MEAN WELL APV & APC Series LED Power Supplies
Series Overview
The APV and APC series are MEAN WELL’s foundational "economical" LED power supplies. They are specifically designed for indoor LED lighting applications where compact size and cost-efficiency are critical.
- Class II Design: These units utilize a plastic enclosure with a Class II design (no earth pin), making them safe and easy to install in a variety of indoor environments.
- Compact Footprint: Designed for small-space integration, such as inside light boxes, small signboards, or narrow LED channels.
- Reliable Protection: Equipped with industry-standard protections, including Short circuit, Overload, and Over voltage.
- Convection Cooling: Fanless design ensures silent operation and high reliability without the risk of mechanical fan failure.

Selection Guide: APV vs. APC
Understanding the difference is critical for ensuring your LED system functions correctly.
| Series | Mode | Best For |
|---|---|---|
| APV Series | Constant Voltage (CV) | LED Strips, LED modules with built-in resistors, signage with multiple parallel LEDs. |
| APC Series | Constant Current (CC) | Direct driving of LED chips or high-power LED strings that require a specific current (mA) to operate. |
Important Note: If your LED load has its own driver or resistor, use the APV (Voltage) series. If you are powering bare LEDs or strings that require a specific current limit, use the APC (Current) series.
Design Benefits
Why choose APV/APC for your project?
- Cost-Effectiveness: These series utilize a streamlined circuit design to offer the best value for budget-conscious projects.
- Maintenance-Free: With no moving parts like cooling fans, these units are ideal for hard-to-reach installations where maintenance would be difficult.
- Global Versatility: The universal AC input (90-264VAC) allows these units to be deployed in almost any region in the world without modification.
- Certifications: Despite their economical focus, they retain essential global safety certifications, ensuring compliance with building codes and international standards.
Usage Tip: Ensure adequate ventilation around the power supply. Even though they are conduction-cooled, heat buildup can shorten the lifespan of electronic components. Avoid installing them in completely sealed, unventilated boxes.
