Control signal
PRECAUTION
(1) Voltage compensate capacitors are expected to be located as close as possible to the Hybrid IC.
(2) Minimize the area of closed circuit of gate circuit so as not to be affected by induction noise.
(3) D1 requires approximately the same voltage of power modules.
(4) When recovery current flow in D1 , pin 30 is applied high voltage .
(5) When you make late speed of reverse bias at the time of short circuit protection operation,
(6) When the built in short-circuit protection circuit need not be used, please connect resistance of 4.7k ohm between pin 30 and 20.
O
I
In that case , counterplan for protection which insert a zener diode between pin21 and 30 are necessary like above diagram.
please adjust and connect a capacitor between pin 21 and 27.
(D1 and Dz1 are not required.)
