Emerson Ovation ™ Power system (5X00785G09)



Emerson Ovation ™ Power system (5X00785G09)

Basic Overview

Ovation ™ The power system is a DIN rail mounted power supply developed by Emerson, which integrates four modular fanless power supply systems designed for Ovation ™ The controller and I/O module provide reliable and stable power supply. The system adopts redundant configuration, with each configuration having independent external wide range AC or DC input power supply. It supplies power to each controller chassis and related I/O modules through dual diode bus 24 VDC output, and supports wetting power supply for circuit and I/O module contacts. If necessary, it can also provide 48 VDC auxiliary power supply.

The system provides two independent output schemes, namely "24 VDC/10 A/240 W main power supply+24 VDC/10 A/240 W auxiliary power supply" and "24 VDC/20 A/480 W main power supply+24 VDC/20 A/480 W auxiliary power supply", which can be flexibly selected according to actual power requirements.

Core Features

Redundancy and reliability design: Adopting redundant power supply configuration, the main power supply and auxiliary power supply are independently separated in the main and backup configurations; By using diode combiner power supply, the power supply is ensured to be continuously available, avoiding single point failures that may cause system power outages.

Wide range input capability: Supports dual input (AC and DC), with AC input voltage range of 85-264 VAC (frequency 43-67 Hz) and DC input voltage range of 90-375 VDC, suitable for power supply needs in different scenarios while reducing spare parts inventory.

High efficiency and low loss: The power efficiency is high (typical efficiency of 10A module>90%, efficiency of 20A module>92%), and it has active power factor correction function. The power factor can be optimized to 0.92 or above, reducing power consumption; Fanless modular design reduces the risk of heat dissipation failures and extends the service life of equipment.

Convenient maintenance and installation: The power supply supports hot swapping and can be replaced online, reducing downtime; Adopting a backplane design with pre installed DIN rails, it facilitates the installation of power distribution modules, circuit breakers, and power modules, enabling rapid deployment and reducing production losses.

Comprehensive monitoring and protection: equipped with continuous system monitoring function, visually displaying the operating status through three status LEDs (input, output, alarm); Provide multiple protections such as overvoltage, short circuit, overload, and open circuit, in compliance with IP20 protection level (IEC60529) and Class 1 protection level (IEC536), to ensure equipment safety.
