Unipolar Power SuppliesLarge, free standing supplies
Medium and small, rack mounted supplies
Each power supply has individual Bitbus controller integrated into power supply (or rack)
Dipole power supply has two controllers, one for the bulk supply and one for the chopper
Precision ADC digitizes two readbacks per second, 7 readbackstotal

MCOR30 Crate
Crates are Eurocard form-factor (not VME crates)
Crates and backplanes are identical to PEP MCOR crates
SPEAR has 8 30 A modules (PEP has 16 12 A modules)
Bulk supplies can not drive a total of 240 A, be aware(!).
CPU is a regular VME CPUadaptation done by “Frankenboard” sitting between CPU and backplane
Digital (serial) communication between Frankenboard and Candi modules, update rate is 4 kHz
CPU runs EPICS IOC, which gives direct access to power supplies from Ethernet
Second Ethernet interface will be used for 4 kHz feedback system updates

MCOR Racks
SPEAR3 Power Supply Controls 10
Special Hardware
• 1 MCOR30 supply feeds QMS switchyard (6 chassis), which selects 1 out of 94 quadrupole trims
• 4 Bitbus-controlled TSP supplies feed 5 TSP switchyards, which select 1 out of 16 (32) TSPs per power supply
• Kicker power supplies are integrated into kicker controls (Allen-Bradley)
SPEAR3 Power Supply Controls 11
RF System
The RF power supply is controlled through the LLRF control system.
