د.إ8,888.00

GE DS2020ACHAG2 is a Regenerative Chopper Board for the General Electric AC2000 Drive Series.

⚡ Role and Function

A regenerative chopper circuit’s primary function in a Variable Frequency Drive (VFD) system is to manage regenerative energy.

  • Regenerative Energy: When a motor is being slowed down or decelerated, it acts like a generator, feeding electrical energy back into the drive’s DC bus. This is common in high-inertia applications like elevators, cranes, or centrifuges.
  • Preventing Overvoltage: Without a mechanism to handle this energy, the voltage on the DC bus would quickly rise, potentially causing an overvoltage trip and damage to the drive.

  • Regenerative Energy: When a motor is being slowed down or decelerated, it acts like a generator, feeding electrical energy back into the drive’s DC bus. This is common in high-inertia applications like elevators, cranes, or centrifuges.
  • Preventing Overvoltage: Without a mechanism to handle this energy, the voltage on the DC bus would quickly rise, potentially causing an overvoltage trip and damage to the drive.
  • Chopper Function: The regenerative chopper board senses this rising DC bus voltage. When the voltage exceeds a safe threshold, the board switches on a power resistor (an external braking resistor) to dissipate the excess energy as heat, thus maintaining the DC bus voltage within its operational limits.
