Q:LM317 to do 0-24V adjustable DC power supply 80
LM317 voltage output range is 1.25V ~ 37V, 1.25V below can not guarantee. Circuit diagram is as follows, the voltage calculation formula Iadj is very small (50μA) can be ignored, the potentiometer resistance selection 4.7kΩ can meet the output voltage 1.25V ~ 24V adjustment range.
Q:From the old computer to remove a switch power supply can do what, can be used when the power? how to use?
Yes, the main power is enough power. Voltage and current are appropriate.
Q:How does the power supply protect all electrical appliances at home?
Hello there! You said the function requires two machines to complete: 1, the regulator: the external network input voltage is stable at the standard mains voltage of about 220V device. Installed in your home meter behind you can protect all the appliances. Power grid voltage is too high, beyond the upper limit of household appliances design, household appliances can not withstand the high voltage and the possibility of damage. The grid voltage is too low, the starting current of the electrical appliances will be low starting voltage, start the current is small and can not start normally, serious may make it long in the start of the high current state and damage the core components. 2, uninterruptible power supply (UPS): is to give your appliances to provide an uninterrupted power supply, such as power failure when your computer is not a power outage to eliminate the illegal shutdown caused by unnecessary losses. Due to power constraints, can not receive high-power appliances, in fact, no need to pick up other electrical appliances, only connected to the computer just fine.
Q:Adjustable DC regulated supply current is unstable
Your question did not make it clear that the load is the case of the current instability or how the matter. DC power supply is stable voltage, the current changes with the load changes, such as the load is the audio equipment, then the volume is large, the greater the current, so the current instability is normal.
Q:Why the output of DC power supply does not allow short circuit
It will burn it out. Regulator is to keep the voltage almost constant. Short circuit will have a lot of current generated, which has a lot of heat, the result is the power is broken.
Q:With the transformer why use DC power supply
We usually refer to the "DC power supply", is also available from the mains power supply, through the transformer buck, full bridge rectifier, filter, regulator, and so on several steps. But now the low-power power supply has been no use of transformer buck, but the direct use of PWM buck way buck. The advantage of this step-down is the small size and light weight. So our home TV, mobile phone charger, etc., has no traditional body of the transformer.
Q:Switching power supply and DC power supply difference
Switching power supply is through the switch on and off work, the output and input is not linear, the relationship is not obvious. DC power supply is a step-down linear power supply, the output and input into a linear.
Q:Is there a difference between a regulated power supply and a power adapter?
The first is the role of voltage regulator voltage is the second transformer power supply equipment
Q:How to control the DC regulated power supply output current constant?
Power supply can not do, you need is a constant current source.
Q:What is the difference between regulated power supplies and regulators?
The voltage of the power adapter in the case of no load is higher, if you pick up the load will find its voltage will come down, it is due to its own role is limited, just to provide a suitable voltage to the load , And the main role of the regulator is the regulator, it will be through its voltage stability in a certain range, more or less than this value it has action, the power adapter will not have this effect. These two can be distinguished according to the use of the situation, if it is in the load power requirements are not high places can be used with each other, but if the load on the power requirements are relatively high, even if the 1V voltage changes are not OK, then you must use the regulator , Otherwise do not burn the load also burn power.
We are committed to provide high quality products and services to meet diverse customer requirements and diverse market requirements. With the same diligent customer-oriented spirit, we are dedicated to continuously designing, manufacturing, marketing, and introducing our products to the diverse demanding power market.
