Dynamic Braking unit Medium-voltage High-end heavy-load 220-280KW ,690V

Description of  Braking unit:

The GN series is to divert the regenerative energy which is produced in the process of decelerating the motor, into a braking unit, converting that energy into heat. Regenerative energy flows from the motor into the inverter DC bus, manifested as increased bus voltage.

Characteristic of this series:

Rated power: 55KW-500KW;
Rated braking current: ≤500A;
Chopper voltage range: DC1150V±5V(With a keyboard);
Voltage grade: 660V;
Minimum resistance value: 8.5~2.8Ω;
IP protection: IP00/IP23;
Terminal:M10;
ED: 20%-80%;
Vibration: 0.5g;
Temperature coefficient: ≤400ppm/℃.

Advantages of  Braking unit:

Safety:the tripping function against IGBT short circuit breakdown can avoid the fire caused by IGBT breakdown of resistor after overload running.
Wide compatibility:compatible with general resistance rather than non-inductive resistance if it is special design. Adjustable chopper voltage DC 630V-DC760V. Economical feature:high ratio of performance to the rensonable price.Effective and practical for braking circuits of inverter’s.


Installation of  Braking unit:

It adopts a book-shape design and can be installed in parallel connection with zero clearance. It is recommended that up to 3.
