Products Description
High Power Braking Resistor is a core energy‑dissipating component for variable‑frequency servo systems. It is designed to dissipate regenerative energy during equipment emergency stops and deceleration, effectively preventing system over‑voltage alarms and burnout of key components. Covering multiple mainstream structural configurations, the product satisfies installation and heat‑dissipation requirements for diverse industrial scenarios. Delivering stable and reliable performance, it offers dependable braking protection for all types of power‑transmission equipment and is widely deployed across industrial automation, lifting & transportation and other industries.
Product Advantages
High Load‑bearing Capacity
It can sustain high‑load operation over extended periods, fits industrial conditions with frequent start‑stop cycles, and resists performance degradation.
Strong Impact Resistance
It withstands instantaneous high‑current surges and resists damage during sudden‑braking events, greatly lowering equipment failure risks.
Excellent Heat Dissipation
An optimized heat‑dissipation structural design delivers uniform, efficient heat conduction, allowing stable operation even in high‑temperature surroundings.
Broad Compatibility
It works seamlessly with most mainstream variable‑frequency and servo devices, supporting quick commissioning without complex debugging.
Working Principle
When equipment decelerates or is driven by external forces, the motor enters generator mode and generates large amounts of regenerative electrical energy.
This energy raises the frequency converter's DC bus voltage. Once the voltage hits the preset threshold, the braking circuit activates automatically.
High Power Braking Resistor connects into the circuit, efficiently converting regenerative electrical energy into heat for outward dissipation and rapidly consuming excess energy.
As energy continues to dissipate, the bus voltage gradually drops and the braking circuit deactivates automatically. This cycle repeats until the equipment comes to a smooth standstill.
A closed‑loop regulatory mechanism runs throughout the whole process to prevent component damage caused by over‑voltage and ensure safe operation of the entire power system.
Application Scope
Machine‑tool Processing Sector
Suited for spindle emergency stops on various CNC machining centers, it enables fast, stable braking without disrupting processing cycles.
Lifting and Transportation Sector
Used for tower cranes, hoists and lifts, it stably dissipates energy under heavy‑duty start‑stop conditions and prevents unintended load‑drifting risks.
Conveying‑equipment Sector
Applied to continuously operating machinery such as belt conveyors, it delivers smooth, controllable deceleration and minimizes material shifting and spillage.
New‑energy Testing Sector
Compatible with generator and power‑system test benches, it acts as an adjustable load for diverse braking‑performance validation tests.

Precautions
Reserve adequate heat‑dissipation space during installation. Do not stack debris nearby to block airflow, otherwise heat cannot dissipate in a timely manner.
Long‑term operation beyond rated working‑condition limits is prohibited. Operating in excess of the product's load capacity will drastically shorten service life and may create safety hazards.
Strictly separate main circuits from signal circuits during wiring. Incorrect wiring may trigger short‑circuits and damage adjacent matching components.
The housing reaches high temperatures during operation. Direct bare‑hand contact is forbidden to prevent thermal burns to operators.
Do not deploy the product directly in unprotected environments containing strongly corrosive gases or heavy conductive dust; such conditions will accelerate component degradation.
FAQ
Q: Does High Power Braking Resistor produce loud noise during operation?
A: It generates no extra noise under normal operating conditions. Only forced‑cooling variants produce very low fan‑running noise.
Q: Does High Power Braking Resistor require frequent maintenance?
A: Frequent maintenance is not required under normal operating conditions. Regular cleaning of surface dust supports long‑term stable operation.
Q: Can it be used outdoors?
A: Models with corresponding protection ratings are suitable for outdoor applications. Please inform us of your operating environment in advance so we can match you with an appropriate product solution.
