Excellent harmonic mitigation with guaranteed compliance
Merus™ Active Harmonic Filters deliver a real-time response to power quality problems. They sense the harmonic distortions created by the non-linear loads in the network and provide an effective and real-time response to cancel harmonic distortions. Merus™ A2-series Active Filters ensure a guaranteed compliance with the harmonic distortion limits specified in IEEE 519, G5/4, EN 50160 and also other power quality standards and recommendations.
Automatic voltage and frequency sensing with smart operation mode
Merus™ Active Harmonic Filters come with several advanced features. When connected to the network, they automatically sense the voltage and frequency, simplifying the order and delivery processes. Merus™ A2- series Active Harmonic Filters are also equipped with the built-in smart operation mode. Under low load conditions, the smart operation mode automatically turns off the IGBTs and fans reducing the operational losses and extending the lifetime of the active harmonic filters.
Unlimited scalability
Unlimited scalability can easily be achieved with Merus™ A2-series Active Harmonic Filters in both; open-loop as well as closed-loop connections. Higher harmonic compensation capacity can be achieved by adding A2-series Active Harmonic Filters modules in parallel without any technical limitations. This gives flexibility to facility engineers when more loads are added in the facilities.
Customizable functionality with several built-in operation modes
Merus™ Active Harmonic Filters are extremely flexible devices. Merus™ Active Harmonic Filters functionalities can be customized anytime with a modern touch screen Human Machine Interface (HMI) to meet customer requirements. This allows Merus™ Active Harmonic Filters to adapt to the changes in the loads. Customer can choose if they want to cancel all the harmonics up to 50th order, or only the selective ones. Furthermore, output capacity of Merus™ Active Harmonic Filters can be flexibly used to control voltage variations, flicker mitigation, load balancing and power factor improvement.
Compact design and ease of integration
Standard A2-series Active Harmonic Filter is in IP20 protection class module. Extremely compact size allows easy integration into variable speed drives (VFDs) or capacitor bank cubicles. Merus Power can also deliver active harmonic filters in IP42, IP54 or others degrees of protection upon request. Furthermore, A2-series Active Filters can also be delivered in stand-alone wall-mounted design.
Extremely low noise harmonic filtering solution
Pollution comes in many forms: harmonics pollute the electrical power system, and high audible noise pollutes and disturbs people working in close proximity. Merus™ A2-series Active Filters, enabled by 3-level topology, release the lowest possible audible noise among all active filters. Designed with high switching frequency and special inductor core material, Merus™ A-2 series Active Filters can be installed into spaces where silence is vital.
