i550 protec

The award-winning i550 protec frequency inverter uses the same tried-and-tested technology used in our control cabinet inverters. It only differs in terms of a higher degree of housing protection and an adapted design. If there is not enough space in the control cabinet or the inverter has to be mounted close to the motor in various machine modules, then this versatile and reliable device is the right solution. Thanks to the extension box, a disconnect switch and operating elements can be used.
The requirements of the Ecodesign Directive, Standard EN IEC 61800-9-2, are met.
Application areas: Conveyor drives, traveling drives, winding drives, hoist drives, extruders, packaging machines, pumps, fans, ...
