PC series four quadrant frequency converter

The PC series four quadrant frequency converter is a perfect combination of control and energy saving developed by us, a real four quadrant running product. The IGB rectification technology under PWM control completes the bidirectional control of rectification and energy feedback, and the design is compact and professional. It is mainly used for the load of the potential energy, the load of the large inertia and so on.

Voltage level

380V level (three-phase power) 15-560kW
660V level (three-phase power) 18-630Kw
1140V level (three-phase power) 37-710kW

Product features
Application

The TI is the latest generation of DSP for high speed motor control, and the three core processing technology platform is innovated. Ultra high speed operation ensures that complex vector computation is fully realized.

The rectifier / feedback unit adopts the sine wave mode to automatically regenerate the electric energy to the grid, which is more energy efficient and environmental protection than the traditional braking unit + braking resistor braking mode.

The network side current harmonic is small, and the fundamental wave power factor is close to 1 (full load):

Excellent closed-loop vector control performance and zero torque achieving 200% torque output capability.

Aiming at the application design of the lifting industry. Power line logic control, brake control, pre excitation, overspeed protection, starting torque compensation and other functions to ensure lifting.

The safety and reliability of the industry;

Support standard RS485 communication:

The master slave control function meets the requirements of motor power balance and speed synchronization in multi motor transmission occasions.

The five speed control methods are: no PG vector control, PG vector control, V/F control mode, V/F separation control, direct torque control.

Rich peripheral interfaces;

Super protection function.
