Three-Phase Frequency Converter 3.7 Kw Series EL - DELTA

Three-phase 400V 3.7Kw (5CV)frequency inver ter, RFI filter and integrated programming panel.

The frequency converters allow the control and speed variation of standard three-phase motors.

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

On the front panel, 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 EL series of frequency converters of the brand DELTA incorporates:

• Potentiometer.
• 15 programmable speeds with activation by inputs.
• Possibility of PID control.
• RS485 communication.
• Integrated RFI filter.
• Programming panel integrated in the front panel (not remotizable).
• Supports control of communication cards.
• Braking module not included.
