Chroma’s C8000 test systems, software and fixtures will provide Power-One calibration and final testing for all production units potentially to UL1741 standards. Tests provided by these systems include EEPROM Read / Write, Calibration, Input Voltage Start (CH1), Input Voltage Start (CH2), Input Current (CH1), Input Current (CH2), Temperature Check, Connection Time, Re-Connection Time, Non-grid protection, Under-Voltage Protection, Fan Test, Clock Check, Ground Fault Check, Grid Connection, Energy Verification, Input Over-Range, and Efficiency. Power levels for the inverters will range from 3KW to 12KW with single phase, three phase, and split phase connections.

With its focus on Renewable Energy and “Green” power solutions, Power-One has recently established itself as the world’s second largest provider of solar inverters. Further, as one of the world’s ten largest providers of power conversion and power management solutions, Power-One is one of the few companies with the product breadth to support every step in the refinement of utility-grade AC into the various DC voltages required to power high-availability infrastructure systems at the site, system, and semiconductor levels.

Acquisition of the C8000 Systems will dramatically reduce future ATE downtime and production shortfalls for Power One. It will also greatly improve the future readiness, sustainability, and operational capabilities by providing an economical and expedient solution for obtaining test results in the final stage of production. Special software has been developed to integrate with Power-One’s shop floor quality system.

The C8000 is commercial-off-the-shelf equipment which has been in production for over 10 years at Chroma. Designed to be a complete solution to all types of power electronics testing, the C8000 system is integrated with a wide range of hardware such as AC/DC Sources, Electronic Loads, Multimeters, Oscilloscopes, Noise Analyzers, and Isolation/Dielectric testers. Its range of use, combined with an open architecture software platform, PowerPro III, provides users a flexible, powerful and cost-effective test system.
