Power supply Three-phase voltage from 24V to 690V at the
various frequencies, depending on the type and series. For the power supply of
the vibrators it is possible to use electronic frequency drives or electromechanical
frequency converters. Conformity with Standards and Regulations Low Voltage
Directive 2014/35/UE; EN/IEC 60034-1; UL 1004-1, CSA C22.2 No.100, NEMA MG-1.
Operation Continuous service (S1) at the maximum declared centrifugal force and
electric power values. Centrifugal force Range extended up to 5300 kgf (52 kN)
with force output adjustable by varying weights position. Mechanical protection
IP 66 according to IEC/EN 60529. Protection against mechanical impacts IK 08
according to IEC/EN 62262. Insulation class Class F (155°C).

Tropicalization Standard on all vibrators, with vacuum
encapsulation up to size AF33 and for frame size AF70, with “drop by drop”
trickle system for sizes AF50 and AF68. (on request vacuum encapsulated winding
may be supplied for these two frame sizes). 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 heaters can be assembled on the lower sizes. Fixing of the
vibrator In all positions and therefore without restriction. Two different
types of connection 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 at start-up.
