Power supply Three-phase voltage from 220V to 690V, 50Hz or 60Hz; variable frequency (in presence of PTC thermistor) from 20Hz to the base frequency with constant torque load profile tipo PWM. Polarity 2, 4, 6 and 8 poles. Conformity with Standards and Regulations ATEX Directive 2014/34/UE; EN/IEC 60079-0, EN/IEC 60079-7, EN/IEC 60079-31, EN/IEC 60034-1. Controls The components that affect protection are 100% accurately controlled and recorded. Functioning Continual service (S1) at maximum declared centrifugal force and electric power. Centrifugal force Range extended up to 11160 kgf. (109 kN), adjustable in a continuous linear mode with variation of the position of the eccentric weights. 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 AF 33 and 35, with “drop by drop” trickle system for larger sizes. Ambient temperature From -20°C to +40°C, on request it is possible to have vibrators for max. ambient temperatures of +55°C. Vibrator thermal protection Standard PTC rated thermistor heat detectors 130°C from size 70, on request for smaller sizes. On request, thermistors with different temperatures and anti-condensation heaters. Fixing of the vibrator In all positions and therefore without restriction. Lubrication All vibrators are lubricated in the factory and do not require further lubrication at start-up. Terminal box Large terminal box to facilitate electrical connection. Special shaped terminals allow for the power supply cable to be secured, whilst protecting it from loosening. Electric motor Three-phase asynchronous type. Designed for maximum starting torques and torque curves specific to requirements of vibrating machines.
