Revcon Harmonic Passive Filter

The Revcon Harmonic Filter (RHF-5P and RHF-8P) is a passive double-stage filter designed to reduce Total Harmonic Distortion (THDi) in variable frequency drives (VFDs) and other non-linear loads. This filter effectively lowers THDi to below 5% even under challenging conditions, ensuring compliance with standards such as IEEE 519-2014.

Benefits of RHF-Passive:

• High Performance: The patented double-stage filter circuit offers smooth damping of harmonics up to the 200th order, significantly reducing distortion in real-world applications.
• Full Drive Power: The RHF-Passive maintains 100% DC-bus voltage at full drive load, eliminating the need for de-rating and ensuring maximum drive performance.
• High Efficiency: Achieves up to 99.5% efficiency, with power losses up to 70% less than comparable <5% THDi solutions.
• Compact and Reliable: The enclosed design results in a smaller, more reliable product with a typical lifespan of 15 years or more, thanks to the cooler core temperature of the capacitors.
• Easy Integration: Compatible with any standard 6-pulse VFD, the RHF-Passive is easy to install and can be used across a wide range of applications.

Why Choose RHF-Passive?

• Versatility: Suitable for a variety of applications, including pumps, compressors, and ventilation systems, the RHF-Passive can be used with multiple drives connected to a single filter.
• Cost-Effective: The compact size and high efficiency of the RHF-Passive reduce both production and transport costs, making it a cost-effective solution for harmonic mitigation.
• Durability: Designed for long-term use, the RHF-Passive offers a typical lifespan of 15 years or more, making it a reliable choice for continuous operation environments.
• No De-Rating Required: The RHF-Passive eliminates the need for VFD de-rating due to voltage drops, ensuring optimal performance without unnecessary oversizing.
