Magnet Controls GroupOctober 4, Intermediate PS - Ethernet PS Controller (EPSC)

Magnet Controls GroupOctober 4, Intermediate PS - EPSC Purpose Replaces the PEP 2 Bitbus Power Supply Controller Provides commonality with the Bitbus Controller Performance better then the Bitbus Controller 20bit ADC 24bit DAC Equal to or less expensive then Bitbus Controller Rationale for Replacement Bitbus DAC obsolete - new DAC required Bitbus network obsolete - convert to Ethernet (10/100 Mb/sec over UDP) FPGAs at end of life and not good choices for new designs 8044 processor is obsolete Use standard +/-15VDC power supply

Magnet Controls GroupOctober 4, Intermediate PS - EPSC Functions Precision current regulation Readback of current, voltage, and ground current Ground fault detection and protection Hardware magnet and power supply protection Fault latching and reporting Simple low cost serial communication to central control Control of power supplies of many ratings, types and from different vendors Standard cables (Cat 5 UTP and D-sub computer cables)

Magnet Controls GroupOctober 4, The MCOR Systems Power 6A, 12A, and 30A correctors, small quadrupoles, and trim magnets that require unipolar or bipolar current MCOR6 - 40V, 6A, 240W MCOR V, 12A, 480W MCOR30 – 40V, 30A, 1,200W

Magnet Controls GroupOctober 4, The MCOR6 and MCOR12

Magnet Controls GroupOctober 4, The MCOR30

Magnet Controls GroupOctober 4, MCOR Systems - PLC Uses Uses SPEAR 3 experienced MCOR30 bridge MOSFET failures during bulk power supply turn on – need PLC for soft-start MCORs not provided with ground fault detection. A PLC with external circuitry is needed MCORs power some magnets that are water-cooled. MCORs are not provided with a Klixon or water flow switch interface. A PLC is needed Provides bulk power supply remote turn-on and turn-off Provides bulk power supply output voltage and current monitoring
