Power Converter Characteristics
|NR31-03 + ND31-04
|3 ~ 400V/1775A x2
|Front end VME
Power Converter Architecture
SM1 magnet is located on M2 beam line inside PPE221 zone.
SM1 power converter architecture
SM1 magnet is supplied by the NR31-03 power converter mounted in serie with the diode module ND31-04.
The diode ND31-04 is not installed nearby the NR31-03 and some changes were implementded in the power circuit of the NR31-03
Control & Regulation Part
The bending magnets B4 and B5 of M2 beam line needs to be interlocked with SM1 and SM2 spectrometers.
To manage this functionality, the power converters of B4, B5, SM1 and SM2 are interconnected.
For SM1, an electronic card called "Interlock B4/B5 M2" has been added in the supply crate of the NR31-03.
The regulation part is standard.
A current rate limiter card is installed in the converter crate.
Magnet protection is standard.
Magnet connection is standard.
