8000HO0465 10/2004 Data Bulletin North Andover, MA USA MODICON® QUANTUM™ 140CPS12420 REDUNDANT AC POWER SUPPLY General Description The Quantum 140CPS12420 Redundant AC Power Supply provides power to the system backplane while protecting the system from noise and nominal voltage swings. All Quantum power supplies feature over current and under voltage protection. In the event of an unforeseen loss of power, the Quantum power supplies ensure that the system has adequate time for a safe and orderly shutdown. The 140CPS12420 power supply converts the incoming power source to a regulated +5VDC to support the CPU, the local I/O and Wiring examples communication option modules mounted in the backplane. Power (refer to user guide for important safety information): between the field sensors and the Quantum I/O points is not provided by these power supply modules. This diagram is valid for both 115 VAC and 230 VAC source voltages. A redundant power supply such as the 140CPS12420 can operate in either Standalone mode or Redundant mode. For high-availability applications, two redundant power supplies can be used in the same 1 backplane. In the event one supply fails, the other maintains the Power loss alarm necessary power so that the backplane processing and active 2 communications are not affected. 3 Install jumper for Quantum power supplies can be inserted into any backplane slot. 115 VAC operation. 4 However, for best heat dissipation and maximum life it is recommended AC Line that they be inserted in the outside slots. 5 AC Neutral 6 As an option, modules can be ordered with a conformal coating applied to protect the internal circuitry from corrosive gases such as Chlorine, 7 Nitric Oxide, Hydrogen Sulfide and Sulfur Dioxide. 140 CPS 124 20 AC Power Supply Pwr ok Backplanes are ordered separately.
