- Q:Switching power supply start-up time, hold time, long time, fall time, which standard
- Start time: that is, since the input power input to the output voltage reaches 90% of the specification time, from the boot to the machine to work
- Q:What brand of switching power supply cost-effective?
- See what kind of switching power supply, LED, or industrial use, or communication.
- Q:What is the difference between DC regulated switching power supply and linear power supply?
- Switching power supply: high efficiency, small size, inertial components (inductance and smooth capacitance, etc.);
Traditional power supply in turn is it, but the traditional power of the biggest advantage is the small noise, harmonic interference is small.
- Q:12V switching power supply measurement 13.7V normal?
- Adjust it to 12V, the terminal next to the adjustment potentiometer
- Q:Is the DC input and AC input switching power supply available?
- General low-power switching power supply input can be as low as 85VAC. Equivalent to 110DC, in the allowable voltage range should be possible.
- Q:Switching power supply isolated design, what is the meaning of isolation?
- Switching Power Supply The dual isolation design means that the transformers inside the power supply are electrically incompatible (they are magnetically coupled, the primary windings and the two secondary windings are not connected to each other), and the corresponding external and electrical paths are also Unrelated, both outputs are not common
- Q:The switching power supply has no output but the low side indicator flashes
- 3842 6 feet is the chip output pin, if burned there, it is likely that the chip and switch are broken
But the power output there is voltage, although unstable, indicating that the chip and switch is still working.
You can test the chip 7 feet voltage is stable, if the stability of the power supply is likely to have problems on the low side.
Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply generally by the pulse width modulation (PWM) control IC and MOSFET composition. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating. At present, the switching power supply to small, lightweight and efficient features are widely used almost all of the electronic equipment, electronic information industry is the rapid development of an indispensable power supply.
Indicator light: There is always a light on a key switch for a home lighting. This indicator light is extremely large, so that the circuit current is minimal, so that the voltage in the night with the electrical voltage can not reach the rated voltage can not be bright, under normal circumstances this indicator has a capacitor, because a small The indicator light can not accommodate the voltage of 220v.
- Q:What is a linear adapter and a switching power adapter
- Ordinary through the frequency transformer re-finishing filter series adjustment regulator (such as integrated chip 78XX) is a linear adapter; use of switching power supply called switching power adapter.
- Q:Working principle of small switching power supply
- Small switching power supply works is to control the switching transistor through and turn off the time ratio, to maintain a stable output voltage of a power supply, switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. Switching power and linear power compared to the cost of both the output power increases with the growth, but the growth rate of the two different. Linear power costs at an output power point, but higher than the switching power supply, which is called the cost of reversal point.
- Q:Switching power supply transformer core how to choose?
- 1, according to the power to select the core size, combined with the layout of the whole board to select the core shape, according to environmental factors, switching frequency selection core material, according to the feasibility of core procurement, raw material costs to choose, consider the transformer processing technology Requirements, select the skeleton core shape, the output power of the size of the core material is mainly to see the size of the cross-sectional area of the core, the number of windings and the number of windings and so the main look at the size of the window area of the core material, in fact, Its best application. That is, when you choose to use, Yang long, to avoid its short, so that better design, select the core material, the first to determine the basic parameters of its core material, that is, according to your specific use Environment to choose whether the PC40 or PC50;
We have various advanced equipment, such as wave soldering and reflow soldering machine, RoHS testing, environmental testing system, etc. Only top international brand components are adopted for our key parts to ensure long lifetime and high reliability. Each unit is given full load burn-in test.
