INTRODUCTION

The vibrators power supply has been designed to keep in vibration the feeded system giving it

the necessary energy exactly when required.

The most common application of this device is the feeding of the electro-magnets excitation
coils which are installed in the vibrating system, linear and circular, usually employed as feeding
devices in automation systems.

All the feeders traditionally used supply the load with a fixed frequency depending on power
mains.

As we have to fit the springset to the feeding frequency we don’t have satisfactory
results.

To approach as soon as possible the resonance condition, the manufacturer of this feeding
system is obliged to do many adjustments on the springset supporting the container of the pieces to
feed.

This complicated operation seldom reaches the resonance condition1.

Using the vibrators power supply, to change the feeding frequency in order to reach the
resonance condition, it is sufficient to regulate the 4 rotating switches placed on the front panel.

Having the possibility to adjust the feeding frequency to the springset the improvements
reached are immediately verifiable.

As the regulation above mentioned can be made while the system is in motion, in a few
minutes you can find the best feeding frequency and obtain from the system the best performances.

This device proved utility also after the first installation because as the springset change its
elasticity on the time in consequence of the enervation of the material.

It is possible to keep unchanged the system performances by the years.

RESONANCE CONDITION: It is the frequency by which the feeding system delivers the minimum energy to
obtain the maximum vibration: The system is composed by the springset and the container of the products to be
feeded.

DEVICE DESCRIPTION

The vibrators power supply is very compact and easy to install.

With reference to the drawing at the bottom of this manual, it will be very simple to identify the
most important components.

Two holes (diam. 6 mm) will allow to fix the box to the structure which will support the device.

Electrical connections are made with a 6 and with a 9 poles terminal box (see wiring options
table at page 9).

The mains supply is protected with fuses inside the box.

The vibration frequency is selected with 4 rotating selectors (SW1) located on front panel (the

most left digit are hundreds of Hz, the second are tens, the third are units and the most right are

tenths of Hz).

The vibration intensity may be regulated with a potentiometer or through a voltage reference 0-

5V (the minimum and maximum limits of potentiometer may be regulated with trimmers MIN e

MAX accessible on front panel).

Overloads are limited electronically (by a circuit with autoreset) and are signaled from a red led.

The power supply is shipped with autostart on power-on (switch SW2 on front panel = up).
