The model suffix "G01" represents the standard hardware version, which is compatible with the full specification cabinets and control units of Ovation 1D series. It is widely used in key process industries such as thermal power, petrochemicals, water treatment, and metallurgy, ensuring uninterrupted power supply and stable operation of the system 7×24 hours.

Brand: Emerson, Origin: USA. Original factory standard warranty of 12 months. Protection level: IP20. Adopting the 1D series standard rack structure, supporting DIN rail quick installation without tools, compatible with the standard cabinets of Ovation 1D series. Can be seamlessly integrated with 1D series controllers, I/O modules to build a complete distributed control system power supply architecture. 

II. Core Functional Characteristics

1. High-stability DC output, precise power supply

The industrial-grade isolated voltage regulation circuit is adopted, with a wide input voltage range and a stable output of 24VDC. The output accuracy is ≤±0.5%, which can precisely meet the power supply requirements of the 1D series controllers and I/O modules, avoiding abnormal control or equipment damage caused by voltage fluctuations. An efficient power conversion circuit is built-in, with a conversion efficiency of ≥90%, low power consumption, and low heat generation. It ensures stable and reliable operation over a long period.

2. Full protection circuit design, safe and reliable

Multiple protection functions such as overvoltage, overcurrent, short circuit, reverse connection, and surge are integrated. When the output is overloaded, short-circuited, or the input is reversed, the module automatically cuts off the output and triggers an alarm to protect the core equipment such as the controller and I/O module from damage; after the fault is resolved, it automatically resumes power supply without manual intervention, enhancing system safety and fault tolerance. An EMI filter circuit is built-in to effectively suppress grid harmonic interference and is suitable for industrial complex grid environments.

3. Redundant parallel operation, uninterrupted power supply

Support for dual-module redundant parallel operation. It can be combined with the same model 1D54561G01 or G02 power modules to form a redundant power supply system. The two power sources are in real-time load balancing. When a single module fails, it automatically switches seamlessly without power interruption or disturbance, completely eliminating the risk of single-point power failure and ensuring continuous system operation, meeting the high availability requirements of process industries.

4. Wide temperature and strong environmental adaptability, suitable for harsh scenarios

The enclosure is made of reinforced metal material, and the surface is treated with anti-corrosion and anti-static coatings, possessing dustproof, anti-vibration, and anti-electromagnetic interference capabilities. It can adapt to industrial site environments of -20℃ to +60℃ high temperature, dust, humidity, and strong electromagnetic interference. The internal core components are all of industrial-grade high-reliability specifications, having undergone strict aging tests and operational verification, with an average failure-free time (MTBF) of ≥500,000 hours, ensuring stable long-term operation performance and a long service life.

5. Intelligent status monitoring and alarm, convenient operation and maintenance

Built-in intelligent monitoring circuit, which monitors input voltage, output voltage, output current, temperature, and fault status in real time. The operation status (normal, alarm, fault) is displayed intuitively through the panel indicator lights. When a fault occurs, it automatically generates an alarm signal and uploads it to the Ovation system, accurately locating the power supply fault, facilitating rapid troubleshooting and replacement, and reducing the difficulty of operation and downtime risks. Support for hot swapping, allowing online replacement without downtime, making maintenance convenient.

6. Environmental protection compliance and authoritative certifications
