Elscint Automation now offers soft-start electronic controllers for vibratory feeders.

Two models are available: the E3FC, rated up to 360VA (mainly for linear feeders and smaller sized bowl feeders); and the E5FC, rated up to 800VA (for bowl feeders and large linear feeders).

The controllers are specially designed for controlling the amplitude of vibration in industrial electromagnetic vibrators.

The system is based on an integrated circuit that guarantees perfect synchronisation of the triac firing pulse with the waveform of the working voltage under all conditions.

The controllers also include a suitable circuit for soft start with provision for choosing the ramp time (0.2-2s) and for temperature compensation of the phase angle.

Appropriately overspecified power stages are provided to handle any overloads without interruption, whether operating at 50 or 60Hz.

Highly linear adjustment, as well as provision for setting the maximum and minimum vibration limits complete the list of main features embodied in the series E controllers.

Vibration regulation is through an external potentiometer and on/off type control with external low power contact for a weighing and batching system.
