AEP7D-25

The AEP7D-25 is a Yokogawa primary power distribution unit for distributing incoming power to equipment installed in the same control cabinet. It uses a dual-input distribution arrangement, with separate output groups associated with each input supply. The -2 configuration is rated for 220 to 240 V AC input, while the -5 suffix identifies the basic type without explosion protection.

Power Distribution Architecture

The AEP7D distributes incoming power to equipment installed within the same cabinet. Its two input terminals, TM1 and TM2, supply separate groups of distribution connectors. In the dual-input arrangement, each supply feeds seven corresponding output ports, allowing two independent power sources to serve separate equipment groups.

The distribution structure also supports a configuration in which the two inputs are connected in parallel, allowing one incoming supply to feed all 14 output ports. This arrangement differs from dual-source operation and should be selected according to the intended cabinet power distribution design.

Model and Suffix Identification

The AEP7D model uses suffix codes to identify its input voltage and protection configuration:

Code	Description
AEP7D	Primary Power Supply Bus Unit
-2	220 to 240 V AC input
-5	Basic type without explosion protection

The complete ordering number AEP7D-25 therefore identifies the 220 to 240 V AC input version with the basic, non-explosion-protected configuration.

Frequently Asked Questions

Q: What is the input voltage requirement for the AEP7D-25?

A: The specified input voltage is 220 to 240 V AC. The maximum input current is 20 A for the complete unit, with a maximum of 6 A per distribution port.

Q: Does the AEP7D-25 support dual power supply connections?

A: Yes. The AEP7D supports two separate power inputs, each feeding its corresponding group of seven distribution ports. The two inputs can also be connected in parallel for single-source distribution to 14 ports.

Q: Is the AEP7D-25 an explosion-protected version?

A: No. The -5 suffix identifies the basic configuration without explosion protection. Explosion-protection requirements should be checked against the applicable AEP7D ordering codes and installation documentation.
