Description

1KW Metal Clad Dynamic Braking Resistor for AC Drives and Inverters

This 1KW dynamic braking resistor features a durable aluminum housing and chassis mount structure, ideal for motor drive systems and industrial inverters. It ensures rapid energy dissipation during braking, enhancing system safety and performance.

Key Features

  • Power rating: 1KW
  • Metal clad aluminum housing for efficient heat dissipation
  • Chassis mount design for stable installation
  • High surge handling and long service life
  • Available in custom resistance values

Typical Applications

  • VFDs (Variable Frequency Drives)
  • Industrial motor control
  • Elevator and crane systems
  • Energy braking in automated machinery

Advanced Build for Heat and Safety

Our brake resistors are built for durability, safety, and efficient energy conversion during motor braking.

  • Core Structure: Made from high-temperature and insulating materials for long-term reliability under demanding conditions.

  • Lead Wires: Feature a double-layer protection design (grid braided + TPE coating) to resist light, heat, moisture, chemicals, and physical damage — ensuring safe and stable performance.

  • Aluminum Shell: Designed with precision-cut heat dissipation grooves. These channels guide hot air away quickly, improving cooling efficiency during operation.

  • Braided Wire & Tight Packaging: High-temp resistant and neat in appearance, offering overload protection and stable performance even in harsh environments.
