Frequency Inverters

Technical characteristics:

- Rated operating voltage: 230/400V АС; 50 Hz
- Tolerance of the operating voltage:±10%
- Maximum output power: 0.75-15.0 kW
- Unbalance of phases: < 3%
- Frequency fluctuation: < 5%
- Output frequency: 0 - 400 Hz
- Output voltage: from 0 to Uвх. max
- Overload capacity:
    constant: up to 110%

     momentary: up to 150%
- Accuracy of the output frequncy adjustment: 0.1%
- Output discrete control signal 24V
- Output analogue control signal: 0-10V
- Sliding compensation: from 0 to 20%
- Ambient temperature : -10°÷60ºС
- Maximum altitude: 2000m
  
 

Mounting:
- to a flat surface using screws
- mounting position – vertical with maximum incline up to ± 5º. When more than one inverter is mounted in a board it is recommendable to mount them next to each other, and when this is not possible, proper cooling of devices should be provided.

 

Advantages:

-  DC - brake in static mode
- Dynamic breaking with external breaking resistor – used in inert electric motor load 
- Output voltage setting option 
- Option for activation of output safety functions
- Rotation speed increase – automatic and manual 
- Adjustment of the V/F control curve – linear or quadratic 
- Omission of resonance frequencies
- JOG function 
- ‘counter’ function  
- Automatic restart option in case of power supply failure 
- 15- speed degrees control option 
- Selection of control from the control panel; external or COM terminal 
- Frequency control from the control panel, external potentiometer by current or by voltage 
- Input signals on clockwise or counter-clockwise rotation, multi-step control, restart, etc.
- Function extending option: by including of additional modules

 

Functions:
Control of three phase inductive motors with a short circuited rotor 

 

Applications:
Industry-conveyors, packing and lifting machines, mixers, pumps, compressors
