At Merus Power, we believe in delivering power-quality solutions that go above and beyond. With Merus® A2-Active Harmonic Filter, we offer highly customizable options and advanced capabilities, making it a top choice for industries seeking efficient and sustainable power quality management.
AFE drives vs. active harmonic filter: The dilemma
When exploring active alternatives for harmonic solutions for Variable Frequency Drive (VFD) applications, two options often come to the forefront – AFE drives and active harmonic filters. However, choosing the right technology can significantly impact your operations, costs, and overall power quality.
Merus® A2 – Active Harmonic Filter
Merus® A2 is a scalable, versatile, and durable active harmonic filtering solution designed and manufactured in Finland using innovative Merus® technology.
AFE drives: Complexity and risks
When opting for AFE drive technology, each motor is controlled by a drive with a combination of an IGBT rectifier, an IGBT inverter, and an LCL (inductor-capacitor-inductor) filter. Although major drive manufacturers may offer an AFE drive as quite a compact package, it essentially is a double drive construction with a larger footprint in comparison to a standard six-pulse drive.
This translates to a more complex design and installation process, involving a larger number of components and inevitably leading to an increased risk of hardware failure. The consequences? Escalating costs, downtime, and added risk to your operations.
Merus® A2: Efficiency and reliability
On the other hand, Merus® A2-Active Harmonic Filter follows a different path. It is always installed in parallel with the loads and sized according to your specific needs. It stands as a compact and effective solution, boasting higher system redundancy. This parallel installation ensures reliability for your process. In the event of an active harmonic filter fault or failure, harmonic mitigation may cease, but VFD-controlled motors and the manufacturing process will not stop – unlike with AFE technology. Additionally, the smaller size of Merus® A2 not only saves valuable space but also results in lower losses, making it the sustainable choice for power quality management.
Tailored to efficiency: The advantages of Merus® A2
With Merus® A2, customization is the key to success. We understand that each industry and application has unique power quality requirements. Thus, our solution is designed to be tailored precisely to your needs, ensuring maximum efficiency and optimization.
When it comes to selecting your harmonic solution, it’s essential to prioritize uptime, cost-efficiency, and space-saving. Merus® A2 checks all these boxes with finesse, providing you with a reliable and robust power quality management system.
