69×27mm Aluminum Medical Power Supply and Controller Enclosure

Boyuan 69×27mm aluminum enclosure is a wide-body, medium-height electronic device housing formed by aluminum alloy profile extrusion, with an external cross-section size of 69mm (width) × 27mm (height), and the length can be customized arbitrarily according to actual equipment requirements.

69×27mm Aluminum Medical Power Supply and Controller Enclosure 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 interior of the housing is designed with standard circuit board card slots, and the PCB can be directly inserted and fixed without additional screws.

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.

Core Advantages

01 | 27mm Height: The Critical 3mm More Than 24mm

Common wide aluminum enclosures on the market are mostly 24mm in height. The 69×27mm raises the height to 27mm while maintaining the 69mm width. This extra 3mm may seem minor, but it brings a substantial difference — accommodating components such as electrolytic capacitors around 25mm in height, small transformers, and relays. For equipment such as medical power supplies and industrial controllers that need to accommodate slightly taller components, 27mm is the "golden height" balancing a slim appearance with functional completeness.

02 | Suitable for Medical Power Supply and Controller Scenarios

69×27mm has been maturely applied in the market for medical power supply enclosures, medical device controllers, circuit board housings, and similar scenarios. Medical equipment has strict requirements for electromagnetic compatibility and heat dissipation. The aluminum alloy material provides natural electromagnetic shielding and heat dissipation advantages, making it an ideal housing choice for medical electronic equipment.

03 | Aluminum Extrusion Structure, Flexible Length Customization

The enclosure body uses 6063-T5 extruded aluminum profile, with a fixed cross-section size, and the length can be cut arbitrarily according to actual requirements. The same profile can adapt to PCBs of different lengths, facilitating series product development.

04 | Standard PCB Card Slots, Efficient Assembly

The interior is standard-equipped with circuit board card slots, and the PCB can be directly inserted and fixed without additional screws, greatly improving assembly efficiency.

05 | CNC Precision Machining Support

CNC secondary machining can be performed on the basis of the standard profile:

• Interface openings (USB, RJ45, aviation plugs, power interfaces, etc.)
• Screw holes, threaded holes, counterbore holes
• Heat dissipation slots, ventilation holes
• Button holes, indicator light holes
• Screen window openings
• Logo laser engraving, silkscreen printing

06 | Aluminum Heat Dissipation, Extending Equipment Life

Aluminum alloy has a thermal conductivity of about 200W/(m·K), which can quickly conduct heat from internal power devices, especially suitable for equipment with a certain amount of heat generation such as medical power supplies and LED drivers.

07 | IP54 Protection, Adapting to Multiple Environments

The 69×27mm aluminum enclosure can reach IP54 protection level, dustproof and splash-proof, suitable for medical, industrial, outdoor, and other usage scenarios.

08 | Electromagnetic Shielding, Anti-Interference

Aluminum alloy itself has good electromagnetic shielding performance, effectively preventing external electromagnetic interference from affecting precision circuits.

Technical Specifications

Typical Application Scenarios

1. Medical Power Supplies and Medical Device Controllers

This is the most core and differentiated application direction for 69×27mm.

69×27mm has been market-verified as a mature housing specification for medical power supplies and controllers. Medical power supplies usually need to accommodate filter capacitors (heights can reach 25mm), transformers, and heat sinks. The 27mm height provides more ample mounting space than 24mm. The aluminum alloy housing provides good electromagnetic shielding performance, meeting the EMC requirements of medical equipment, while the aluminum material is easy to clean and disinfect, conforming to the hygiene standards of medical equipment.

Applicable products: medical switching power supplies, medical device control boards, monitor modules, testing instrument housings.

2. Industrial Power Modules and LED Drivers

69×27mm Aluminum Medical Power Supply and Controller Enclosure is widely used in the power module and LED driver fields. Power modules need a wider PCB layout to accommodate power devices and multiple interfaces. The 69mm width provides ample routing space; the 27mm height can accommodate electrolytic capacitors and heat sinks. The aluminum alloy enclosure helps power devices dissipate heat efficiently, extending power supply service life.

Applicable products: switching power supply modules, LED driver power supplies, industrial power adapters, DC-DC converters.

3. GPS Modules and Positioning Tracking Equipment

69×27mm is often used for GPS module and positioning tracking equipment enclosures. GPS devices need to accommodate GPS chips, communication modules, antennas, and batteries. The 69mm width provides ample PCB space, and the 27mm thickness can accommodate higher-capacity batteries.

Applicable products: GPS/GPRS modules, vehicle GPS trackers, asset positioning devices, outdoor positioning modules.

4. Instruments and Industrial Control

Aluminum extrusion enclosures are widely used in instruments and meters, electronics, communications, automation, industrial control, and other industries. The wide-body medium-height design of 69×27mm both satisfies the large-screen display needs of instrument products and provides ample internal space to accommodate control circuits and power modules.

Applicable products: instrument and meter enclosures, industrial controllers, PLC modules, data acquisition modules, automation control equipment.

5. Shielding Boxes and Anti-Interference Applications

The electromagnetic shielding performance of the aluminum alloy material makes 69×27mm an ideal choice for precision circuit shielding boxes. The ample 27mm internal space can accommodate complex circuit systems, effectively preventing electromagnetic interference.

Applicable products: electronic shielding boxes, anti-interference device enclosures, high-frequency module shielding, precision circuit protection boxes.

69×27mm vs 69×24mm: How to Choose?

Simply put: if your device needs to accommodate electrolytic capacitors around 25mm, small transformers, or relays, choose 69×27mm; if it is only a slim control board or digital instrument, 69×24mm is sufficient.
