SPI - SMART PRIMARY INJECTION TEST SYSTEM

SPI - SMART PRIMARY INJECTION TEST SYSTEM

The SPI system is the FIRST high current test systems to permit a user to type in a predetermined current and the SPI system will generate and regulate the requested high current without preheating the test sample by pulsing the output current at high currents.

The SPI system also has the unique ability to turn on at the current zero crossing every time for any load by automatically adjust the output firing angle.
