Description

Frequency Inverters three-phase VFLC III 400V 4,5A (without housing)

The speed control by varying frequency and voltage is the best system for the control of induction motors.

Specifications:

• Input range: 400 Vac, 50-60Hz,  III
• Output:  +10Vdc
• Models: 3Kw (4,5 A)

Control:

• Input ON/OFF
• Input 0-10V  (remote control potentiometer TLR 017)
• Serial port RS-232   (telephonic connector for programming console)
• External terminal    (remote control potentiometer TLR 016)

Switching Parameters:

• Switch 1: Automatic / Manually  Restarting
• Switch 2: Freewheel stop or deceleration
• Switch 3: Not used
• Switch 4: V/F: Lineal / Quadratic

Adjustable Parameters by means of a programming console:

• Maximum output frequency (Fmax)
• Minimum output frequency (Fmin)
• The frequency of maximum voltage (FVmax)
• The frequency of minimum voltage (FVmin)
• The maximum output voltage (Vmax)
• The minimum output voltage (Vmin)
• Limit of output phase current (depending on model)
• PWM Switching frequency 3-16KHz
• Acceleration time (several steps)
• Deceleration time (several steps)
