The purchase of 110V input power supply should be cautious(1)
Power Active Filter
When the traditional alternating current-direct current (AC-DC) converter is put into operation, a large amount of harmonic current will be injected into the power grid, which will cause harmonic loss and interference. For example, when uncontrollable rectification is added with capacitor filtering, the third harmonic content on the grid side can reach (70~80)%, and the power factor on the grid side is only 0.5~0.6.
The purchase of 110V input power supply should be cautious, and the flame retardant performance should not be ignored
Electricity has become an indispensable item in people's daily life. If there is no electricity, people's lives will be greatly affected. At present, 110V input power supply are used in the production process of many mechanical equipment, but such power modules cannot be purchased at will. There are many problems in the procurement process that need to be paid attention to. If you purchase at will, you may buy inferior power supplies. modules, resulting in the appearance of stylistic product quality.
1. Flame retardant properties can not be ignored
Mechanical equipment will generate a lot of heat energy during use, especially in the current market competition is intensifying, in order to improve their market competitiveness, many companies continue to strengthen production, 24-hour production has become the norm, if the flame retardant power module Insufficient performance, long-term work may cause the spontaneous combustion of the power module, which may bring huge losses to the enterprise. Therefore, the flame retardant performance must not be ignored when purchasing a 110V input power supply otherwise it is very likely that the gain will outweigh the gain.
