RF4 PWM
Multifrequency PWM series
Squeeze maximum throughput from every feeder – automatically. The RF4 PWM is a microprocessor-based digital multifrequency controller that digitally regulates both amplitude and frequency and actively searches for the feeder’s resonance frequency, delivering peak performance with lower power draw and no lengthy mechanical calibration.
It drives linear and bowl feeders up to 5 A at 115/230 V, at 30–130 Hz (RF4PWM and /K versions) or 50/100 Hz ±12 Hz (/B and /BD versions), 3000/6000 vpm, with PLC automatic input (0/10V-0/20mA; not on the /K version), NPN/PNP or relay sensor control and adjustable ON/OFF delay. Available with display, keys, single potentiometer or as a bare DIN35 circuit, and up to IP65 (NEMA 4/4X) in the boxed version.
Description
Microprocessor digital professional controller with visualized frequency (optional). This controller is available in a metallic box with two potentiometers and display, with keys and display, with a single potentiometer without display, or as a circuit on DIN35.
Application: digital regulation of linear and bowl feeders till 5 Amps. The RF4 PWM optimises feeder operation by searching for its resonance frequency (maximum performance), eliminating its lengthy and difficult mechanical calibration.
