Frequency Inverters 2.2 kW

The company 'Specialist' is the official distributor of Nietz brand 2.2 kW frequency inverters to Ukraine. We supply 10 different models that are capable of solving motor control tasks.

How to choose the best price-feature frequency inverter 2.2 kW?

The listed frequency inverters are suitable for motors with a power of 2200 W or less. If you have a more powerful motor, the next in the standard range are 3.7 kW inverters.

First of all, you can significantly narrow your choice by the number of phases and input voltage for power connection, as well as output — for single-phase or three-phase motor 220/380 V.

The next step is to determine whether scalar or vector control modes are required. The easiest to set up and relatively cheap are scalar frequency inverters 2.2 kW. They do not require entering all motor parameters to start work, but there are also limitations — they work well only with load types such as centrifugal pumps and fans, which do not require a high starting torque.

Vector frequency inverters 2.2 kW are capable of providing more efficient control due to the current vector calculation algorithm. They provide more precise speed maintenance. Compared to the all-purpose model AT20, the 2.2 kW inverters of the new FC2000 series are better due to the built-in EMC filter and higher carrier frequency, which ensures more efficient and smooth speed regulation.

An additional factor is the location of the inverter installation. Almost all Nietz models have a case with IP20 protection rating, designed for installation in a specialised control cabinet. If you need an inverter that will operate in a polluted air environment with possible splashes, choose the NZS series, which has IP65 protection.

In low-power 2.2 kW inverter models, external resistors are generally not required to dissipate heat when braking the motor, so their connection is not provided for.
