Remarks 1) Measurement of ripple and noise: Usina a 12 "twisted-pair line with a capacitor of 0.1uF and 47uF in parallel at the terminal,the measurement is carried out at 20MHz bandwidth.(2)Efficiency is tested at the input voltage of 230VAC, rated load and 25ºC ambient temperature.Accuracy: including setting error,Linear adjustment rate and load adjustment rate.Test method of linear adjustment rate: testing from low voltage to high voltage at rated load Load adiustment rate test method: from 0%-100% rated load.The start-up time is measured in the cold start state. and the fast frequent switch machine may increase the startup time.When the altitude is above 2000 meters, the operating temperature should be lowered by 5/1000.

What is C&J Switching Power Supply?

A C&J switching power supply is a power supply that converts alternating current to direct current. Widely used in various electronic devices, such as computers, TVs, mobile phones, etc. Compared with traditional power supplies, C&J switching power supplies have significant advantages. First, it's more efficient, uses less energy and generates less heat. This makes it ideal for devices that need to run for extended periods of time without overheating. Another advantage of C&J switching power supplies is their small size and light weight. Traditional power supplies require large transformers and capacitors, which take up a lot of space and add unnecessary weight. With C&J switching power supplies, these bulky components can be eliminated, resulting in smaller and lighter power supplies. C&J switching power supplies also offer greater flexibility. It can work in a wider input voltage and frequency range, making it suitable for different countries and regions with different power supply standards. It also provides better output voltage regulation, reducing the risk of system failure due to input voltage fluctuations. Finally, C&J switching power supply is more cost-effective. While it may cost more initially, it saves energy and reduces maintenance costs in the long run. Its higher efficiency means less energy is wasted, resulting in lower electricity bill costs. Its smaller size and lighter weight also mean lower shipping and handling costs. In summary, C&J switching power supplies are a powerful and efficient alternative to conventional power supplies. Its many advantages make it ideal for use in a wide variety of electronic devices, from small mobile devices to large computer systems. Its efficiency, small size, flexibility and cost-effectiveness make it a popular choice in today's electronics market.
