53.4×27.5mm Aluminum Power Supply Control Module Housing

Boyuan 53.4×27.5mm Aluminum Power Supply Control Module Housing is a mid-sized electronic device housing manufactured with an aluminum alloy extrusion structure, with an external cross-section size of 53.4mm (width) × 27.5mm (height), and the length can be customized arbitrarily according to actual equipment requirements.

Compared with plastic boxes, aluminum alloy enclosures have better structural strength and a metal texture, and can achieve custom structures such as interfaces, mounting holes, threaded holes, and slots through CNC machining.

Core Advantages

01 | 53.4×27.5mm Wide Body, Moderate Design

The 53.4mm wide × 27.5mm high cross-section size provides ample internal space for mid-sized electronic equipment.

The 53.4mm width is wider than the common 52mm specification, accommodating wider PCB layouts and more side-by-side interface design, supporting multi-channel input/output interface layouts; the 27.5mm height maintains a moderate device thickness while providing greater component mounting space than slim specifications, accommodating small transformers, electrolytic capacitors (typically 20-25mm in height), relays, and medium-height components, supporting the integration needs of relatively complex circuit systems.

02 | Aluminum Extrusion Structure

The enclosure body is formed by aluminum alloy profile extrusion. The cross-section size of the aluminum extrusion enclosure is fixed, while the length can be cut according to actual product requirements. Therefore, the same specification enclosure can adapt to PCBs and electronic modules of different lengths. This structure is especially suitable for electronic products requiring series development.

03 | Suitable for PCB Mounting

The aluminum extrusion electronic enclosure can be designed with corresponding mounting slots or support structures according to the internal structure, for installing PCBs and other electronic components. The interior is standard-equipped with circuit board card slots, and the PCB can be directly inserted and fixed without additional screws. The 27.5mm height can accommodate power devices with small heat sinks or medium-height components, providing a reliable packaging solution for electronic equipment with slightly higher power.

04 | CNC Custom Machining Support

The standard profile is only the starting point. Boyuan Hardware can perform CNC machining on the 53.4×27.5mm aluminum enclosure according to customer drawings, including:

• Interface openings (USB, RJ45, aviation plugs, BNC interfaces, power interfaces, etc.)
• Screw holes and positioning holes
• Threaded holes and counterbore holes
• Heat dissipation slots and ventilation holes
• Screen window openings
• Button holes and switch holes
• Mounting holes and wall-mounting holes
• Grooves and steps
• Chamfering
• Other custom structures

05 | Length Customizable to Product

53.4×27.5mm is the cross-section specification of the enclosure, and the product length can be cut according to the actual equipment dimensions. The specific machinable length is confirmed according to material, surface treatment, and product requirements.

06 | Efficient Heat Dissipation Performance

Aluminum alloy has excellent thermal conductivity. Combined with the 53.4mm wide-body design and 27.5mm internal space, small heat sinks can be installed or internal air circulation space can be increased, effectively helping internal components dissipate heat and extending equipment service life.

07 | Metal Enclosure Combines Structure and Appearance

Aluminum alloy is lightweight and has good structural performance, while retaining a natural metal texture. Through surface treatments such as brushing, sandblasting, and anodizing, different appearance effects can be obtained, giving electronic equipment a more professional product appearance.
