MITSUBISHI GATE COMMUTATED TURN-OFF THYRISTOR UNIT
GCU08AA-130
HIGH POWER INVERTER USE
PRESS PACK TYPE
Note 1. (1) Guaranteed power supply voltage for operation is 19V minimum and 21V maximum.
(2) When over voltage occurs, GDU voltage bus (G-K voltage for GCT) is clamped to be 21V if mamimum voltage for input gata voltage from power
supply is 25V and maximum duration of over voltage higher than 21V from power supply is 0.4 sec when control signal is on (Please see Fig. 8).
(3) When over voltage occurs, GDU voltage bus is clamped to be 21V with no time limitation if maximum voltage from power supply is 25V and control
signal is off (Please see Fig. 8).
Note 2. GCT is off state and no gate signal is supplied for gate driver. No leakage current flows between gate and cathode of GCT.
Note 3. Optic fiber data link HFBR-1521 and HFBR-2521 are interlocked each other.
