Jamaica the switching frequency of the AC-DC switching power supply module?(1)

Ring current backup
The ring current generator is mainly used in the telephone exchange exchange to provide ringing to the telephone users, and is generally used in a biased state. Bias can be divided into positive bias and negative bias. In order to improve the reliability of the ring current system, the ring current needs to be backed up. Installation and maintenance of module power supply
Since the types, series and specifications of the modular power supplies produced by various companies are difficult to count, their functional characteristics and physical characteristics are not the same, so they are also different in installation, use and maintenance, but the following aspects should be paid attention to

What is the operating frequency of Jamaica the AC-DC switching 48V input power supply module? What factors need to be considered when choosing an AC-DC switching 48V input power supply module? Are these questions the focus of your circuit design? The following are several elements for selecting the operating frequency.

Jamaica Choosing the switching frequency of the 48V input power supply does not mean choosing the switching frequency of the 48V input power supply with a good switching frequency, but the choice is suitable for your own use. Most of the current market is like this. The frequency of the AC-DC switching 48V input power supply module is between 50K and 135K, and this frequency range can meet most applications. Let's discuss it. Some of the problems that AC-DC encounters when choosing switching frequency:
