DC Electronic Loads
Modular, High-Current, & High-Voltage DC Electronic Loads
NH Research, Inc’s (NHR) line of DC Electronic Loads includes the Modular DC Load (4312, 4350), High-Current DC Load (4700), High-Voltage DC Load (4760), and the Bi-Directional DC Load (9200) series. NHR DC Loads are designed for ultimate configuration and flexibility. Each of the DC Electronic Loads has their own specific set of features suited for specific applications.
These DC Electronic Loads are designed for testing applications that require high-voltage plus a wide range of measurements such as consumer power devices, chargers, adapters, LED driver testing, solar panel testing, higher-power DC supplies, telecom rectifiers, fuel cells, batteries and much more!
Key Features:
- Ultimate configuration flexibility
- Precision voltage, current, power & timing measurements
- Constant Loads – CV, CC, CP, CR & in combination
- Simplifies automated test stand development
- Software tools to shorten test development time
- Built in features require fewer test devices
- Safety limits protect UUT
NHR DC Electronic Loads deliver the power, precision and flexibility needed to meet or exceed your test solution needs.
