What are the advantages of vehicle power supply module?(2)

Power active filter is a new type of power electronic device that can dynamically suppress harmonics. It can overcome the shortcomings of traditional LC filters and is a promising harmonic suppression method. The filter consists of a bridge switching power converter and a specific control circuit. The difference from the traditional switching power supply is: (1) not only feedback the output voltage, but also feedback the average input current; (2) the current loop reference signal is the product of the voltage loop error signal and the full-wave rectified voltage sampling signal.

(6) For the module power supply, some manufacturers have a fixed resistance directly connected to the adjustable terminal (ADJ) from the factory. When using, the user must configure a potentiometer with the corresponding resistance value to replace the fixed resistance. However, it should be noted that when the adjustable terminals are in an open state, loading is never allowed.
(7) In order to achieve sufficient heat dissipation, the module power supply should be installed in a location with better air convection. Generally, when the working current of the linear power supply is above 4A, or the working current of the switching power supply is above 7A, forced air cooling should be installed. In addition, no other items are allowed on the module power supply housing.
(8) The module power supply is generally suitable for resistive-based loads. If it needs to be applied to capacitive-based or inductive-based loads, it should be explained in the order contract in advance and customized by the manufacturer.

(1) It has a particularly wide range of uses, not only aerospace, post and telecommunications, but also metallurgy, mining, automatic control, etc., whether it is social production or daily life, it can be well used;

(2) vehicle LED advertising screen power supply module  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;

(3) The technology is relatively simple, and it is easy to meet the relevant requirements;

(4) vehicle LED advertising screen power supply moduleThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;

(6) vehicle LED advertising screen power supply module The design is relatively simple, without too many parts, just a power module and a few discrete components;

 In many fields, switching LED advertising screen power supply modules play a role that cannot be ignored and are very important.
