First question asked Welcome!

Hello,
We are looking to replace diodes for alternators within the creys power plant. The diode models we currently have in place are:
-IR45L100: rotating diode for direct conduction excitation
-IR45LR100: rotating diode for reverse conduction excitation
You provided us with these diodes, do you still produce them?
Regarding the alternator, it is a brushless rotating exciter: a small 6-pole alternator with induction and rotating armature.
The characteristics of the alternator are detailed below:
-Type: EDR 380/140
-rated power: 20.812 kVA
-nominal voltage: 122.1V
-Power factor: 1
-Frequency: 1Hz
-rated current: 98.4A
-Speed: 1000rpm
-degree of protection: IP23
-Constructive form: A4
-Department: S1
-Excitation voltage: 57.8V
-Excitation current: 5.74A
-Connection of the rotary rectifier: Graetz bridge
-Diode with direct polarity: IR 45 L 100
-Reverse polarity diode: IR 45 LR 100
For any questions, i am avalaible at +33 (0)7 83 67 22 29 or etienne-externe.bourcier@edf.fr
