1ata Bulletin8000HO046410/2004North Andover, MA USAMODICON® QUANTUM 140CPS11420 SUMMABLE ACPOWER SUPPLYGeneral DescriptionThe Quantum 140CPS11420 Summable AC Power Supply providespower to the system backplane while protecting the system from noiseand nominal voltage swings. All Quantum power supplies feature overcurrent and under voltage protection. In the event of an unforeseenloss of power, the Quantum power supplies ensure that the system hasadequate time for a safe and orderly shutdown.Wiring examples(refer to user guide for important safety information):This diagram is valid for both 115VAC and 230 VAC source voltages.1234567Power loss alarmInstall jumper for115 VAC operation.AC LineAC NeutralThe 140CPS11420 power supply converts the incoming power sourceto a regulated +5VDC to support the CPU, the local I/O andcommunication option modules mounted in the backplane. Powerbetween the field sensors and the Quantum I/O points is not providedby these power supply modules.A summable power supply such as the 140CPS11420 can operate ineither Standalone mode or Summable mode. Whenever two summablepower supplies (must be the same model) are combined in the samebackplane, they automatically operate in summable mode delivering20A of power to the back plane.The Quantum power supply can be inserted into any backplane slot.However, for best heat dissipation and maximum life it is recommendedthat the power supply/s be inserted in the outside slot/s.As an option, modules can be ordered with a conformal coating appliedto protect the internal circuitry from corrosive gases such as Chlorine,Nitric Oxide, Hydrogen Sulfide and Sulfur Dioxide.140CPS 114 20AC Power SupplyPwr ok*A removable terminal strip allows for easy maintenance.Removable terminal strip is included.Visual status and diagnostic information isavailable on the face of the module as LED’s.Pwr ok Green Power is supplied to the bus140XTSStandard, Screw Type, 40 pointsOptional rack accessories are ordered separately.140XCP50000140XCP51000Dummy module without terminal blockDummy module with cover
