CEMarked CEMarked Explore our heavy-duty EMI/RFI suppression portfolio, standard chassis modules, and precision-wound inductors calibrated for demanding manufacturing plants across Rayong, Chonburi, and Greater Bangkok.
As Thailand surges ahead with its Thailand 4.0 policy and expands heavy industrial automation within the Eastern Economic Corridor (EEC), electrical power systems encounter severe noise pollution. Variable Frequency Drives (VFDs), computerized CNC machinery, servo systems, and high-frequency welding stations generate substantial common-mode and differential-mode noise. Without correctly specified EMI/RFI power line filters and reactive magnetic components, this noise conducts back into the grid or radiates across control instrumentation, precipitating intermittent communication errors, PLC logic trips, and catastrophic machine downtime.
Operating a specialized manufacturing facility spanning over 5,500 m², our engineering organization provides a comprehensive spectrum of electromagnetic compatibility components, line reactors up to 2500A, and customized harmonic solutions up to 500HP. Originating from an automation lineage established in 1990—where the parent company engineered complex PC, PLC, and SCADA-based systems, including pressurized explosion-proof panels—we build our EMI filters with an innate understanding of panel dynamics, thermal management, inrush tolerance, and rigorous field performance.
Engineered to withstand Southeast Asian tropical climates, high ambient humidity, and severe electrical noise environments.
Protecting automated robotic assembly lines, welding machinery, and DC fast-charging infrastructure across Rayong and Chonburi from electrical noise that disrupts CAN-bus, Profinet, and sensor communication.
Feedthrough ceramic EMI filters and board-level toroidal common-mode chokes prevent micro-volts of high-frequency ripple from degrading wafer handling, precision testing equipment, and SMD lines in Pathum Thani.
Heavy refrigeration, sorting VFDs, and bottling plants experience line voltage fluctuations. Our 3-phase line filters and load reactors prevent high dv/dt breakdown, extending motor winding insulation life.
For installations in Map Ta Phut, our sealed filters and heavy-duty line reactors safely suppress electrical noise inside continuous production facilities, built under rigorous industrial manufacturing standards.
Grid-tied commercial rooftop and utility-scale solar farms across central Thailand leverage our DC and AC EMI filters to clean switching noise prior to utility grid interconnection, complying with MEA and PEA codes.
Supplying standard DIN-rail and chassis mount single and three-phase filters with compact dimensions, touch-safe screw terminal blocks, and comprehensive CE export compliance credentials.
Rapid adoption of modern power electronics across ASEAN industrial plants has accelerated grid pollution. The Metropolitan Electricity Authority (MEA) and Provincial Electricity Authority (PEA) of Thailand have progressively tightened power quality stipulations regarding Total Harmonic Distortion (THD) and conducted emissions. In parallel, global machine builders exporting equipment into Europe, Japan, and North America from manufacturing bases in Thailand must guarantee compliance with EN/IEC 61800-3, CISPR 11, and CE EMC Directives.
| Grid Requirement / Challenge | Underlying Root Cause | Engineered EMI/Magnetic Solution |
|---|---|---|
| Conducted RFI Emissions (150kHz–30MHz) | Fast switching IGBTs and PWM rectifiers in motor drives | Dual-stage 3-phase EMI power filters with high CM/DM insertion loss |
| Reflected Wave & Motor Bearing Currents | Excessive motor cable runs between VFD and motor (>30m) | Output load reactors (dv/dt reduction) and sinusoidal output filters |
| EV Fast-Charger Power Fluctuations | Megawatt active power factor correction (PFC) stages | High-current 3-phase 4-line noise filters (up to 440VAC / 300A+) |
| Tropical High-Humidity Degradation | Ambient humidity >85% causing leakage or tracking failure | Vacuum pressure impregnated (VPI) coils & hermetic feedthrough potting |
Procurement teams and electrical project heads must weigh these factors to avoid buying consumer-grade line filters that saturate prematurely under peak plant loads. An industrial-grade EMI filter must maintain attenuation performance without overheating during sustained load periods.
Built upon 25+ years of design, winding, assembly, and testing heritage to fulfill stringent international procurement standards.
Originating as a subsidiary of an industrial automation leader established in 1990, our filters reflect practical installation realities: ample cable clearance, minimal heat generation, and rugged terminal blocks.
Every batch undergoes automated computerized routine checks, including Megger insulation resistance, double voltage double frequency (DVDF) stress, digital LCR inductance testing, and milli-ohm winding validation.
All power line suppression devices and magnetic reactors are manufactured to conform strictly to global electrical safety standards and CE directives, ensuring seamless export acceptance across ASEAN and beyond.
Key technical and logistics considerations for Thai plant managers, systems integrators, and procurement directors.
