Cosmic LRS-350 Enclosure Mounting Plate

The Cosmic LRS-350 Enclosure Mounting Plate is a purpose-built PETG mounting plate for securing a Mean Well LRS-350 power supply inside compatible controller enclosures. It gives your build a clean, rigid mounting point without improvised brackets, loose spacer stacks, or drilling through the enclosure base.

Each plate is printed in black heavy-wall PETG, the same material style used across our other Cosmic mounts and brackets, and includes four matched M4x10mm 304 stainless steel screws for attaching the power supply to the plate.

Key Features

Purpose-Built for the Mean Well LRS-350

The plate is designed around the Mean Well LRS-350 power supply footprint, giving you a clean way to secure the PSU inside compatible controller enclosures.

Compatible Enclosure Fitments

Heavy-Wall PETG Construction

Printed in black PETG with a strong, practical geometry for controller enclosure use. The open-frame design keeps the plate lightweight while still providing a rigid mounting platform.

Matched Stainless Hardware Included

Each mounting plate includes four M4x10mm 304 stainless steel screws matched to the 7mm plate thickness and Mean Well LRS-350 mounting depth. No separate hardware run required.

Cleaner Controller Layouts
