The purchase of DCDC converter should be cautious(1)
The purchase of DCDC converter 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, DCDC converter 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
(3) Before the installation is completed and the power is turned on, the wiring on each terminal should be checked and checked again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current values are correct. Prevent the occurrence of reverse and wrong connections.
(4) For high-power power supplies, there are generally two or more "+" output terminals and "-" output terminals. In fact, they belong to the same output electrode, but for the convenience of user wiring, they are connected together internally.
(5) The module power supply is not allowed to work at full load for a long time. The utilization rate of linear power supply should be controlled within 60%; the utilization rate of switching power supply should be controlled within 80%, otherwise it may cause early artificial failure of module power supply.
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 DCDC converter otherwise it is very likely that the gain will outweigh the gain.
