Input Chokes (Line Reactors) and Output Chokes (Load Reactors)

The use of line and load reactors increases the reliability, performance, and efficiency of Drive systems and extends the
life of both the Drives and Motors.

Line Reactors are Connected in series with the incoming power supply line and is recommended when the power supply is more than 600kVA, 10 times the Drive capacity, unbalanced or when power factor is poor.

Load Reactors are used for operating ‘Non-Drive duty’ Motors or when the length of wiring between the Drive and Motor exceeds 50 metres (can consider from 25 metres).

SineWave Filters

AC motors operate at their peak efficiency when they run on clean sinusoidal power. VSDs/Solar Drives produce square waves that are modulated so that the pulse width of the square waves can be varied continuously (known as pulse width modulation - PWM). VSDs/Solar Drives maintain fine control over the width and amplitude of the square waves so that they take on the appearance (as viewed on an oscilloscope) of good approximations of a sine wave. Yet, even the most sophisticated VSDs/Solar Drives fail to match the purity of a true sine wave. Installing a sine wave filter between the VSD/Solar Drive and the motor itself ‘smooths’ the VSD's/Solar Drive's PWM signal and converts it into a nearly perfect sinusoidal power wave form.

To be installed for applications using older motors, applications in ‘aggressive’ environments, applications requiring frequent braking, 690V applications with general purpose motors and applications where cable lengths between the VSD/Solar Drive and motor is 150 to 500 metres (can reach 3000 metres).

TCGC offers the following SineWave Filters:

EM-SWF2 (3-Phase ~220V)
EM-SWF3 (3-Phase ~380V)
EM-SWF5 (3-Phase ~525V)
EM-SWF6 (3-Phase ~690V)
