Dynamic Braking unit Light-load 50A,30kw

Dynamic Braking unit Light-load 50A,30kw

The LN 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: 7.5KW-150KW
Rated braking current: ≤200A
Chopper voltage range: DC660V±5V(Jump line)
Voltage grade: 400V
Minimum resistance value: 20~3.8Ω
IP protection: IP00/IP23
ED: 20%-80%
Vibration: 0.5g
Temperature coefficient: ≤400ppm/℃

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


Applicable to various low-voltage inverters.
