Overview

The ABB 216NG63 Auxiliary Supply Unit is engineered to deliver stable, isolated 24 VDC power to automation modules and control racks in demanding industrial environments. It maintains consistent performance even under fluctuating DC input supply conditions, ensuring continuous operation for mission-critical systems.

Additionally, the 216NG63 supports parallel redundancy, enabling two units to operate simultaneously for fail-safe power delivery. Maintenance access is simplified through manual isolation, allowing service work without system shutdown. With its low ripple and noise design, the unit safeguards sensitive control electronics against voltage distortion and electromagnetic interference.

For example, in high-voltage substation automation, the 216NG63 powers protection IEDs and communication modules, maintaining operational integrity during grid disturbances or maintenance cycles.
