Emerson M-Series DC to DC System Power Supplies Product Description

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.
