We offer braking resistors from 1kW to over 2000kW, supporting voltages from 12V DC to 1200V AC. Whether you need a compact 50W aluminum housed unit for a servo drive or a 2000kW stainless steel grid resistor for a mining haul truck, our portfolio covers the spectrum.
· Stainless Steel Grid Resistors: Heavy-duty, open-air design with high pulse capability. Ideal for ports, mining, and high-inertia applications.
· Aluminum Housed Resistors: Compact, chassis-mountable units with excellent heat dissipation. Perfect for VFDs, elevators, and industrial machinery.
· Ceramic Wirewound Resistors: Cost-effective, axial or radial lead designs for smaller drives, HVAC systems, and test equipment.
· Liquid-Cooled Resistors: Ultra-quiet, high-density solutions for space-constrained or noise-sensitive environments.
· Forced Air Cooling: Integrated fans maintain optimal temperatures during continuous braking cycles.
· Natural Convection: Open-grid designs rely on passive airflow for simple, reliable operation.
· Liquid Cooling: Achieve exceptional power density in compact footprints, ideal for marine, wind turbine, and data center applications.
Our braking resistors incorporate thermal cut-offs, overload protection, and flame-retardant materials to ensure safe operation. IP-rated enclosures protect against dust, moisture, and corrosion, extending service life in harsh environments.
· Ports & Container Terminals: STS cranes, RTG cranes, and ship-to-shore equipment require high-peak-power resistors to handle frequent, high-inertia braking cycles.
· Mining & Heavy Industry: Haul trucks, excavators, and conveyor systems rely on rugged, vibration-resistant braking resistors for safe deceleration on steep grades.
· Industrial Automation: VFDs, servo drives, and CNC machines use it for controlled stopping, precise positioning, and energy management.
· Elevators & Lifts: Braking resistors dissipate regenerative energy during descent, ensuring smooth, reliable operation and passenger safety.
· Renewable Energy: Wind turbine pitch control and solar tracker drives use it for emergency stops and load management.
· Test & Simulation: Dynamometers and motor test benches employ braking resistors to simulate mechanical loads and absorb regenerative power.
As a certified manufacturer based in China, we maintain full control over design, material selection, production, and testing. Our factory-direct pricing eliminates intermediaries, ensuring competitive costs without compromising quality.
Our 7,000+ square meter facility is equipped with advanced winding machines, welding stations, and automated testing equipment. Every resistor undergoes 100% resistance verification, dielectric strength testing, and thermal validation before shipment.

Q: What is the difference between a braking resistor and a dynamic braking unit?
A: A braking resistor is the passive component that dissipates regenerative energy as heat. A dynamic braking unit (or chopper) is the electronic control module that switches the resistor into the DC bus when voltage exceeds a threshold. Many drives have built-in choppers; we supply the matching resistor.
Q: How do I calculate the required braking resistor power rating?
A: The power rating depends on motor power, deceleration time, and duty cycle. A common rule: the resistor should be rated for at least 10–20% of the motor’s kW rating for standard applications, with higher values for frequent or high-inertia loads. Our engineering team can assist with detailed calculations.
Q: Can a braking resistor be used for continuous duty?
A: Yes, but the duty cycle rating (ED) must be appropriate. For continuous braking applications (e.g., downhill conveyors), we offer resistors with 100% duty cycle and forced air or liquid cooling.
Q: What IP rating do I need for outdoor installation?
A: For outdoor or wash-down environments, we recommend IP54 or higher. IP56 provides protection against strong water jets and is suitable for ports, marine, and mining applications.
