　　1. AC-DC converter: the source of power for modern electronic equipment

AC-DC converter is a power conversion device that converts alternating current (AC) into direct current (DC). As the power core of electronic equipment, its performance directly affects the stability and reliability of the entire system. With the development of power electronics technology, modern AC-DC converters have developed from simple rectifier circuits to complex systems integrating efficient conversion, intelligent control, and multiple protections.

Our AC-DC converter products adopt the latest topology structure and control algorithm, reaching industry-leading levels in terms of conversion efficiency, power density and reliability, providing stable and clean DC power supply for various application scenarios.

　　2. Frequently Asked Questions: Solve users’ core questions

　　Q1: How do I choose the right AC-DC converter for my application?

The following factors should be considered when choosing:

Power requirements: Calculate the maximum power consumption of the system and reserve 20% margin

Input voltage: Select the appropriate range according to local power grid standards

Safety standards: Different fields such as industry, medical care, communications, etc. have specific certification requirements

Environmental conditions: Temperature, humidity, vibration and other environmental factors affect the selection of components

Size restrictions: The installation space determines the choice of packaging form

　　Q2: How long is the service life of the converter?

Under rated working conditions, the design life of our industrial-grade products is 100,000 hours (approximately 11.4 years). Actual life is affected by operating temperature, load conditions, environmental stress and other factors. suggestion:

​Control the operating temperature within the specification range

Avoid running at full load for a long time

Regularly clean radiator dust

Ensure good ventilation and heat dissipation

　　Q3: Can multiple converters be used in parallel?

Some models support parallel operation, but please note:

Choose a model with current sharing function

Use balanced cables to ensure even distribution of current

The total output power does not exceed the maximum capacity of a single unit × the number of units × 0.9

It is RECOMmended to consult technical support for specific parallel connection solutions.

　　Q4: How to solve the heat dissipation problem of the converter?

Effective cooling measures include:

Keep enough space for heat dissipation (recommended to be greater than 5cm)

Use with reduced capacity in high temperature environments

If necessary, install a cooling fan or heat sink

Avoid centralized installation of multiple heat sources
