Description

ACS880-607LC Liquid-cooled brake chopper units

A Brake unit is used for resistor braking. It handles the energy generated by decelerating motors for example in emergency stops. Whenever the voltage in the common DC bus exceeds a certain limit, a braking chopper connects the bus to a braking resistor. Offering includes a 1-phase brake unit and 3-phase dynamic brake unit (DBU) which utilizes R8i modules.

Two different braking concepts. The main difference between the concepts is controllability:

  1. One-phase brake chopper, on-off controlled (no modulation), brake current depends only on the resistance of the brake resistor. Compact and cost-efficient. Used mostly in single drives.
  2. Three-phase brake unit with modulating control. Brake current/power is controlled. Used mostly in multi drives.

Highlights

  • Compact
  • Easy installation
  • High instantaneous braking capability
  • Designed for both single drive configurations and common DC bus drives
  • The customized product that fulfills your needs
