Do you know the difference between a power adapter and a charger? Before introducing the difference between today's charger and power adapter, we must first understand what a charger is and what is a power adapter. The power adapter refers to the power supply for the device, such as the power supply... read more
1.Difference between variable frequency power supply and power supply – Purpose Frequency conversion power supply by changing the output power voltage and frequency, and provide a pure stable power supply, for the use of the load, and the frequency converter is by changing the frequency and voltage,... read more
UL power cord plug: 120V 50/60Hz divided into two core wire, three core wire and polar, non-polar, the United States of America power supply plug copper sheet must have a rubber cover;Two - core printed wire represents the wire;The big polarity pin is zero line, the small pin is fire line (power lin... read more
1. Low power consumption and high efficiency. In the switching power supply circuit, under the excitation of the excitation signal, the transistor V works alternately in the on-off and off-on switching states. The switching speed is very fast, and the frequency is generally about 50kHz. In some tech... read more
Switching power supply is a power supply is widely used in recent years, it has small volume, light weight, low energy consumption and convenient use, widely used in all kinds of electronic products. But as a result of switching power supply control circuit is more complex, the output ripple voltage... read more
