INVT CHE100 general purpose series frequency inverter adopts DSP control system which supplies sensorless vector control and V/f control. Market positioning focuses on the OEM clients at middle and low end market. The performance of CHE series is more perfect and stable. It is widely applied in Pump &Fan, some applications with high speed control accuracy, rapid torque response and high performance at low frequency.
- Control mode:Sensorless vector control, V/f control, torque controlStart-up torque: 0.5Hz/150% (SVC)
- Built-in breaking unit for 0.4kW to 11kW.
- If need to stop rapidly, please connect the brake resistance directly.
- Multi-step (8 steps) speed control: PID control; Traverse control
- Offer 4 multi-functional digital inputs,2 analog inputs,1 relay output,1 analog output,1 open-collector output.
- AVR: Can output constant voltage automatically when input voltage is fluctuating.
- Offer RS485 serial communication interface, Standard Modbus.
- External keypad: LED or LCD is optional.
