NH Research designs and manufactures power electronics test instruments and complete turn-key test systems. Its products are used worldwide by manufacturers in the switching DC power supply, UPS, battery and battery charger industries. Applications typically involve either characterization or final test of customer products where a combination of advanced measurements, rapid test times and ease of setup & use are important. NH Research has been in the power electronics test business for over 40 years and has fully equipped facilities in Irvine, California and Shenzhen, China.
Automatic Test Systems for Power Conversion and Energy Storage Products:
The first type of test system consists of test solutions for the functional testing of DC power supplies, UPSs and similar power conversion components. Applications include high volume production testing, engineering design characterization, incoming inspection and depot repair. The newest series of this type of test system provides for simultaneous testing of up to 16 units in a single pass.
The second type of test system consists of a complete test solution for electrified vehicle batteries that require power cycling or simulated drive cycle profiles to determine long term performance. In addition, the test systems are used for testing battery chargers through a battery emulation mode of use. All such test systems are flexibly configured with medium-to-high-power capability and typically used by vehicle manufacturers, battery & battery charger manufacturers, independent battery test laboratories, university engineering laboratories and certifying agencies.
Power Instrumentation for Customer-Built Test Systems:
This group of products consists of programmable AC & DC sources and loads for use in a customer designed & built test systems. All instruments were originally designed to optimize the performance of the NHR test systems above. Because of that higher performance requirement, NH Research instrumentation generally has faster test execution times and more comprehensive measurements than single-function bench-top-type instrumentation.
Fundamental to the success of all products is the total commitment to customer support. Both NH Research facilities are fully staffed with the technical expertise, diagnostic tools and replacement parts to resolve problems rapidly whatever the cause. This support system includes knowledgeable application engineers, a broad network of field engineers, factory training programs, test program developers, calibration services, telephonic and on-line support.
