German There are three elements in the procurement of isolated module power supply(2)
Noise pollution has always been a major problem for manufacturers. In the early days, machinery and equipment would generate a lot of noise during work, which would affect the health of employees. According to the senior human resources department, it is very difficult to recruit workers at the moment. With the rise of Internet recruiting, it is easier for people to find jobs, but we are reluctant to work in production. If businesses cannot address noise pollution, they may not even find workers. After all, people these days take their health very seriously.
2. Insulation cannot be ignored.
high frequency switch
The rapid development of the communication industry has greatly promoted the development of communication power. High frequency miniaturized switching power supply and its technology have become the mainstream of modern communication power supply system. In the field of communication, the rectifier is usually called the primary power supply, and the direct current-direct current (DC/DC) converter is called the secondary power supply. The role of the primary power supply is to convert the single-phase or three-phase AC power grid into a DC power supply with a nominal value of 48V. In the primary power supply for program-controlled switches, the traditional phase-controlled regulated power supply has been replaced by a high-frequency switching power supply. Controlled in the 50-100kHz range for high efficiency and miniaturization. In recent years, the power capacity of switching rectifiers has been continuously expanded, and the single-unit capacity has been expanded from 48V/12.5A, 48V/20A to 48V/200A, 48V/400A.
The high-voltage power module will generate a very high voltage during operation. If someone touches it, the consequences are unimaginable. In order to ensure the safety of employees and avoid safety risks, it is necessary to understand the insulation when purchasing high-voltage power supplies. Only by ensuring that the insulation is good enough, can some unnecessary troubles be avoided.
