The purchase of DC conversion power supply should be cautious(1)
The purchase of DC conversion power supply should be cautious, and the flame retardant performance should not be ignored
(2) Parallel connection of redundant hot backup. Connecting the output terminals of the same module through diodes in parallel can enhance the output capability and improve the reliability of the power supply system. In principle, if it cooperates with the corresponding output alarm circuit, put the module on the busbar that can be removed, so that the faulty module can be replaced in time. There is no limit to the number of modules connected in parallel in this way. D is generally a Schottky diode.
(3) Series expansion. Connecting the output terminals of the same module in series can double the output voltage and increase the power accordingly, and the series output terminals must be connected with diodes for protection.
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, DC conversion 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 DC conversion power supply otherwise it is very likely that the gain will outweigh the gain.
