The purchase of DC conversion power supply should be cautious(1)
Inverter module power supply
High frequency inverter rectifier welding machine power supply is a new type of welding machine power supply with high performance, high efficiency and material saving, which represents the development direction of current welding machine power supply. Due to the commercialization of IGBT large-capacity modules, this power supply has a broader application prospect.
Most of the inverter welding machine power supply adopts the method of AC-DC-AC-DC (AC-DC-AC-DC) conversion. The 50Hz alternating current is converted into direct current by full-bridge rectification, and the PWM high-frequency conversion part composed of IGBT inverts the direct current into a high-frequency
The purchase of DC conversion 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, 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.
