2.英文详情介绍

EMOTRON FDU48-090 is a frequency converter designed specifically for variable torque loads such as fans and pumps in the FDU 2.0 series. It has a rated power of 45 kW and a rated current of 90 A. It is used for speed regulation and energy-saving control tasks in HVAC, water supply systems, and industrial fans.

Product Features:

Rated output of 45 kW/90 A, input voltage of 3 × 380-480 V, suitable for square torque loads such as fans and pumps.

Built in PID regulator and load monitoring function, can achieve constant pressure water supply, flow control, dry running, and belt breakage protection.

Support multi pump cascade control, can manage up to 4 pumps under standard configuration, and expand to 7 pumps after adding relay boards.

Standard EMC filter and DC reactor, protection level IP54, suitable for industrial site environment.

Equipped with sleep mode, automatic flushing function, and the ability to start the rotating motor, reducing the frequency of ineffective operation and maintenance.

Product application areas:

Building constant pressure water supply system.

HVAC circulating water pump.

Speed regulation of cooling tower fan.

Industrial boiler induced draft fan and blower.

Sewage treatment aeration fan.

Municipal drainage pump station.

Agricultural irrigation pump group control.

Secondary circulation pump for district heating.

Industrial cooling water circulation system.

Ventilation fans for tunnels and underground spaces.

Conclusion: Overall, FDU48-090 is characterized by a power level of 45 kW, built-in pump specific functions, and IP54 protection, making it suitable for multi pump parallel systems and fan speed regulation scenarios that require constant pressure or constant flow control. It is a practical choice for energy-saving operation and soft start stop of fan pump loads.
