Digital PWM controllers that regulate amplitude and frequency and automatically search the feeder’s resonance frequency, eliminating the lengthy mechanical calibration. Two lines: FQ1 PWM up to 6 A (12/15 A and 400 V on the /HC) and RF4 PWM up to 5 A, with parts-shortage alarm, air blow and 80÷260 V universal input on the /N.
