Frequency Inverters 5.5 kW

In our online store, we offer 5 different models of frequency converters for 5.5 kW motors manufactured by Nietz. Our company, "Specialist", is an official representative of the manufacturer, and our cooperation has been ongoing for over 3 years. During this time, more than 6000 frequency converters from this brand have been installed at our clients' companies, performing well in operation. Our advantages include affordable prices for frequency converters at 5.5 kW, consultations from qualified engineers, warranty and post-warranty service and repair.

Our warehouse is located in the Dnipropetrovsk region, so if the product is available, you can purchase a frequency inverter 5.5 kW with fast delivery to a Nova Poshta branch or directly to a business in Kyiv, Bila Tserkva, Dnipro, Kharkiv, Odesa, Lviv, Zaporizhzia or other cities in Ukraine.

How to choose the optimal option for function and price for a frequency inverter 5.5 kW?

All 5.5 kW frequency converters (5500 W) are designed for 380 V three-phase motors of medium power, but they have different characteristics and functions. The choice of a specific model should be based on the operating conditions of the electric drive — control requirements, nature of load, method of connection to the industrial network, installation site, etc.

The NZ2200 series are 5.5 kW frequency converters with transition from 220 V to 380 V, which can be connected to a single-phase network for 220 V power and have a block for voltage boost at the motor output to three phases with a linear voltage of 380 V. This model is popular in garage conditions and small enterprises where there is no 3-phase source for connecting common 5.5 kW 220/380 V motors such as AIR100 and others.

The NLP1000 model is a budget frequency converter with power 5.5 kW. They implement a simple scalar control mode for electric motors, making them easy to set up without needing to input all motor parameters. However, they perform well only with a constant load without inertia. For example, with fans and pumps.

Regarding control method, the NZS is also a scalar frequency inverter 5.5 kW, but with IP65 protection. Unlike other models that require installation in a protective cabinet, the NZS model has a dust and waterproof housing and a sealed cable, enabling them to operate in places with contaminated air and withstand water splashes. This is one of the best solutions for pumping stations.

AT20 is a vector frequency converter 5.5 kW. Its vector current control algorithm is more precise than scalar, enabling it to work with variable loads, such as conveyors moving heavy goods over long distances, professional concrete mixers, etc.

The most expensive is the NZ8400 line, which has greater computational power and calculation speed thanks to a better processor than AT20.

If you are selecting a frequency inverter for a small crane with a 5.5 kW engine, it's better to consider a more powerful inverter CV20 for 7.5 kW. Although you can use AT20 for crane control, it lacks the useful function of stopping and holding loads, which is specialized for crane inverters.
