regulation: change in load within the specified range, change rate of output current; ΔI / I = (I-I1) / I * 100%
- Q:What is the difference between Switch Mode Power Supply and electronic switch? Where are they?
- To the electronic switch to open a signal, the line connected, disconnect the control signal or to a shutdown signal, the electronic switch off. The electronic switch differs from the normal switch in that it is non-contact. So to avoid such as manual switch button and contactor lights in the opening and breaking when the spark loss and mechanical noise. And control the power of small control easy. Switching devices in the switching power supply, such as MOS tube and IGBT are all electronic switches, SCR also belong to the electronic switch. And we usually mention the electronic switch is the market of solid-state relays, etc., it is also the principle of the use of thyristor.
- 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:Switching power supply fan does not turn, it was encountered this problem?
- Three words, that is, automatic temperature control, to the temperature to a certain extent will turn
- Q:Switching power supply COM how to connect
- Originally is the ground ah, but the output of the ground is the output voltage is not the input of the ground can not be wrong ah multi-channel output power is some public
- Q:High frequency switching power supply is what the meaning of high frequency, what is the specific meaning?
- High-frequency switching power supply of strong penetration, good adhesion, can effectively improve the deposition rate of the coating; flexible use, simple operation; protection function is complete;
