Variable Inductance-Current Limiting Reactor (VI-CLR)

Get Maximum Power For Better ESP Efficiency

The VI-CLR is designed to replace the smaller current limiting reactors in a precipitator power supply. The patented VI-CLR reduces distortion of the AC sine waves supplied to the transformer/rectifier (T/R) sets. The reduced wave distortion means higher average power levels and increased migration velocity of dust toward the collecting plates, resulting in better collection efficiency.

Reduce waveform distortion; boost performance

When your precipitator power supply operates at full power, the silicon-controlled rectifiers (SCRs) theoretically conduct for 180° If the connected load requires less than full power (such as during sparking) the voltage controls and SCRs clip part of the incoming sine wave, limiting conduction and thus reducing applied power. The output is no longer a pure sine wave because each half-cycle is "chopped" at the point in that half-cycle where the SCR was fired. The lower the power, the worse the waveform distortion.

The VI-CLR increases conduction time when the power supply in a field is operating below the rated limits of the T/R set. (Increased conduction time is shown by the red lines in the scope trace below.) Enhanced conduction boosts your average current, average voltage and corona power, all of which increase your collection efficiency.

Control leads from the voltage control to variable inductance winding provide rapid changes in reactance to follow conditions inside your ESP. Thick steel cores and air-cooled coils have up to four times the mass of standard power supply CLRs for the best possible waveform enhancement and control.
