EMIS, a global leader in electromagnetic compatibility (EMC) and power quality solutions, has announced the release of its TPQS3113 Three-Phase Sinewave Filter, designed to improve power quality, protect connected equipment, and extend operating lifetimes in demanding industrial applications.
Modern compact variable frequency drives (VFDs) that utilize high-speed IGBT switching transistors generate significant harmonic distortion. The TPQS3113 filter smooths these pulse width modulated (PWM) signals into near-perfect sinewaves, providing dV/dt protection, reducing motor losses, and increasing load efficiency. This results in longer motor lifespans, enhanced system reliability, and reduced downtime.
In addition to motors, the TPQS3113 also benefits other sensitive equipment such as computers, power converters, and automation systems by minimizing voltage and current waveform distortions.
Key Benefits:
- Extended Motor Life – mitigates bearing currents, reduces insulation stress, and minimizes wear on motor cables.
- Improved Reliability – ensures stable power delivery in harsh industrial environments with high ambient temperatures, vibrations, dust, and heavy electrical loads.
- Noise and Harmonics Reduction – particularly effective in HVAC systems, renewable energy installations, and automation equipment.
Typical Applications Include:
- Motor drive systems with long cable runs (up to 2000 m)
- HVAC fan and pump motors.
- Wind and solar inverters for grid compatibility.
- Precision manufacturing and robotics in industrial automation.
- Pumps, compressors, elevators, and escalators.
Technical Specifications of the TPQS3113:
- Operating voltage: 480 VAC.
- Current rating: 2.3 A to 1,000 A.
- Frequency: 50 Hz.
- Insulation: Class F.
- Protection category: IP00.
