SENSORLESS VECTOR
FREQUENCY CONVERTER
AFC200 type

0,37 - 3,0 kW

 


Main features:
  • Single-phase supply: 1x230V AC, 50/60 Hz
  • Output: 3x230 V, 0 .. 320 Hz, (0 .. 100 Hz for vector mode)
  • Switching frequency: 4/8/16 kHz, SVPWM modulator
  • Advanced control modes:
                   U/f (linear, square-law scalar),
                   Vector mode (sensorless)
  • 2 analog inputs 0(2)..10V, 0(4)..20mA
  • 1 analog output 0(4)..20mA
  • 6 fully separated digital inputs 0/(15..24)V
  • 2 relays (250V/1A AC) 
  • Communication port RS485 - ModBus RTU (9600/19200), remote control of unit operation and programming of all parameters of the frequency inverter 
  • Integrated PI regulator
  • 7 constant frequencies: operation with constant frequencies, switching through digital inputs 
  • Band frequency elimination 
  • High-contrast LED control panel 
  • Motopotentiometer functions
  • Programmable control structure (local/remote) 
  • Displayed parameters: output frequency, mechanical speed, reference frequency, heatsink temperature, DC link voltage 
  • Protection: undervoltage, overvoltage, overcurrent, short-circuit, from loosing RS485 communication
  • Build-in RFI filter
