Three-phase frequency converter 0.75 Kw vector series E - DELTA

Three-phase frequency converter 400V 0.75Kw (1CV), RFI filter and integrated programming panel.

Frequency converters allow control and speed variation of standard three-phase motors

This model of frequency converter already has a built-in RFI filter suitable for the CE market, to avoid electromagnetic interference that could occur with other electronic components.

On the front button, it incorporates all the necessary buttons for motor control and a potentiometer for speed regulation. it can also be controlled from pushbuttons and external potentiometer. The front button (control panel) is removable, that is, it can be separated from the frequency converter, and by cable (not included in the supply) fix it on a keypad. The supply includes the scheduling panel.

The frequency converter includes PLC (automaton) function, you can use the inputs and outputs of frequency converter. There are letters of extension of inputs and outputs.

The series of EL frequency converters of the DELTA brand incorporates:

• Vector control (sensorless).
• Potentiometer.
• 15 Programmable speeds with activation by inputs.
• possibility of PID control.
• RS485 communication.
• Integrated RFI filter.
• Remotizable programming panel.
• Built-in automaton.
• Supports control of communication letters and inputs/outputs.
• Includes braking module.
