About This Unit

This master powerbank serves as the primary control and coordination module within the NHR 4600 AC Load platform. It contains the system‑level control electronics responsible for managing communication, load sequencing, measurement functions, and synchronized operation across multiple auxiliary powerbanks. In a full cabinet configuration, the master enables programmable AC load profiles, high‑accuracy measurement, and scalable power expansion for inverter, UPS, and power‑electronics testing. This unit was removed from a matched 4600‑series cabinet at Oak Ridge National Laboratory and is suitable for refurbishers, integrators, or users needing a replacement master controller for an existing NHR 4600 AC load system.
