Emotron FDU - AC drives

Secure the flow and save energy


Emotron FDU 2.0 AC drive optimizes the operation of your pumps, fans, compressors and blowers. Your process is protected from damage and downtime, and you will benefit from reduced installation, energy and maintenance costs.



Protection from damage and downtime


Soft starts and stops protect your equipment. Reduced start currents result in smaller fuses, cables and energy bills. Controlled stops eliminate the risk of water hammer and other costly damage.


A built-in shaft power monitor and a unique Load Curve Protection function protect your process by immediately detecting any situation that could cause inefficiency or damage. Early warnings and safety stops allow preventive action.



Energy savings and optimized operation


Emotron FDU regulates flow and pressure by continuously adapting motor speed. No energy wasted and no unnecessary equipment wear. A sleep function further reduces energy consumption by pausing the motor when it is not needed to be run. An automatic pump rinsing function increases efficiency.


Multiple pump or compressor control is a reliable and cost-efficient method of keeping a constant flow or pressure despite varying demands. Emotron FDU controls up to seven drives.



User-friendly and reliable operation


Operation parameters can be set in your own process units – m3/min, bar, Pascal etc. – making monitoring easier and more reliable. The removable control panel has a copy function for transferring settings to other Emotron FDU units. You can switch between local and remote control by the push of a key on the control panel. The virtual connection of logical functions, comparators and timers means no cables or external I/Os are required.



Available in IP20/21 and IP54 versions


Emotron FDU is available in IP20/21and IP54 versions. The robust steel construction in IP54 version means that you can install your AC drive close to the application, which saves the cost of cabinets and long motor cables.The 300-1,500 A units (IP20 modules) is also available in compact CG-designed IP54 cabinets. IP20/21 series 25-244 A are optimised for mounting in control cabinets (IP20) or on electrical room wall (IP21). Robus and compact design, easy access to power terminals. Extended temperature range up to 55 °C.



Simplified maintenance


Should a process problem occur a full status report will be generated. You can quickly identify the cause and take corrective measures. Maintenance is simplified thanks to a minimum of easy accessible mechanical parts and fold-out power modules.
