  7. VERSION USED HVPS-1 - HVPS-2 - HK - PDM-Board Interface Synoptic : 1st flight version 28V (S) BAT_RET (P) 1 GND_28V (S) 3.3V (S) 28V_BAT (P) 2 GND_3.3V (S) D-Sub 9 F D-Sub 9M D-SUB 25 F D-SUB 25 M 6 C-W 3 C-W 3 ON/OFF 3 0-2.44V 6 x 14 HV lines 3 STATUS 4 SWITCHCOMMANDS 3 x 14 HV lines HVPS-2 HVPS-1 CS_DAC CS_DAC MOSI 6 SCK 3 MOSI 0-2.44V 6 DAC 3 DAC CS_OUT SCK CS_IO 9 6 bidirectional signals ON/OFF I/O expanders MOSI MISO 9 6 status signals D-Sub 9M SCK STATUS D-Sub 9 F Interrupt 4 SWITCHCOMMANDS MOSI MISO SCK Interrupt 2 2 2 2 2 2 2 2 2 2 2 differential transmitters GND_M 4 differential receivers 4 differential receivers GND_M BATTERY 24 wires D-Sub 15 F 4 Differential signals (LVDS) ( x2 = 8 wires)between PDM_Board and HVPS-1 6 Differential signals (LVDS) ( x2 = 18 wires)between HK and HVPS-1 D-Sub 15 M Micro-D 9 M D-Sub 15 M D-Sub 15 F Micro-D 9 F HVPS-1 would have DC/DC converters to isolate the powers GND_M HK PDM_Board 4 differential transmitters 2 differential receivers 4 differential transmitters

  8. Full PDM and potential areas for HVPS • 2 possibilities for HVPS: • 20 x 115 mm2 • 29 x 53 mm2 After discussions withJaceks, APC group and Pierre  27 x 53 mm2 chosed

  9. Reminder of the cables/interfaces/connections 9 lines toward PDM board (9 micro-D) 28 V + gnd battery (9 D-SUB) HVPS2 HVPS1 15 lines toward HK (15 D-SUB) 14 x 3 HV cables 14 x 6 HV cables 25 lines (25 D-SUB)

  10. 3D view of the HPVS D-SUB 25 F To HVPS-2 D-SUB 15 F To HK D-SUB 9 F To Battery 159 mm 159 mm Micro-D 9 M To PDM_Board HVPS-1 53 mm D-SUB 25 M To HVPS-1 HVPS-2 53 mm 14 * 3 HV cables 27 mm 27 mm 14 * 6 HV cables NB: 159 mm and 53 mm are the maximum available Better if it is less than that to fit more easily.

  11. Fixation with 2 plates Plate used to fixe the HVPS to the mechanical structure on the side. Top view

  12. Lateralview ~56 mm ~56 mm ~53 mm Fixation of the HVPS To the fixation plate Fixation to the Back part of the PDM mechanical Structure. ~27 mm ZONE where to put the holes for the cables ZONE where to put the holes for the cables ~120 mm Fixation plate ~120 mm

  13. Other possible zones for cables ~56 mm ~56 mm ZONE where to put the holes for the cables ZONE where to put the holes for the cables If HVPSs don’t lay directly on the fixation plate like bellow ~53 mm ~27 mm ZONE where to put the holes for the cables ZONE where to put the holes for the cables ~120 mm ~120 mm

  14. Another (better) option: The plate could have half height and be fixed to the mechanical structure with 6 screws. ~56 mm ~56 mm ZONE where to put the holes for the cables ZONE where to put the holes for the cables ~53 mm ~60 mm OR ZONE where to put the holes for the cables
