RF4 PWM family
Amplitude-frequency controllers up to 5 A · RF4 PWM and the new RF4 PWM/N
The two lines share the same enclosures and most functions. RF4 PWM/N adds the 80–260 V wide-range input, the max current limit and the Min/Max setting; RF4 PWM keeps the fill-level control and the air-blow output. Below, only what changes between the versions.

FQ NG series
Digital amplitude-frequency controllers with SIND3 amplitude sensor · FQ1NG · FQ2NG · FQ3NG
Same control platform across the three series. They differ in output current, display, sensors and enclosure: FQ1NG and FQ2NG are the complete versions, up to 16 A in a metal enclosure and up to 8 A in a compact aluminium one; FQ3NG is the essential version, up to 8 A, with a single PNP sensor and fewer functions.
