The purchase of DCDC conversion module should be cautious(1)

The purchase of DCDC conversion module  should be cautious, and the flame retardant performance should not be ignored

Regulation of output voltage
For module power products with TRIM or ADJ (adjustable) output pins, the output voltage can be adjusted within a certain range through resistors or potentiometers, and the general adjustment range is ±10%.
For the TRIM output pin, connect the center of the potentiometer to TRIM. In all modules with +S and -S pins, the other two ends are connected to +S and -S respectively. When there is no +S, -S, connect the two ends to the output positive and negative poles of the corresponding main circuit (+S to +Vin, -S to -Vin), and then adjust the potentiometer. The resistance value of the potentiometer is generally more appropriate to use 5 ~ 10kΩ.

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 conversion module 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 DCDC conversion module otherwise it is very likely that the gain will outweigh the gain.
