Version Name	Description	Functions included / excluded	Tracking	Quantity
Demo	Electrical demo board, to validate the topology and control strategy defined, EMC signatures. PCB can be internally routed if very simple, and if judged more efficient.	Power and regulation. Control (logic) or being controlled by a FGC controller is not required at this level.	PCB: EDMS Unit: ---	01
Prototype	Power Converter Prototype created to validate the functional technical specification, regarding electrical performances, control. The converter must be controllable by a FGC controller.	Converter cards and power elements must be located inside a mechanical frame, representing the final converter. PCBs are done through CERN service.	PCB: EDA Unit: ---	[01;02]
Rad / Elec Pre-Serie	Power Converters created to validate the work (quality, process, test) of the external companies before proceeding with the full series. Pre-series = Series most of the time, or with very few differences, considered as negligeable. The pre-series are tested at CERN using generic templates which will be applied to series. Pre-Serie, if modification are jugded too heavy, must be reworked to be identical to series.	All function included.	PCB: EDA Unit: EPC.db	[10;20]
Serie	Power Converter final version.	All function included.	PCB: EDA Unit: EPC.db	[op + sp]

Version definition

(2017-12-19) HL-LHC Meeting:
- Yves + Jean Paul + Miguel + Samer + Hugues + Vicente: HL-LHC2kA meeting.
  - During this meeting (2kA oriented), the case of one R2E-HL-LHC60A with a crowbar handling up to [4; 5] kA pk was discussed. indico.
  - It was decided that since this converter was only used some hours per year, the DCCTs would be placed inside the converter, not controlling purely the magnet load, to protect them from high peak current and to avoid over design.
