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 28
s min and 32
s max.
5. If turn-on signal is input during toff (min) protection operates and turn off width is 44
s min and 52
s max.
6. If GU-C40 and FGC4000BX-90DS are used together, Rth (j-f) is becomes 0.012
C/W.
(Only FGC4000BX-90DS is used. R

CONNECTION INSTRUCTION FOR THE GATE DRIVER
Connection instruction for the gate driver refer to Fig. 1.
OUTLINE DRAWING
Refer to Fig. 2
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 in-
stalled on the gate driver.
NOTE 1
Please prepare these parts beforehand.
NOTE 2
A cross section of power supply cable is 0.75mm
2
or 0.83mm
2
and
twist the plus and minus cable.
The power supply cable is shorter than 2m and lower inductance.
