The OAI is specifically designed to provide a good quality performance and functionality for very specific purposes. It has the ability to provide a full line of I-V testers which can be ordered as a single system or any of the TriSOL Solar Simulators. It is built with 3 standard ranges of testers including the 1A, 1to 5A and 10A. It is also made available with higher current testers for further variation on the device. The OAI application engineer ensures that the I-V Tester the user chooses is optimized for the user's application.
