FDU Series

Secure the flow and save energy

Emotron FDU AC drive has been developed to control flow and pressure. It offers efficient and reliable operation of pumps, fans and compressors, reducing energy and maintenance costs. The series covers powers of up to 3,000 kW.

Available in both IP54 certified enclosure as well as IP20/21.

  • CG-Emotron Makes FDU Series IP 20,IP21 and IP 54
  • Rating : 11KW to 3000Kw
  • Sensorless Vector Control Drives
  • Overload 120% for 60Sec. For Every 10Minutes

Protection from damage and downtime

Smooth 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 load monitor and a unique Load Curve Protection function protect your process by immediately detecting any situation that could cause inefficiency or damage. These early warnings and safety stops for over- and underloads allow preventive action.

Energy savings and optimised operation

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.

User-friendly and reliable operation

Operation parameters can be set in your own process units – m3/min, bar, Pascal, Celsius 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 with the push of a button on the control panel. The built- in programmable logical functions, comparators and timers means that, in many cases, external PLC or relays can be avoided.

Available in IP20/21 and IP54 versions

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.

Simplified maintenance

Should a process or drive problem occur, a full status report will be generated for each event in fault logger. You can quickly identify the cause and take corrective measures. Maintenance is simplified thanks to a minimum of easy accessible mechanical parts and by using fold-out power modules in bigger powers.

Options add functionality

A number of options let you customise the functionality of the Emotron FDU 2.0 and fully utilise the product according to your needs. Up to four different options can be combined.

Multiple pump or compressor control

Up to three I/O boards can be connected for multiple control of up to seven pumps or compressors without PLCs or other equipment.

Communication

Communication options include fieldbus communication via Profibus and DeviceNet, Industrial Ethernet communication via Modbus/TCP, EtherCAT, Ethernet-IP and Profinet, and serial communication via RS232 or RS485 with Modbus RTU.

Motor protection

PTC and PT100 sensors can be connected to control motor temperature and give process feedback without using a transmitter.Safe stop This option board offers protection from unexpected start during mechanical maintenance, in accordance to the standards IEC 62061 SIL2 and ISO 13849. No contactor is required.

Liquid cooling

Units from 90 A can be provided with liquid cooling. This allows you to reduce operating and maintenance costs, and the cabinet can have a protection class higher than IP54.

EMC protection

A 1st environment category 2 EMC filter is available as a factory-mounted option.

Reduced harmonic distortions

A 12-pulse rectifier offers cost-efficient reduction of harmonic current distortions. It reduces power losses in equipment such as transformers and conductors, and eliminates the need to over-dimension these components.

Standby supply

This option makes it possible to supply the control circuits via an external 24 V AC/DC supply to maintain communication and set up the system when 3-phase mains are not connected. It also provides communication backup if 3-phase main power supply fails.

IP21 Top cover

If units are wall mounted in electrical room, a top cover drip protection is available for IP 20 units 11-160 kW.
