Brand: Sanhe

Product introduction

The sinusoidal filter is mainly used to solve the harmonic problem at the output end of VFD. It converts the PWM wave of the motor into smooth sine wave with low residual ripple voltage, prevents damage to the winding insulation of the motor ,reduces the phenomenon of distributed capacitance and distributed inductance resonance caused by the cable length, and reduces the audible noise of the motor. At the same time, it can realize the long-distance transmission of VFD.

Feature

1. An L-C power filter circuit with:

A 3-phase reactor
High-endurance, harmonic-rated capacitors
Compression terminals for ease and integrity of all power wiring
Thermal switches on reactor is optional
Suitable for all lead lengths extending up to 3,000 feet

1. High performance H grade insulation material is used.
2. Withstanding extremely high Dv/Dt voltage shock.
3. Product loss is small, audible noise is small.
4. Strong anti-electromagnetic ability, short time overload ability.
5. Improving power quality, harmonic voltage distortion content reduced to 5%

Product Description
SWFSH is a 3-phase low-pass sine wave filter designed and developed to deliver conditioned power to motor loads driven by PWM drives with switching frequencies from 2 kHz to 16 kHz. Any drive control parameter which has the effect of reducing the carrier or switching frequency below 2 kHz at any time must be disabled. Some sine wave or long lead mode drive parameters or operating modes can have this effect. This filter is suitable for VFD drives configured to Volts per Hz modes only. Available for three phase voltage systems up to 460/480 Volts, the SWFSH is a passive LC filter connected in series with the output terminals of the variable frequency drive. This design removes the carrier frequency distortion from the output voltage waveform resulting in a nearly pure sine wave voltage profile.
SWFSH sine wave filter reduces the effects of the reflected wave phenomenon (dV/dt),
which can cause motor heating, insulation damage, and excessive audible noise. The reduction
of high frequency VFD output currents extends the life of motors and transformers and eliminates
the need for special motor cables. The SWFSH reduces VFD ground fault problems and
noise interference in transducer signals caused by stray high frequency harmonic currents.
