Aerospace, Avionics & Defense

dc power supply engineering character design verify test system model 5700Aerospace, avionics and defense industries require testing at high standards because the consequences of a product failure are severe. NH Research, Inc. (NHR) can help you achieve these standards by providing high quality, precise and reliable products.

This highest level of functional test is economically feasible with the turnkey 5700 Engineering Characterization Test System. Not only is the hardware capable of comprehensive testing but the programming and report formatting together make this system ready to deliver outstanding results immediately.

Within the defense ATE community, NHR also excels in its modular DC loads and sources. The Modular Test System S400 Series and  Modular DC Electronic Loads 4300 Series are meeting the high performance requirements and limited space restrictions of several major defense ATE programs today.

Charger & Adapter Test

dc power supply multi channel test system s650 seriesCharger and adapter testing demands hyper-fast testing to stay competitive and ahead of the competition. Testing a few units at a time simply isn’t competitive anymore. NHR enables the capability to test up to 16 units at once with the Model 600 Test System. The Model 600 has the smallest form factor in the industry, providing easy integration into a conveyor-based production line.

Energy Storage Testing

high power battery charge discharge test system 9200 seriesNH Research, Inc. (NHR), is a worldwide supplier of industry leading Energy Storage Testing Solutions. We provide instruments and systems to test batteries, fuel-cells, super capacitors, and similar energy storage devices as well as the electronic systems which use these accumulators including chargers, electric-vehicle (EV) power, battery management systems (BMS), critical power systems (UPS), Energy Storage Systems (ESS), grid-tied inverters, and more. Customers look to NHR for superior performance, ease of use, faster slew rates to match today and tomorrow’s technology, reduced testing time, improved safety, and energy savings. Our instruments and test systems use a modular approach to meet today’s energy storage testing requirements while being flexible and expandable for the future.

EV/HEV & Traction Battery Testing

high power battery charge discharge test system 9200 seriesNHR has two types of test equipment for EV/HEV & Traction Battery Testing.The Model 9200 Battery Test System consists of bi-directional, regenerative DC power modules with voltages of 40, 120 or 600V and is capable of charge/discharge and cycle testing of 10 – 250kW module and pack-level batteries. This highly flexible system can be integrated into an existing software environment, run from a PC with NHR’s Enerchron® Test Manager or locally through a touch-panel located on the 9200 cabinet.

The High-Current DC Electronic Load (120V) 4700 Series and High-Voltage DC Electronic Load (600V) 4760 Series air-cooled dc loads can be used in applications where only discharge is needed. These loads can be controlled either through LabVIEW or NHR’s Enerchron® Test Manager.

EV Powertrain Testing

ev powertrain testing - battery test system 9200 seriesEV Powertrain Testing can be done with NHR’s Battery Emulation Testing line which includes the High Power Battery Test System (9200) and the High-Voltage Battery Test System (9300) series. NHR’s Battery Emulation products are designed to emulate a battery rather than using a real battery. The emulated battery dramatically reduces testing time, provides highly repeatable test results, and creates a safer test environment. Also, preparation time, operator errors, and result variations due to battery temperature or aging, are eliminated.

Industrial Battery Charger Testing

high voltage dc load 4760 seriesBattery charger testing is transformed through  battery emulation in place of real batteries. Using real batteries for testing may introduce errors due to variables such as discharge state, temperature and age.

Battery emulation provides the advantages of more consistent and accurate test results while increasing test throughput.

One NHR solution with capability up to 48 kW, utilizes a combination of a Model 4700/4760 DC Load along with a programmable DC source to emulate a battery. Another NHR solution, with capability up to 72 kW, uses the 9200 Battery Test System with its bidirectional loads in a battery emulation mode.

PV/DG Grid Tied Inverter Testing

regenerative grid simulator model 9410
NH Research, Inc. (NHR) provides test equipment for  Solar PV/DG Grid Tied Inverter Testing which can simulate the utility connection as well as energy storage devices. The 9410 Grid Simulator can provide a 1Φ, 2Φ, or 3Φ simulated utility connection while allowing per-phase controls for amplitude, wave shape and the relative to a phase angle relationship. These features allow testing of any number of AC conditions including phase imbalance (in voltage and/or phase angle relationship), voltage sag, frequency changes, & harmonic injection. The included measurement system eliminates the need for additional power meters, DMMs, oscilloscopes, or spectrum analyzers.The 9200 Battery Test System includes a charge, a discharge and  state of the art battery emulation mode which allows for both testing of a real battery or electronically-emulating a battery. Battery emulation replaces the need to use a real battery thereby eliminating risks associated with a battery failure even those caused by a unit-under-test (UUT) failure. Additionally, battery emulation dramatically reduces testing time, provides highly repeatable test results, and creates a safer test environment. Eliminate operator error and environmental variables such as battery temperature or aging, to achieve precise results.
