1.3.4 Regulatory Compliance Testing
As governments and regulatory bodies expand enforcement of product quality standards, regulatory
compliance testing has become a requirement for manufacturers. The Sequoia/Tahoe Series is designed
to meet AC source requirements for use in compliance testing such as IEC 61000-3-2, 3-3, 3-11, 3-12, to
name a few. Tight integration with Virtual Panels software facilitates easy generation of test sequence for
various safety, compliance and EMI tests, as per various UL, IEC, IEEE standards, and national electric
grid code of conduct/compatibility.
1.3.5 Electric Vehicle (EVSE, V2G) Testing (only for Sequoia Series)
With the vast expansion of EV infrastructure, the inter-compatibility between various vendors' equipment
is a key to success. This can be ensured only by testing the charging infrastructure compliance to
standards. While the Sequoia Series grid simulator mode can help simulate various grid conditions from
strong grid to weak grid, its electronic load mode can help emulate the car’s On-Board battery charger
load. With 85% of power recovery efficiency, the Sequoia Series not only helps by saving electricity, but
also minimizing heat emissions inside the lab. What’s more, the DC source mode and AC sink mode
operations of the Sequoia Series make it ready for the bidirectional Vehicle-to-Grid testing.
1.3.6 Manufacturing Line Testers
The Sequoia/Tahoe Series are a good fit for end of production line functional testers, as they offer many
benefits for test developers, operators, and quality team. The automatic paralleling option helps to scale-
up / scale-down the power capacities, dynamically, to safeguard the investment on infrastructure. Full
support for SCPI commands, availability of NI LabVIEW drivers, and IVI Drivers, helps test automation
developers to choose their comfortable development environment. Load dependent variable fans help
reduce the acoustic noise and improve occupational health.
