NHR-9520 AC/DC Power Module
The NHR-9520 AC/DC power source by NH Research is a bi directional programmable unit that operates as a Source Load platform with regenerative DC capability. It supports precision energy control for automated test environments. The NHR-9520 allows hardware mode selection through software configuration. The output type AC or DC is selectable through software commands. Channel organization is configurable through the same programmable interface. This structure enables flexible system integration without physical rewiring. All commands within the power module are processed sequentially. The internal control system uses a FIFO first in first out queue. Commands are executed strictly in the order received.
The communication process with the NHR-9520 is established over TCP/IP. Any program capable of sending plain text can control the unit. The interface does not require proprietary hardware. The scripting languages including Python that can directly communicate with the hardware unit. Industrial controllers such as PLC or PLA devices are also supported by the module. In DC mode the AC/DC power module operates with voltage as the primary control parameter. The DC configuration functions as a bi directional power flow between 9520 and the UUT. Energy can flow from 9520 to UUT and from UUT to 9520. The regenerative operation eliminates the need for external dissipation loads. The direct current mode provides programmable voltage limit protection. Adjustable current limit control maintains safe operating conditions. Programmable power limit in watt units enforces defined boundaries to function independently for precise test configuration.
The NHR-9520 AC/DC power module has a default AC operation that is uni-directional with voltage and frequency control. The programming defines which Standard Event Status Register events can trigger a summary indication. The ESR command is used to read the event status information. Enabled events are allowed to set the Event Summary Bit which is bit 5 of the Status Byte register. The AC configuration includes programmable voltage limit functionality. Power limit configuration is selectable in watt or volt ampere units. User defined voltage wave-shapes are supported for advanced grid simulation. The NHR-9520 delivers controlled AC and DC energy management for advanced validation systems.
