Panel-mount frequency inverter FR-A741

IP20compact

Featuring a large number of innovative technologies, this compact frequency inverter delivers exceptional performance and is ideal for hoist drives and high-powered machines with torque that can be used for regenerative braking. This includes a wide range of applications with vertical and horizontal movements such as conveyor systems, centri- fugal separators, testing machines, winding machines and so on. The FR-A741 both reduces your initial investment outlay and keeps operating costs low. The integrated power regeneration function makes it possible to use smaller and much less expensive drive systems and enables simpler and more compact switchgear cabinet layouts. Cutting energy consumption and protecting the environment are now key issues in mechanical and plant engineering. Drive motors usually account for most of the power used and they also take up lots of space and require special cooling facilities. The FR-A741’s regenerative braking system makes it much more efficient than conventional drive systems, giving it the potential for significant energy savings. The integration of the frequency inverter and power regeneration system in a single unit reduces space requirements, making installation in the switchgear cabinet much simpler. The combination of the integrated AC reactor and no need for an external braking unit eliminate a large amount of additional wiring. These inverters need up to 60 % less main circuit wiring and occupy up to 40 % less space than conventional solutions, depending on the output capacity. The result is significantly less overall cable lengths and switchgear cabinet space requirements.
