Product Description

Bedford vector control inverter

B502 series inverter adopts DSP control system which supplies sensorless vector control(SVC) and V/F control. Comparing with V/F control, the performance of SDP has greater superiority, which consists of Built-in SVC and V/F control, it is widely aplied to high speed contro l accuracy, rapid torque response and high performance at low frequency.

Main Features:
* Control mode: Sensorless vector control, V/F control, Torque control
* Start-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.
. Mult-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 communication interface.
* Standard Modbus.
