High Power Metal Clad Braking Resistors, metal terminal connection, 600W-5000W

Construction:

  1. Insulation is applied through a high-temperature process.
  2. An aluminum encased consists of an alloy metal coil-type resistance element assembled into an aluminum enclosure.
  3. After high-temperature anodization, the enclosure is filled with a special non-flammable cement paste and hardening.
  4. Since this component is embedded in the heat-proof cement, it is not affected by external mechanical force, and dusty environments.

Features:

  1. Aluminum house, good heat dissipation.
  2. High Insulation alibility
  3. Widely used in inverter, elevator and UPS system.
