The CUH SDVC31-M is an intelligent digital controller for vibratory feeders that delivers precise voltage and frequency regulation across automated material handling systems. Operating from 85–260 VAC input, the unit outputs 0–250 V or 0–260 V at frequencies between 40.0 Hz and 400.0 Hz, with a 3.0 A current rating. Automatic voltage regulation compensates for mains fluctuations and industrial AC beat effects, while soft startup gradually ramps output voltage to prevent shock loads on workpieces. Maximum output can boost to 150% of input voltage, and harmonic frequency tuning optimizes vibrator amplitude for specific applications.
