A major production facility of Quanta Computer, a global leader in laptops, tablets, and digital devices, has successfully addressed serious power quality issues through the deployment of a modular Active Power Filter (APF) solution.
⚙️ Project Overview
Located in Thailand, this 3C electronics manufacturing plant operates around the clock with a high concentration of single-phase electronic equipment. Over time, the site encountered:
-
High 3rd harmonic distortion, primarily caused by nonlinear loads
-
Excessive neutral line current, often triggering breaker protection
-
Increased risk of equipment overheating and unplanned downtime

Thailand-Active Power Filter (APF)
✅ Enjoypowers’ APF Solution
To solve these challenges, the factory deployed 12 sets of 100A rack-mounted APF modules from Enjoypowers, forming a total compensation capacity of 1200A. These APF units operate in parallel, offering:
- Flexible scalability
- Space-saving rack-mounted design
- Fast dynamic response to harmonic fluctuations
🚀 Key Benefits
-
Significant reduction of 3rd harmonic currents
