　　1. Understand AC-DC power supply: the core of energy conversion of modern electronic equipment

AC-DC power supply is a device that converts AC grid power into DC power. As the power core of various electronic equipment, its performance directly affects the stability and reliability of the entire system. With the rapid development of power electronics technology, modern AC-DC power supplies have developed from simple rectifier circuits to complex systems integrating efficient conversion, intelligent management, and multiple protections.

Our AC-DC power supply products adopt advanced topology structures and control algorithms, reaching industry-leading levels in terms of conversion efficiency, power density and reliability. Whether it is industrial equipment, communication systems or consumer electronics, we can provide the most suitable power solutions.

　　5. Frequently Asked Questions

　　Q1: How to choose a suitable AC-DC power supply?

The following key factors need to be considered when choosing:

Power requirements: Calculate the maximum power consumption of the system and reserve 20-30% margin

Input voltage range: Select according to the power grid standard of the area of ​​use

Safety certification: Ensure compliance with the safety requirements of the target market

Environmental conditions: consider environmental factors such as temperature, humidity, vibration, etc.

Size restrictions: Choose the appropriate package form according to the installation space

　　Q2: What is the service life of the power supply?

Under rated working conditions, the design life of our products is as follows:

Industrial grade: >100,000 hours (about 11.4 years)

Medical grade: >80,000 hours (about 9.1 years)

Commercial grade: >50,000 hours (about 5.7 years)

The actual service life is affected by factors such as operating temperature, load conditions, and environmental conditions.

　　Q3: Can multiple power supplies 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 power supply?

Effective cooling measures include:

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

Use with reduced capacity in high temperature environments

Install a cooling fan if necessary

Avoid centralized installation of multiple heat sources

Ensure good ventilation conditions
