Power supply
Three-phase voltage from 24V to 690V at
the various frequencies, depending on
the type and series. It is advisable to use
the Vibravar, Multivar or the CFV variable
high frequency power suppliers to power
the electric vibrators.
Conformity to the European Directives
Low Voltage 2006/95/EC.
Reference standards
EN 60034-1.
Operation
Continuous service (S1) at the maximum
declared centrifugal force and electric
power values.
Centrifugal force
Range extended up to 5300 kgf (52kN)
with force output adjustable from 0 to
100%.
Mechanical protection
IP66 according to IEC 529, EN 60529; IK08
protection against impact.
Insulation class
Class F (155°C).
Tropicalization
Standard on all vibrators, with vacuum
encapsulation up to size AF33 and for fra-
me size AF70, with “drop by drop” trickle
system for sizes AF50 and AF68.
Ambient temperature
To operate correctly, from -20°C to +40°C.
Vibrator thermal protection
With PTC rated thermistor heat detectors
130°C installed as part of the standard
assembly size AF70 onwards.
Also on request thermistors with different
temperatures and anti-condensation hea-
ters can be assembled on the lower sizes.
Fixing of the vibrator
In all positions and therefore without
restriction. Two different types of con-
nection are available for the ITV-VR and
ITVAF series: fixed connection, where the
electric vibrators are connected to the
structure by bolts through fixing holes
and the RS cradle connection, where the
electric vibrators are connected to the
structure with the standardized cradle
type RS2 except for frame size AF10, for
this the cradle fixing is type RS1.
Lubrication
All the electric vibrators are correctly
lubricated in our factory and need no
further lubrication when used. Special
grease for high-speed operation is used
for frame sizes AF50, AF68 and AF70 a
periodic re-lubrication is recommended
by means of special grease nipples. The
excess grease is discharged into the
weight compartment by means of the
differentiated labyrinth system.
Terminal box
Generously sized to make the electrical
connections easier. Special shaped termi-
nals allow to fix the power supply cable.
Electric motor
Three-phase asynchronous type.
Casing
Specifically designed for high speed
duty. In high tensile strength aluminium
alloy for frame sizes AF10, AF30 and AF33.
In spheroidal cast iron for sizes
AF33 (600245), AF50, AF68 and AF70.
