About DeltaV™ System Power Supplies

Power supplies – systems can’t operate without them.DeltaV™ System Power Supplies provide you with the most efficient and reliable power solutions available.

DeltaV power supply kits provide power to the system electronics and to the field. This is all the power you need for your DeltaV system.

Benefits

DC/DC system power supplies are plug-and-play components. They fit any power carrier, including horizontal 2-width and vertical 4-width carriers.

These carriers contain an internal power bus that connects to the controller and I/O interfaces, eliminating the need for external wiring. The carriers are easily mounted on T-shaped DIN rails!

Flexible and cost-effective, DeltaV DC/DC system power supplies accept 12V DC and 24V DC input power.

Modular construction and load-sharing capabilities of the power supplies allow you to add more power to your system or provide power redundancy.

Safety. Your I/O is always accurate because I/O subsystems and controllers are always supplied with stable, accurate 12V DC or 5V DC power. Power supplies are EMC- and CSA-compliant; notification is immediate in the event of a power failure; and system and field power supplies are completely isolated.

Simplified system power supply. System power supplies provide more www.abb-drive.com current on the 12 VDC I/O interface power bus, eliminating the need for 24 to 12 VDC bulk power supplies. All controller and I/O power is now available from the factory 24 VDC bulk power supply.

Product Description

The DC/DC System Power Supply is used to power DeltaV controllers and I/O interfaces from a 12 or 24V DC bulk power supply that can be mounted next to the controller in the power supply/controller carrier and provides the 5 and 3.3V DC power required by the controller.

It provides 5V and 3.3V DC power for the controller. It also provides 12 VDC power for the I/O interfaces and up to 8 amps when powered from a 24 VDC bulk power supply.

Plug and Play Components. The system power supply assembly fits into any power slot of any DeltaV power supply/controller carrier. This not only simplifies system design, but also reduces spare parts inventory through interchangeability.

DIN-Rail Mounting. Power supply installation is simple.

Mount the power supply/controller carrier on the T-shaped DIN rail. Then plug the system power supply into the carrier.

Internal Power Bus. The power supply/controller carrier contains an internal power bus. You do not need to use external cables to connect the system power supply to the DeltaV controller and I/O interface carriers.

Modular power supplies. You know the power requirements for today, but what about the future? Build a solid foundation now and build on it later. Modular power architecture allows you to install additional power supplies for controllers and I/O subsystems.

Precision outputs. System power supplies accept a wide range of power inputs and convert the inputs into precise power outputs.

Power Redundancy: DeltaV system power supplies can be redundant on a 1-to-N basis, while other systems are 1-to-1.

This provides an economical solution for creating system redundancy.

Fault Detection. Undervoltage and overvoltage conditions are detected and logged to protect the controller and I/O subsystems and to automatically cold-start the controller in the event of a high-capacity power failure.

Standards compliance. The power supply is EMC and CSA compliant. It is designed to comply with European ‘Power Factor Correction’ standards.

Immediate notification of power failure. The internal relay outputs change state and alert the user if the input voltage fails or the system power fails. In addition, an LED on the power supply housing

displays the status of the power supply.

System and Field Power Isolation. The system power supply provides isolation between the system power supply and the field power supply when the system power supply and the field power supply are powered by the same 24-volt DC bulk power system.

Power Supply Removal. The system power supply is easy to remove/replace. The bulk power cord connects to an easy-to-install connector instead of screw terminals.
