New to buy the switching power supply, it should be bought fake, and after the output with the amount of output DC24V, then a small motor to 23.7, and a parallel down to 23.5, and on the 23V, and help me analyze Cause, change any solution
This step by step, look at the power output power is not lower than the rated power of the motor, did not continue
Your power supply is not a long output line, no continuation
Appropriate increase the load of the motor to see if the power can work, you can continue
Long time to work for a period of time to see, no problem, that power no problem
Voltage drop a little, if there is no impact on the normal use is acceptable, if the transformer down more powerful
This switching power supply does not provide the power you want. The The Best for one. The The
The regulator is too bad.
There is a pressure drop is normal, of course, the better the better the pressure drop, no pressure drop is not possible. Can only change, no way to improve
General switching power supply under normal load voltage change ± 5/00 below, beyond the more, it is not normal. You should check whether the load is too large, the power capacity is sufficient, the power supply internal feedback loop is normal.
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.
This is normal.
Switching power supply is also a power supply, there is resistance, the power output voltage can be expressed by the following formula:
Uo = E-r × Io, where Uo is the output voltage, E is the electromotive force of the power supply, r is the internal resistance of the power supply, Io is the output current. R and Io of the product for the power consumption, do not work. E for a power supply, the basic is custom, equal to no-load voltage, also known as open circuit voltage.
Through the formula can be tested, the output voltage of the power supply and output current is closely related to the larger output current, the lower the output voltage.
The internal resistance of the power supply r is related to a variety of factors, including power tube, transformer, circuit, etc., different power voltage, the internal resistance r is very large difference is the main factor of power fever, r value is smaller, the higher the power efficiency , The more stable the output voltage. The use of smaller internal resistance transformer, power greater power tube, optimized circuit design can effectively reduce the power supply resistance.
