IP 54 OR IP 20, FREQUENCY-CONTROL WITH
AUTOMATIC DETECTION OF THE RESONANT
FREQUENCY
Frequency converters in the REOVIB MFS 268 series for vibratory conveyor technology offer the option of operating the vibratory conveyor at an optimal vibration frequency for the material – completely independently of the frequency of the electrical mains supply.
It is moreover possible, thanks to the system patented by REO, to determine the resonant frequency of the vibratory system automatically and to regulate the vibration amplitude to constant values. In addition, various sensor and valve logic links can be programmed. Devices can optionally be equipped with field bus interfaces, and are also available as versions with UL/CSA certification.
Devices in the REOVIB MFS 268 series are available with a max. output current of 3A, 6A and 8A as IP20 versions for installation in switch cabinets, and also as IP54 case designs.
Unique Selling Point
