## Radiation- and Magnet field- TolerantPower Supply System

_**System Concept :**_Water-cooled  Floating Power Supply
- Monitoring & remote control
- 19‘‘ Power Bin

## 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)

## 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

## 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

## Principle of Modular Structure

## Magnetic and Radiation Tolerant Power Module 

**Adjustable Values on the Regulator Board :**
- Output Voltage
- Current Limit
- max. Module Voltage (OVP)
- 		manual trimming

## 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)

## 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)

## 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)

## 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)

## 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)

## 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

## CANbus & OPC serverworking 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

## Canbus Interface for Crate Remote Control

## Canbus Interface for 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

## Canbus Interface for 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)

## Custom OPC Server

**Features:**
- Supports only one type of devices (i.E. WIENER only)
- Is dedicated to one type of PCI CAN I/F card (API library) – presently **Kvaser Card**
- Needs to be redesigned if one of above changes
