Parameter-duplication stick Brake chopper integrated аnd series ELM 1000 frequency inverters provide the so-called no-sensor control, V/f control, and impulse control while the output load can reach up to 150% within 60 seconds.

It features easy definition of curves and easy parameters setting of the inverter through the use of control panel buttons. The inverter can auto-calibrate according to the motor power, i.e. if the inverter is connected to a motor with power different from that set by the inverter manufacturer, it automatically adjusts its programmable parameters to suit the motor parameters.

You can find also additional devices: LCD remote frame size keypad for cabinet; cable for remote keypad and parameter copy stick.

What is an inverter and what does it do

An inverter is a key component for electricity management in industrial settings. Frequency inverters are designed to control three-phase induction motors with short-circuited rotor. They provide for the implementation of some control laws, thus becoming an indispensable part of the control systems for conveyors and packaging machines, pumps, air conditioning systems, etc.

Unlike frequency inverters, there are inverters that are widely used to convert DC electricity to AC electricity, which is most commonly used in industrial conditions, such as energy from a power source, such as a battery or several other types of DC energy.

There is also an application that is commonly seen in solar panel systems which require that the electricity from the panels be fed into a battery bank for later use. Once the electricity is required, it is run from the battery, through the frequency inverter, and into the power grid of the property.

In this way, it is possible for AC-operated machines and electronics to operate with their nominal electrical energy, without worrying about de-synch occurring in their motors or moving components.

The goal of the converter is to change the direction and overall frequency of the electrical current which is passing through it. This happens through a carefully engineered process, which we’ve concealed out of sight, as to add an extra layer of safety.

Ease of installation

The frequency inverters must be mounted on a flat surface with bolts. Mounting position – vertically.

When more than one inverter is mounted in a board, it is recommendable to mount them side by side and when this is not possible, the appropriate cooling conditions should be provided. We advise you to use the services of a professional electrician when dealing with frequency inverters or other electronics.
