Engineered for extreme reliability, grid-code compliance, and high efficiency across industrial, automotive, and renewable applications in Denmark and the Nordic region.
Denmark stands as a global vanguard in renewable energy integration, electrified district heating, maritime decarbonization, and hyper-scale data center infrastructure. However, the aggressive transition toward green power networks brings severe electrical power quality challenges. The exponential influx of non-linear loads—such as variable frequency drives (VFDs) in wind turbine pitch control, megawatt-scale electrolyzers for Power-to-X (PtX), continuous heat pumps, and solid-state charging stations—introduces destructive high-order voltage and current harmonics into the national grid managed by Energinet.
As a leading Chinese original equipment manufacturer (OEM) and custom power conversion engineering hub, our facility bridges high-capacity, cost-effective manufacturing with elite Western engineering compliance. Supplying Danish industrial system integrators, offshore engineers, and facility directors requires strict compliance with international standards including IEC/EN 61000-3-12, EN 50160, IEEE 519, and Danish local grid operational codes (TF 3.2.1 and TF 3.3.1).
Our Active Harmonic Filters dynamically inject compensating current in real time (within 100 microseconds), cancelling harmonic orders from the 2nd up to the 50th harmonic. This guarantees Total Harmonic Current Distortion (THDi) remains well beneath 3% to 5% even under volatile load profiles.
Unlike conventional static capacitor banks that risk resonance with grid inductances, our active filtering architecture seamlessly provides bi-directional inductive and capacitive reactive power compensation (power factor correction to 0.99) instantly balancing neutral current zero-sequence harmonics.
From maritime platforms in Esbjerg to data centers in Høje-Taastrup, our power converters and active filtering modules are optimized for harsh climate operational longevity.
Offshore wind substations in the North Sea and Baltic Sea experience immense voltage fluctuations, catenary surges, and severe salt mist exposure. Our custom IP67-rated DC/DC voltage converters and active power quality modules utilize conformal coating and isolated planar magnetics, delivering reliable auxiliary power to wind turbine nacelles, pitch controllers, and marine navigation arrays while preventing harmonic distortion from back-feeding into the main transformer sub-station.
Denmark's ambitious Green Hydrogen roadmap relies on high-power rectifiers and DC buck converters supplying continuous multi-megawatt electrolyzers. High current ripple drastically reduces stack longevity and electrolyzer efficiency. Our active filter modules mitigate AC side harmonics while our multi-phase buck converters provide ultra-low ripple DC power supply, maximizing stack performance and maintaining compliance with Danish Energinet connection points.
Large-scale municipal heat pumps and water distribution networks across Aarhus, Odense, and Copenhagen rely on massive VFD installations. The resulting 5th, 7th, 11th, and 13th harmonic currents overheat distribution transformers and trip sensitive relay protections. Deploying our modular 3-level NPC Active Harmonic Filters directly at the motor control center (MCC) eliminates transformer overheating and drastically reduces energy losses.
Modern Nordic data centers require uncompromised sine-wave purity, strict voltage stability, and rapid battery back-up transition. Utilizing our pure sine wave bi-directional inverters, wide input DC/DC power modules, and IoT-supervised static transfer switches, critical infrastructure managers obtain redundancy, zero phase-shift switching, and remote thermal/telemetry diagnostics in real-time.
Choosing the correct power quality strategy is vital for operational safety, energy efficiency, and total cost of ownership (TCO) in industrial plants. Below is an engineering benchmark comparing traditional passive LC filters against our advanced Modular Active Power Filters (APF/AHF):
| Performance Indicator | Traditional Passive LC Filter | Modular Active Filter (Our Factory Series) | Danish Industrial Grid Code Target |
|---|---|---|---|
| Harmonic Mitigation Scope | Single fixed harmonic (e.g., 5th only) | 2nd to 50th harmonic (Selectable filtering) | Full spectrum compliance (IEEE 519) |
| THDi Target Efficiency | 10% - 15% Residual THDi | < 3% Total Harmonic Current Distortion | < 5% at Point of Common Coupling (PCC) |
| Response & Compensation Time | Slow electromechanical response (>100ms) | Ultra-fast dynamic response (< 100 microseconds) | Real-time dynamic tracking required |
| Grid Resonance Risk | High risk of parallel/series resonance | Zero resonance risk (Active current injection) | Zero system disruption tolerated |
| Power Factor Compensation | Fixed capacitive power factor | Stepless dynamic reactive power (-1.0 to +1.0) | Target Cos φ ≥ 0.98 continuous |
| Modularity & Expandability | Bulky, rigid, non-scalable space demand | Hot-swappable 19-inch rack modules (50A - 150A) | Modular expansion for growing facilities |
With over four decades of deep power electronics heritage, our manufacturing hub combines rigorous European-level design protocols with high-throughput Chinese manufacturing scale. We specialize in transforming demanding client specifications—ranging from precise DC/DC steps, wide-range DC/AC sine-wave inverters, and board-mount converters to megawatt-scale active power filters—into certifiable, manufacturable, and enduring end products.
Bypass intermediary trading friction. Work directly with our power electronics application engineers to customize voltage inputs, mechanical chassis dimensions, IP ratings, and communication protocols (Modbus TCP, CANopen, Profinet).
Addressing compliance, supply chain logistics, custom NRE timelines, and operational reliability for Danish procurement teams.
Our Active Harmonic Filters (AHF) and inverter systems are engineered to satisfy global IEC 61000-3-12 and IEEE 519-2022 limits, as well as specific Danish grid connections (Energinet TF 3.2.1 for distribution networks). By monitoring current at the Point of Common Coupling (PCC) using precision CTs, the system cancels total harmonic current distortion (THDi) down to under 3%, preventing harmonic voltage distortion on Danish utility networks.
Standard catalogue products (such as board-mount AC/DC modules, portable car inverters, and IP67 DC/DC converters) ship within 3 to 7 business days. Custom modular active filters or high-power inverters require a 4 to 6-week production and assembly window. Air freight delivery to Copenhagen (CPH) or Billund (BLL) takes 5 to 7 days, while sea freight directly to Aarhus Port or Copenhagen Port arrives within 28 to 35 days under flexible DDP/DAP terms.
Yes. For offshore wind support vessels, port cranes, and coastal facilities, we supply specialized enclosures coated in accordance with ISO 12944 C5-M anti-corrosion standards. Internal printed circuit board assemblies (PCBAs) feature heavy conformal coating (acrylic or silicone-based) to guard against high humidity, salt fog, and industrial pollutants.
Our custom development loop spans 16 to 28 weeks from initial specification review to qualified samples. By leveraging pre-qualified internal building blocks—such as planar transformers, standardized digital DSP control boards, and resonant power stages—we drastically reduce NRE costs and accelerate certification campaigns (CE, Low Voltage Directive, EMC Directive).
Yes. Every modular filter shelf and active converter system can be equipped with integrated IoT gateways. They communicate natively via RS485 (Modbus RTU), Ethernet (Modbus TCP, SNMP), or CANbus, enabling continuous telemetry monitoring of grid voltage, harmonic spectrum (2nd to 50th), IGBT temperature, and alarm states directly to your plant SCADA or cloud predictive maintenance dashboard.
