ABB RDCU-12C 3AUA0000036521

This is the heart of the system’s DC power distribution.

• Product Type: RDCU-12C – Rectifier/DC Unit.

• Function: This is an active front-end rectifier unit. It converts incoming 3-phase AC power (mains supply) into a stable, regulated DC voltage.

• Key Characteristics:

  • It creates a common DC bus for the entire system.

  • 12C likely indicates a specific current rating (e.g., 1200A). This high current rating shows it’s for a powerful industrial system.

  • It often provides clean power input with low harmonics, which is beneficial for the electrical network.

  • It can allow for regenerative braking, where braking energy from the motors is fed back to the DC bus instead of being wasted as heat.

• Order Code: 3AUA0000036521 – This is the unique ABB reference number for this specific variant of the RDCU unit.

In simple terms: The RDCU-12C is like a central, high-quality “power station” that provides DC power to all the individual motor drives connected to it.
