0-120 V , 8kw , 200A.

The NH Research 9210-4912 is a high-performance, single-channel battery test system designed for advanced energy storage and electric vehicle (EV) testing applications. It supports both charging and discharging operations with bi-directional power flow, enabling full cycle testing without the need for external equipment.

With a voltage range of 0–120 V and current capabilities up to ±200 A, the 9210-4912 delivers 8 kW of power in charging mode and up to 12 kW in discharge mode. It offers rapid transitions between operating states and modes — including constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR) — making it ideal for dynamic simulations and complex test protocols.

Its built-in touch-screen interface allows users to easily configure tests, visualize real-time data, and automate sequences. The system supports return-to-grid functionality, maximizing energy efficiency by feeding excess discharge power back to the AC mains. Whether you're testing lithium-ion battery packs, modules, or custom storage systems, the 9210-4912 provides the precision, flexibility, and safety needed in today's fast-evolving battery research landscape.
