Frequency Inverter Elentek Minivar

MINIVAR is a range of compact control panels designed for the control and protection of 1 electric pump with frequency inverter.

The electrical panel is fitted inside a thermoplastic box in ABS featuring an innovative design by Elentek, with unibody seal and special provisions for wall-fixture maintaining the protection rating of the electrical panel.

An external multifunction display enables simple and immediate programming and display of parameters and electrical data.

The display and front selectors enable system management and signals. Easy to install thanks to the wiring diagrams and connection diagrams inserted in the panel.

Applications:

• Borehole or surface pumps for irrigation (constant pressure and frequency modulation)
• Booster pumps (constant pressure and frequency modulation)
• Borehole or submersible pumps for drain control (constant level and frequency modulation)
• Electric motors (frequency and speed modulation)
