Highlights
Variable speed driver
A frequency converter is an electronic device used to control the rotational speed and torque of an electric motor. The motor, in turn, drives a load (such as a pump). A frequency converter converts the alternating current voltage of the network into direct current via a rectifier and is stabilized by the intermediate circuit capacitor bank. Finally, the inverter converts the voltage from direct current to alternating current with variable frequency again. Frequency converters for primary water and waste water treatment applications are equipped with several customized functions for controlling single and multipump systems.
Applications
MINIVAR electrical panels are optimal in various applications with:
• Submersible or surface pumps for irrigation (constant pressure and frequency modulation)
• Pumps for pressurization units (constant pressure and frequency modulation)
• Submersible or submersible pumps for drainage control (constant level and frequency modulation)
• Electric motors (frequency and speed modulation)
Components
The panel is made in an ABS thermoplastic box with an innovative Elentek design, with gasket and predisposition for wall fixing while maintaining the IP55 degree of protection of the panel.
An external multifunction display allows simple and immediate programming and the display of parameters and electrical data. The display and the front selectors allow you to manage the system and signals. Easy to install thanks to the connection and wiring diagrams included in the panel.
