Industrial Converter Solutions Manufacturer - Factory-Direct VFD Filters & Reactors
LTECPower’s converter solutions are engineered to offer you optimized drive systems and eliminated harmonics from Variable Frequency Drives (VFDs). By preventing motor insulation failure, our converter solutions keep your industrial applications running reliably.
Industrial Converter Solutions - Advanced VFD & Motor Protection Systems
Bridges the gap between advanced motor drive systems and long-term asset reliability, LTECPower offers you a comprehensive suite of converter solutions. With 20 years of technical expertise and rigorous German engineering, our converter solutions tackle the most intractable VFDs challenges, such as reflected waves, bearing currents, and motor noise, helping your systems run smoother and last longer.
As a Sino-German joint venture, LTECPower operates a 20,000㎡ state‑of‑the‑art facility. Not just a trading company, we cover a fully integrated supply chain, from phase‑shifting rectifier transformers to DC filter reactors, and we control every step: R&D, production, and testing.
Managing submersible pumps in the oil field or overseeing complex HVAC systems now? Engineered to international standards, our converter solutions keep your system IEEE‑compliant and extend the life of your motors and drives.
Sine Wave Filters - Clean Power for Long Motor Cables
Converting your VFD’s PWM output into a pure, smooth sine wave, LTECPower’s sine wave filters eliminate the high-frequency motor noise and prevent the voltage spikes (reflected waves) that cause insulation failure. Essential for cable runs over 100 meters, our filters are the go-to choice for submersible pumps, HVAC systems, and long-distance industrial drives. With reduced eddy current losses, lower bearing currents, and motors that run quieter, last longer, and stay trouble‑free, our sine wave filters can be applied even in the most demanding applications.
DC Reactors - Cost-Effective Harmonic Suppression for Your Drives
Smoothing the DC link current in your VFD, LTECPower’s DC Reactors significantly reduce the input‑side harmonics (THDi) and protect bridge rectifiers from voltage surges. With improved power factor, reduced ripple current in DC bus capacitors, and a longer operational life for your drive, our DC Reactors are the smart choice for your harmonic control.
Dry-Type Phase-Shifting Rectifier Transformers - Clean Power Conversion
Designed for 12‑pulse, 18‑pulse, or 24‑pulse rectification systems, LTECPower’s phase-shifting transformers eliminate your low-order harmonics before they ever reach your grid. By creating precise phase shifts – ±15°or ±20°, the transformers cancel harmonic currents at the source, keeping your power clean and your system compliant. Built as dry-type, our transformers deliver you exceptional fire safety and zero maintenance, making them the ideal choice for demanding applications like marine propulsion, mining, and heavy manufacturing.
Solving Motor Insulation Failure in Long-Distance Pump Applications
In watertreatment, oil & gas, and other demanding industries, motors are often situated hundreds of meters from their drives. The distance creates “reflected waves” – voltage spikes, that will double at the motor terminals and cause rapid insulation failure. LTECPower’s sine wave filters eliminate your high dV/dt transients and support cable runs up to 1,000 meters by smoothing your VFD output into a pure sine wave. It keeps your motor protected.
Reducing Audible Noise and Bearing Currents in HVAC & OEM Machinery
VDF switching often cause magnetostrictive hum and parasitic bearing currents, leading to the premature mechanical failure. LTECPower’s converter solutions, including output reactors and sine wave filters, eliminate your high‑frequency harmonics responsible, that keeps your equipment quiet with less maintenance.
FAQ
How Can I Stop My VFD Motor from Making a High-pitched Whistling Noise With LTECPower's Converter Solutions?
LTECPower’s sine wave filters convert your VDF’s output into a smooth sine wave, eliminating your magnetic vibrations and harmonic noise at the source. You may get a quieter motor, and more comfortable workspace with no more whistling.
When Should I Use a Sine Wave Filter Instead of a dV/dt Filter?
For cables runs from 100 to 150 meters, you may opt for a dV/dt filter. However, if your cable exceeds 150 meters, or if you need to eliminate motor noise and eddy current losses, you may choose our sine wave filter, for cleaner power.
What Is the Benefit of Adding a DC Reactor to My Frequency Converter?
LTECPower’s DC reactors (also known as DC link chokes) reduce input harmonics, improve your power factor, and protect your drive’s internal components against power surges for a more efficient, and reliable drive with longer life for your system.
Why Are Phase-shifting Transformers Used In Large Rectifier Systems?
By creating precise phase shift, LTECPower’s phase-shifting power transformers cancel low-order harmonics like the 5th and 7th, before they enter your power grid.
Can LTECPower Provide Equivalent Filters for Schaffner or TCI Brands?
Sure. Specializing in cross-referencing major brands, LTECPower delivers you high‑performance alternatives that match or exceed original specs, with same quality and shorter lead times.
