To complete type number replace "xx" by the required nominal input
voltage, e.g. 24 IPW3-05-T.

Double outputs should have symmetrical load conditions to comply
with the specifications listed on the left side.
Extended temperature range -S is available for all types.
Replace -T by -S on type number, e.g. 48 IPW3-05-12-S.
Modifications and customs are available upon request.
Important: All units require (an) external coupling capacitor(s) Cio = 270 pF / 1.5 kVDC
Single output: -Gi (pin 23,24) to -Go (pin 12)
Double output: -Gi (pin 23,24) to Go (pin 10,11)
Dual output:
-Gi (pin 23,24) to -Go1 (pin 9) and -Gi (pin 23,24) to -Go2 (pin 16)
