  1. Radiation- and Magnet field- TolerantPower Supply System System Concept :Water-cooled Floating Power Supply Monitoring & remote control 19‘‘ Power Bin

  2. Modular Floating Power Supply • 8-12 independent potential free outputs, floating • Sensing of all outputs • DC output power 2,2kW at 250VDC per 3U box (depends on installed modules)

  3. Modular Floating Power Supply • CE conform EN 50 081/82 part 1 • Safety in accordance with EN 60 950 • Water cooled • Easy insertion / extraction locking lever and carrying handle

  4. Modular Floating Power Supply • Power box for 6 modules, single or dual output • Floating Range >10V (min. ca. 1,5 x Uout) • Up to 100mT Magnet field tolerant

  5. Radiation Tested Modules of PL 500

  6. Radiation Doses References

  7. Principle of Modular Structure

  8. Magnetic and Radiation Tolerant Power Module  Adjustable Values on the Regulator Board : • Output Voltage • Current Limit • max. Module Voltage (OVP) manual trimming

  9. Modular Control Board Basic Board with: • Clock Generation • Global Module Off if Mains Voltage too low • All Monitoring & Control Signals are fed to an (optional) plug-in monitoring board • (Already developed except the plug in board)

  10. Monitor and Control Board (simple) • One analog output for each voltage & current (2 * 12 lines + return) • Inhibit input for each channel (12 lines + return) • Connection to external control via 50-wire flat cable(i. g. to EMLB) (available)

  11. Monitoring Board (Medium Version) • Multiplexing of input / output signals (4 address lines, 1 enable line) • Voltage, Current, Temperature & Status (4 lines + return) • Inhibit input (1 line + return) • Connection to external control via 25-wire flat cable (Ready for board design)

  12. Monitoring Board (Complex Version) • Redundant micro controller system • Measurement of Voltage, Current, Temperature & Status • Inhibit & Switch Off of each channel possible (this feature must be activated with a jumper) • Connection to external control via 2-wire CAN-Bus (Component evaluation and testing Stage)

  13. Monitoring Board with ELMB integrated • connects all voltage, current, temperature and status signals to the CERN ELNB board • inhibit / switch off possible via ELNB outputs • Connection to external control via 2-wire ENLB can bus(possible solution, still to develop)

  14. Available modules: • Range 2-7V <30A/200W Dual Output Module • Range 5-12V <20A/200W Dual Output Module • Range 2-7V <100A/500W Single Output Module • Range 5-10V <70A/500W Single Output Module • Voltage trimmable +/-20%, intern manually

  15. CANbus & OPC serverworking with „Coplex Monitoring Board“ • Access to all monitoring information and control function • Can handle up to 126 Power Supplies with max. 8 channels 63 Power Supplies with more than 8 channels • One Address may use for “emergency” • Indicates each faulty detail

  17. Canbus Interfacefor Crate Remote Control CANbus Controller • Conforms CAN specification 2.0A (11-bits identifier) • 9-pin male DSUB connector (CiA DS102-1 Specification) • Opto-isolated transceiver , unshielded cable can be used with at least 110 nodes for high speed (1 Mbaud) bus Prepared by Institute of Nuclear Physics ; Cracow - POLAND

  18. Canbus Interfacefor Crate Remote Control Wiener CANbus Interface Protocol • COB ID mapping doesn’t directly correspond to the CAL/CMS priority definition • CANOpen protocol is not supported • No NMT, SDO, SYNC, TimeStamp, Nodeguard messages • It doesn’t conform Minimal Functionality Device Specification (CiA 301 profile) Prepared by Institute of Nuclear Physics ; Cracow - POLAND
