AetherNexus K-DCU — technical drawing of the outdoor enclosure

Technical drawing derived from the supplied 3D enclosure model, in millimetres — not a photograph. The model shows the front door open, so the door is not drawn; hinges, lock hardware and the rear pole brackets are included.

K-DCUDATA CONCENTRATOR UNIT

Low-voltage AMI Data Concentrator Unit

The AetherNexus K-DCU is a modular data concentrator unit for KEPCO's low-voltage AMI, installed at the secondary side of pole-mounted or pad-mounted distribution transformers. Function units plug into a slot-type shelf in an aluminium outdoor enclosure: a power supply unit (PSU), a main system unit with an L2 switch (MSU), a communication unit and an optional transformer load-monitoring unit (EMU). The values on this page are requirements of the KEPCO purchase specification that the product is designed to.
