MEAN WELL, founded in 1982, is one of the few manufacturers worldwide dedicated to standard power supply products. According to a report by Micro Technology released in March 2024, MEAN WELL is ranked 4th among global manufacturers of power supplies (DC output). The top three companies in this sector mainly generate their revenue through ODM/OEM, whereas MEAN WELL derives 99% of its revenue from standard power supplies, following a business strategy centered around its own brand, MEAN WELL.

What is an SMPS?

A switched-mode power supply (SMPS) is an electronic power supply that efficiently converts electrical power using switching regulators. Unlike traditional linear power supplies, SMPS units use high-frequency switching to achieve higher efficiency and smaller size.

How SMPS Works

AC-DC Conversion: The incoming AC power is rectified and converted into DC voltage.
High-Frequency Switching: A high-speed switching transistor converts the DC voltage into high-frequency AC.
Voltage Regulation: The AC is then rectified and filtered to provide a stable DC output.
Feedback Mechanism: A control circuit continuously monitors the output and adjusts switching to maintain voltage stability.

Mean Well SMPS Features

High Efficiency: Mean Well SMPS units achieve efficiency levels of up to 95%.
Compact Size: Advanced design reduces bulk, making them ideal for space-constrained applications.
Wide Input Voltage Range: Supports universal AC input (85V-264V) and various DC input ranges.
Overload & Short Circuit Protection: Built-in safety mechanisms prevent damage to connected devices.
Active PFC (Power Factor Correction): Ensures compliance with international energy efficiency standards.
Fanless & Low Noise Models: Available for applications requiring silent operation.
Reliability & Durability: Designed for long-term use with robust components and thermal management.

Technical & Installation Questions

4. How do I choose the right Mean Well SMPS for my application?

Consider the following factors:
🔹 Input voltage (AC or DC compatibility)
🔹 Output voltage & current requirements
🔹 Power rating (Wattage)
🔹 Environmental conditions (IP rating, cooling, operating temperature)
🔹 Mounting type (DIN Rail, enclosed, open frame, etc.)

5. What is the difference between constant voltage (CV) and constant current (CC) SMPS?

Constant Voltage (CV) Power Supply: Provides a stable voltage (e.g., 12V, 24V, 48V) and is commonly used for LED lighting, industrial automation, and electronic circuits.
Constant Current (CC) Power Supply: Supplies a fixed current and adjusts voltage accordingly, suitable for LED drivers and battery charging applications.

6. Can I use a Mean Well power supply for battery charging?
