GU-C40 and FGC4000BX-90DS (Note 6)
Note 1. In case of DC power supply which has no current control, please be careful that rush current (peak value 140A, width 2ms) flows at the turn on of power supply in 1m cable for power supply. 2. In case of DC power supply which has no current control, please be careful that rush current (peak value 140A, width 2ms) flows at the turn on of power supply in 1m cable for power supply. 3. Main current condition of GCT Thyristor is 1500Arms and duty 50%. 4. If input turn-on signal is shorter than ton (min) protection operates and turn on width is 28s min and 32s max. 5. If turn-on signal is input during toff (min) protection operates and turn off width is 44s min and 52s max. 6. If GU-C40 and FGC4000BX-90DS are used together, Rth (j-f) is becomes 0.012C/W. (Only FGC4000BX-90DS is used. Rth(j-f) becomes 0.011C/W)

Installation of GCT Thyristor
GCT Thyristor is put on the gate driver to coincide with the holes each other and covered by gate attachment at the ring gate of GCT Thyristor. By screwing at each hole, GCT Thyristor is installed on the gate driver.

Please twist the plus and minus power supply cables.
NOTE 1 Please prepare these parts beforehand. NOTE 2 A cross section of power supply cable is 0.75mm2 or 0.83mm2 and twist the plus and minus cable. The power supply cable is shorter than 2m and lower inductance.
