Emotron FDU regulates flow and pressure by continuously adapting motor speed. Therer is no wasted energy and no unnecessary wear on equipment. A sleep function further reduces energy consumption by pausing the motor when it is not. An automatic pump rinsing function also 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. Emotron FDU is available in IP20/21and IP54 versions. The robust steel construction in IP54 version allows you to 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) are 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 walls (IP21). Emotron FDU has a robust and compact design, with easy access to power terminals and an extended temperature range up to 55 °C.
