The electrical panels with Inverter are designed to optimize the regulation of the motor rotation speed, significantly reducing energy consumption.
The frequency converter, called Inverter, is certainly the best solution for managing the three-phase asynchronous motor. It allows you to control the voltage by limiting the current, avoiding peaks and sudden mechanical stresses during the starting phase and allows you to adjust the frequency with variable values. In this way a maximum torque can be provided for each speed and current peaks can be avoided, protecting the mechanical parts from excessive torque values.
This type of starting can be applied to engines of any power.
Each panel has lights indicating the presence of voltage, thermal intervention and engine running, as well as the engine start and stop button and the mushroom-shaped emergency stop button.
The adjustment of the inverter speed, both manually and automatically, takes place via an Autel production tool positioned on the carpentry door (To Inv Reg or DPFREG-25, depending on the type of inverter chosen), which allows you to view the instantaneous frequency.
Everything is contained in a painted sheet metal box with wall fixing brackets, disconnect switch with door lock system for powering the panel and lock for closing the door.
Interfacing with the users is carried out via the terminal block positioned in the lower part of the panel, where, in addition to the terminals for powering the motor, also those for possible interfacing with a start/stop and stop button panel are made available. remote emergency.
The supply also includes the electrical diagrams, created in compliance with current regulations, and the Declaration of Conformity.
On request, various options can be integrated, including ammeter for displaying the absorbed current, hour counter for counting the motor's working hours and cable glands for the entry of the cables of the utilities to be managed, as well as various possibilities for customization , depending on the customer's needs.
