An AC power supply is responsible for providing AC power to the load. The power input can be either AC or DC. You need an AC power supply because the power from the wall outlet does not meet the specifications of the load. In order for the load to operate properly, you need to transform the AC power supply to tune the AC power from the supply to the voltage, current, and frequency required by the device. This can be accomplished by raising or lowering the voltage and then filtering the signal.
You can use an AC power supply for testing. The AC power supply can emulate grid outages, harmonics, surges, or other events that may cause the device under test (DUT) to fail.
There are several ways to test a DC power supply, here we only introduce a few common methods. Conductivity test: You can use the multimeter's conductivity mode to accomplish this test. Touch the positive and negative terminals of the power supply with the multimeter pen. If it is on, the multimeter will beep. This test is designed to determine if the power supply is delivering power and if there are any breaks in the wiring. Voltage...
View Full VersionWhat does the frequency of electricity mean? Here are the basics of frequency, regionality, and measurement Since electricity and voltage are invisible things, many people will think they are elusive. But in fact, they are only invisible, and it is not difficult to understand them. Below, we will introduce the frequency basis of electricity and voltage in an easy-to-understand way, regional differences in frequency, and how...
View Full VersionWondering about resistance measurement methods! In this article, we will cover basic resistance measurements and precautions. Resistance is very important in electronic device circuits. If the resistance is not appropriate, it can lead to malfunctions and other problems. However, electricity is not visible. To find out if the resistance in a circuit is appropriate, you need to use a specialized measuring instrument. To measure resistance, you need to use a measuring instrument...
View Full VersionHow to measure frequency? Measurable Devices, Measurement Methods, and Precautions In everyday life, many people say they don't know much about the frequencies of electrical appliances. However, some electrical appliances have specific compatible frequencies, and using electricity at a frequency that is not compatible with the product may lead to malfunctions, fires, and other risks. In addition, in industrial equipment, there are electrical designed to operate at fixed or variable frequencies...
