c 700.00 1600 175.00 2000 215.00 4. Fast Switching High Power Thyristor Type FT 500 AW, AX and AY. These units rated at 400 A average on-state current and from 600 to 1300 V peak repetitive are del%gQed for dv/dt of 200 V/psec and a di/dt of 200 A/psec. The turn-off time for the fastest unit, AY, is 15 psec, while the shortest turn-off time for the best Westinghouse unit, 2782 series rated at 300 A, is 40 psec. 5. Logic Triac type BCR 150 A features high blocking voltages 400 to 1200 V, 150 A rms on-state current and 20 V/vsec commutating dv/dt at high di/dt. This unit is similar to the International Rectifier 100 A and the 200 A triacs. The difference is the price. For a 1000 V repetitive peak off-state voltage such asI for example, is required for 480 V 3$1 line -3- TM-164 0810 operation, the price comparison is as follows: Current(W) 100 $278.00 150 $105.29 200 $
