Frequency inverters are used to perform the task that involves the conversion of "invert" direct current (DC) frequency to alternating current (AC) frequency. A three-phase motor is driven by the means of "re-targeted" voltage. Before choosing this device, be sure to consider the following facts: such as, how it will be used, the electrical standards of the building, power capacity, power quality and energy efficiency. In other words, these devices are used to maintain a uniform quality of electric drive. And hence, it has become vital for the productivity and durability of electric drive. Selecting the right frequency inverter for an off-grid installation may be challenging, but the job gets easier when you choose inverters according to the right criteria.
General features of a frequency inverter:
This device will generate an alternating current (AC) that can be adjusted both in amplitude and frequency.
Different types of these inverters are available based on the area of application. It does help the engines to withstand strong speed and torque alterations without even getting damaged.
Usually, these inverters may be stocked with an automatism and self-regulating ramps, so that the start-up procedure are very simple. These inverters are very easy to use and are operated very easily through their default settings.
Besides the power connectors, all these inverters are equipped with the analogue and digital inputs and outputs and an optional RS485 interface. All you need is to click on the "start" button and that's it, this inverter will start working.
The control panel of this inverter could be removed and the desired value guideline could be determined with the aid of a rotary controller.
The typical applications of this device include: usage with the pumps and fans, used as a drive in various industries including textile industry, packaging fabrics industry. This device is also used in extraction technology, gym machines, advertising media, factory gates and so on.
Its display is so significant that it enables a good overview over the engine parameters; for example, it gives the dual presentation of speed as well as the power.
The other features of this device include the adjusting potentiometer, easy configuration, local test of the AC-drive, live-plot of measurement data, interface configuration, communication namely USB and RS 485 and many more.
This device has the capacity to manage difficult start conditions by start or stop ramps and is well equipped with up to eight digital and three analogue inputs and up to four digital and two analogue outputs. Due its automatic detection function, the device is very comfortable to determine the required parameters. As an end-note, these inverters are very useful to control the rotational speed of an alternating current (AC) electric motor.
