Product Description

The AEP7D-25 is a robust Primary Power Supply Bus Unit engineered for high-integrity power distribution within the Yokogawa CENTUM and ProSafe-RS control architectures. This module functions as a centralized power hub, receiving high-voltage AC input and distributing it reliably to multiple system components. Its primary role is to ensure that critical control nodes and field instruments receive a stable and protected power source, minimizing the risk of downtime caused by electrical instability.

Designed for high-current applications, the AEP7D-25 features heavy-duty internal busbars and specialized port protection. The unit is built to withstand high dielectric stress, featuring a 1500 V AC withstanding voltage rating, which is essential for maintaining safety standards in industrial electrical cabinets. Its compact yet heavy-duty construction makes it a staple for large-scale control systems requiring centralized power management.

Technical Specifications

Application Scenarios

• Centralized Cabinet Power: Distributing AC power to multiple redundant power supply modules in a single control rack.

• Safety Instrumented Systems (SIS): Providing the primary power rail for ProSafe-RS safety nodes where power integrity is mission-critical.

• Large-scale DCS Deployments: Managing power distribution for high-density I/O configurations across distributed control networks.

Technical Support FAQ

What happens if the 20 A total current limit is exceeded?

Exceeding the AEP7D-25 aggregate current rating can lead to excessive heat buildup and potential failure of the internal busbars. It is critical to calculate the total load of all connected ports to stay below the 20 A threshold.

Can this unit be used with 110 V AC systems?

The AEP7D-25 is specifically rated for the 220-240 V AC range. For 110 V AC applications, a different model variant (such as the AEP7D-1) should be utilized to ensure proper electrical performance and safety.
