50×44mm Aluminum Power Supply and Industrial Control Enclosure

Boyuan 50×44mm Aluminum Power Supply and Industrial Control Enclosure is a mid-sized electronic device housing manufactured with an aluminum alloy extrusion structure, with an external cross-section size of 50mm (width) × 44mm (height), and the length can be customized arbitrarily according to actual equipment requirements.

The product is formed by aluminum profile extrusion, with a fixed main body cross-section size. It can be cut according to the actual length of the equipment, and final assembly is completed through end plates, CNC machining, and other supporting processes.

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 of the housing is designed with standard circuit board card slots, and the PCB can be directly inserted and fixed without additional screws, greatly improving assembly efficiency.

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.

The core value of 50×44mm lies in its "wide body and large space" — the 50mm width can accommodate standard wide PCBs and multiple interface layouts, and the 44mm height provides ample internal space for installing taller components.

This specification is especially suitable for power modules, power amplifiers, industrial controllers, measuring instruments, communication base station equipment, data acquisition and transmission equipment, motor drive modules, medical testing instruments, and other mid-sized electronic equipment with high requirements for internal space.

Boyuan Hardware has focused on aluminum enclosure and aluminum chassis manufacturing for over 20 years, with approximately 10,000 square meters of production factory space, and can provide custom aluminum enclosure machining according to customer drawings, samples, or size requirements.

Product Core Advantages

01 | 50×44mm Ample Space Design

The 50mm wide × 44mm high cross-section size provides ample internal space for mid-sized electronic equipment.

The 50mm width can accommodate wider PCB layouts and side-by-side design of multiple interfaces; the 44mm height provides greater component mounting space, can accommodate taller components such as electrolytic capacitors, transformers, heat sinks, and relays, and also supports double-sided PCB design, meeting the integration needs of 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 44mm height can accommodate double-layer PCB stacking or high-power devices with heat sinks, providing a reliable packaging solution for high-power electronic equipment.

04 | CNC Custom Machining Support

The standard profile is only the starting point.

Boyuan Hardware can perform CNC machining on the 50×44mm aluminum enclosure according to customer drawings, including:

• Interface openings (USB, RJ45, power interfaces, aviation plugs, etc.)
• Screw holes and positioning holes
• Threaded holes and counterbore holes
• Grooves and steps
• Heat dissipation slots and ventilation holes
• Chamfering
• Other custom structures

05 | Length Customizable to Product

50×44mm is the cross-section specification of the enclosure, and the 50×44mm Aluminum Power Supply and Industrial Control Enclosure 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

The thermal conductivity of aluminum alloy is about 200W/(m·K). Combined with the larger surface area of 50×44mm, it can effectively conduct and dissipate heat generated by internal components. For equipment with large heat generation such as power modules and power amplifiers, the aluminum enclosure itself is an efficient heat sink, which can extend 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.

What Products Is the 50×44mm Aluminum Enclosure Suitable For?

50×44mm belongs to the ample-space aluminum enclosure category — the 50mm width supports side-by-side layout of multiple interfaces, and the 44mm height can accommodate taller components and heat sinks. The 44mm height is the core feature that distinguishes this specification from small enclosures, enabling it to carry electronic equipment with greater power and taller components.

• DC-DC converter modules
• UPS power supply modules
• Charger modules

Why is 50×44mm suitable for power modules? Power modules usually need to accommodate taller components such as electrolytic capacitors (typically 25-35mm in height), transformers, and heat sinks. The 44mm height provides ample mounting space, while the 50mm width can accommodate wide PCB layouts, and the aluminum alloy material also helps high-power devices dissipate heat efficiently.

2. Power Amplifiers and Audio Equipment

• Amplifier enclosures
• Audio power amplifiers
• Signal amplifier modules
• RF power amplifiers

Why is 50×44mm suitable for amplifiers? Power amplifiers need relatively large internal space to accommodate amplifier circuits, heat sinks, and power supply sections. The 44mm height can install taller components, and the aluminum alloy enclosure also serves a heat dissipation function, suitable for audio and RF amplifier equipment with large heat generation.

Product Selection Guide

If Your PCB Width Is Close to 50mm

50×44mm is an ideal choice — the 50mm width provides ample PCB routing space, and the 44mm height can accommodate taller components. Whether the actual structure is suitable can be confirmed according to PCB thickness, mounting method, and internal component height.

If Your Device Contains Taller Components

The 44mm height can accommodate taller components such as electrolytic capacitors (25-35mm), transformers, heat sinks, and relays, suitable for electronic equipment requiring larger internal space.

If Your Device Generates Significant Heat

The aluminum alloy enclosure has excellent thermal conductivity. Combined with the larger surface area of 50×44mm, it can effectively help internal components dissipate heat. Heat dissipation slots or ventilation holes can be machined on the enclosure to further enhance the heat dissipation effect.

If PCB Lengths Differ

The profile can be cut according to product length, and the same cross-section specification can adapt to products of different lengths.

If Interfaces Need to Be Installed

CNC openings can be added to the profile body or end plates. Common ones include USB, RJ45, power interfaces, aviation plugs, BNC interfaces, indicator lights, etc.

If You Need More Space

A larger aluminum profile specification can be reselected according to PCB dimensions, or a non-standard enclosure design can be carried out.
