Our principals designs and manufactures power electronics test instruments and complete turn-key test systems. Their  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. They have been in the power electronics test business for over 50 years and has fully equipped facilities in   California and Shenzhen, China.

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 Their test systems above. Because of that higher performance requirement, Their instrumentation generally has faster test execution times and more comprehensive measurements than single-function bench-top-type instrumentation.

Automatic Test Systems for Power Conversion & 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.


Fundamental to the success of all products is the total commitment to customer support. Their 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.
