About NH Research…
|
|
NH Research (NHR) designs and manufactures diagnostic test equipment
used to functionally test several types of electronic power devices
such as power supplies, converters, telecom rectifiers,chargers, adapters,
inverters and UPSs. For automotive HEV/EV applications,
NHR builds test equipment for batteries, auxillary power modules
and chargers. NHR test equipment consists of both power instruments
such as AC and DC programmable loads as
well as automated test systems
controlled
through a full featured test executive on a PC. Applications include
production test, engineering characterization, agency certification
qualification, and depot repair. Located in Irvine, California,
Shenzhen and Suzhou, China,
NH
Research has been in the power electronics test equipment business
for over 30 years. |

Programmable AC and DC Electronic Loads
A complete line of modular and high-power loads originally developed to meet
the exacting requirements of test system integrators is available for
use either in a PC-controlled test system or as a manually-controlled
bench-top instrument.
All loads incorporate a built-in waveform digitizer that yields an unprecedented
18 different dynamic measurements from a single capture. In addition,
a new touch-panel graphic control interface on certain models provides
both expanded instrument control
functionality and display of test waveforms.

Automatic Test Systems (ATE)
This group of products consists of PC-controlled, load-intensive test systems
that feature a powerful test executive to get the customer up and testing in
a minimum amount of time…often just a few hours. For instance, power supply
manufacturers will use the emPower® test
executive that includes a comprehensive library of power supply test
routines. Each test routine needs only entry of the pass-fail limits to complete
a full
test step. In this manner, the test engineer is often able to create
a complete test program without having to write any code. |
Worldwide Support
NHR test equipment is usually an essential final step in a customer’s production
lines or laboratory, thus load and system reliability along with responsive
support are absolutely critical. To ensure this capability, NHR is fully
staffed with the
technical resources, diagnostic tools and replacement parts necessary
to resolve problems anywhere in the world. This support system includes
knowledgeable application engineers backed up by the actual product designers, regularly
scheduled factory training programs, calibration services and on-line
support. |
NHR’s commitment is to provide advanced test capability together with the
fastest test execution times to ensure world-class competitiveness
for its customers. |
