Khushi Control System is a reliable Supplier of Dynamic Braking Resistor in Gujarat.
Khushi Control System was Founded In 2010 in Ahmedabad, Gujarat, India.
We are a Manufacturer, Exporter and Supplier of AC Drive / VFD, Soft Starter, Dynamic Breaking Resistor, and AC Drive Repairing Services.
Khushi Control System is a brand partner of Lauritz Knudsen and Inovance, we also sales INVT VFD.
Among its flagship products is the Dynamic Braking Resistor, a high‑wattage resistive unit engineered to absorb surplus energy generated during motor deceleration in VFD systems.
These resistors convert unwanted electrical energy into heat, safeguarding motor drives and reducing wear. Typical applications include cranes, conveyors, elevators, pumps, and industrial drives.
Khushi Control System enjoys a strong reputation for quality, precision, affordability, and timely delivery.
What Does a Dynamic Braking Resistor Do?
• Energy absorption during braking: When a motor slows, it behaves like a generator, returning power to the drive’s DC link. Without a path to dissipate this, overvoltage may occur.
The dynamic braking resistor shunts this energy and safely dissipates it as heat.
• Faster, controlled stopping: It enables smooth and rapid deceleration without relying on mechanical brakes that suffer wear and tear.
• Protection from overvoltage: Prevents drive tripping or damage by controlling voltage spikes during braking.

FAQs
Q1: What is a dynamic braking resistor?
A high power resistor that converts excess braking energy into heat to prevent overvoltage during motor deceleration.
Q2: How does dynamic braking differ from regenerative braking?
Dynamic (rheostatic) braking dissipates energy as heat, while regenerative sends it back into the grid. Khushi specializes in the former, ideal where grid feedback isn’t feasible.
Q3: How to select the right resistor?
Choose based on motor/DC link voltage, load inertia, braking duty cycle (<10%), resistor power rating, ohmic value, and cooling needs.
Q4: Can DBRs burn out?
Yes—due to undersizing, wrong threshold settings (<10% duty cycle), poor quality, or improper installation. Khushi offers design support and high quality materials to avoid these issues.
Q5: What maintenance is required?
Minimal—just keep them clean and ensure proper heat dissipation. Periodic checks on connections and insulation are recommended.
