An illustrative engineering case showing how a 90W 24V AC-DC power adapter with C14 input and bare-wire output can be configured for industrial machine vision equipment.
The project demonstrates the importance of matching an AC-DC power adapter not only to the equipment’s electrical requirements but also to its mechanical and installation conditions.
With flexible cable and connection configurations, XJK can support OEM equipment manufacturers looking for customized 24V power adapter solutions.
A German industrial automation equipment manufacturer was evaluating an external AC-DC power solution for a new machine vision inspection system.
The equipment was designed for automated inspection tasks on production lines, using industrial cameras, vision controllers, sensors, and other electronic components to identify product defects and verify manufacturing quality.
The customer required a compact 24V DC power adapter that could provide sufficient power for the compatible electronic loads while allowing convenient integration into the equipment’s electrical system.
Rather than using a standard DC barrel connector, the customer preferred a bare-wire DC output to connect the power supply directly to the equipment’s internal terminal block.
Based on the initial requirements, XJK proposed a 90W AC-DC power adapter with a 24V DC output, rated at 3.75A, featuring a C14 AC input and bare-wire output cable.
However, selecting the correct electrical rating was only the first step. Cable configuration, terminal compatibility, installation space, and equipment integration also needed to be reviewed before the final configuration could be confirmed.
| Parameter | Initial Requirement |
|---|---|
| Application | Industrial Machine Vision Inspection System |
| Power Supply Type | External AC-DC Power Adapter |
| Rated Output Power | 90W |
| Output Voltage | 24V DC |
| Rated Output Current | 3.75A |
| AC Input Connection | IEC C14 |
| DC Output Connection | Bare Wire |
| Installation | External power supply with equipment-side terminal connection |
| Customization | Cable and connection configuration |
During the initial technical review, the customer focused on three main requirements: electrical compatibility, bare-wire connection, and cable configuration.
The machine vision system included several electronic components, such as vision controllers, industrial cameras, sensors, and control modules.
These components required compatible DC power inputs, and the customer wanted to use a centralized 24V DC power source for the equipment’s designated 24V loads.
The proposed 90W rating provided a maximum rated output current of 3.75A at 24V DC.
Before confirming the power adapter, the total continuous load, peak current demand, startup behavior, and power requirements of the connected devices needed to be checked.
The objective was to ensure that the selected adapter could support the intended load without exceeding its rated operating limits.
The customer preferred a bare-wire DC output instead of a conventional barrel connector.
This was related to the equipment’s internal electrical design, where DC power was distributed through a terminal block.
A bare-wire output could simplify integration into this type of wiring arrangement, but several details needed to be confirmed:
These details were important because an electrically compatible power adapter could still require changes to its output cable configuration before it could be integrated into the equipment.
The customer also needed to consider the distance between the external power adapter and the equipment’s internal connection point.
An unsuitable DC cable length could create unnecessary cable routing difficulties or affect installation convenience.
The cable specification therefore needed to account for the equipment layout, installation distance, current capacity, and potential voltage drop.
XJK reviewed these requirements as part of the proposed power adapter configuration rather than treating the request as a standard off-the-shelf purchase.
Based on the initial electrical requirements, XJK proposed a 90W 24V AC-DC power adapter with a C14 AC input and bare-wire DC output.
The proposed configuration was designed around the following electrical specifications:
| Specification | Proposed Configuration |
|---|---|
| Rated Power | 90W |
| Output Voltage | 24V DC |
| Output Current | 3.75A |
| AC Input | IEC C14 |
| DC Output | Bare Wire |
| Product Type | Desktop AC-DC Power Adapter |
| Application | Industrial Machine Vision Equipment |
The C14 AC inlet provided a detachable AC power connection, while the bare-wire DC output was intended for connection to the equipment’s internal terminal block.
This configuration offered a practical starting point for the customer’s equipment integration requirements.
However, the initial proposal did not automatically resolve every installation detail. The DC cable specification and bare-wire preparation still needed to be confirmed against the customer’s equipment design.
Our engineering process helps device manufacturers move efficiently from requirement definition to production-ready power solutions.

After reviewing the initial configuration, the next step was to clarify the mechanical and electrical details of the output cable.
For industrial equipment manufacturers, these seemingly small details can affect installation efficiency, wiring reliability, and compatibility with the final equipment assembly.
XJK focused on three areas during the configuration review.
The DC cable length needed to match the distance between the external adapter and the equipment’s internal terminal block.
An excessively short cable could make installation difficult, while an unnecessarily long cable could complicate cable routing and equipment assembly.
The cable length therefore needed to be confirmed according to the actual equipment layout.
In addition, the cable specification had to be evaluated for its current-carrying capacity and voltage drop under the intended operating conditions.
The customer required a bare-wire output that could be connected to the equipment’s internal terminal block.
XJK reviewed the relevant cable details, including conductor size, stripping length, and terminal compatibility.
The purpose was to ensure that the output cable could be properly prepared and securely connected during equipment assembly.
Polarity identification was also an important consideration. The positive and negative conductors needed to be clearly identified according to the confirmed wiring specification.
Although the required rated output was 24V DC at up to 3.75A, the connected equipment’s actual load profile also needed to be considered.
Industrial machine vision systems may contain multiple electronic components with different power consumption characteristics.
The total continuous load, startup current, and any transient demand needed to be reviewed before confirming the final power adapter selection.
The 90W rating represented the adapter’s maximum rated output power, not a guarantee that every combination of cameras, controllers, and accessories could be powered simultaneously.
This review helped establish whether the proposed configuration was appropriate for the intended equipment.
Following the configuration review, the 90W 24V AC-DC power adapter provided a defined starting configuration for the machine vision equipment application.
The key product specifications were:
| Parameter | Configuration |
|---|---|
| Product Type | AC-DC Power Adapter |
| Rated Output Power | 90W |
| Output Voltage | 24V DC |
| Rated Output Current | 3.75A |
| AC Input Connection | IEC C14 |
| DC Output Connection | Bare Wire |
| Cable Configuration | According to confirmed project requirements |
| Target Application | Industrial Machine Vision Inspection Systems |
The main advantage of this configuration was the combination of a 24V DC output and a bare-wire connection suitable for equipment designs using internal terminal blocks.
For equipment manufacturers, confirming the cable and connection details alongside the electrical specifications can help reduce integration uncertainty during product development and assembly.
The project illustrates why power adapter selection should consider more than rated voltage and wattage. Electrical load requirements, cable specifications, connection methods, and installation conditions all contribute to a suitable power solution.
A 90W 24V power adapter can be suitable for machine vision equipment when the connected 24V DC loads fall within its rated output capability.
The total continuous power consumption, startup current, and peak load requirements should be checked before selecting the adapter.
A 90W power adapter with a 24V DC output has a rated output current of 3.75A.
The connected equipment should not exceed the adapter’s specified output limits.
A bare-wire output can be useful when equipment uses internal terminal blocks for DC power connections.
It allows the output cable to be terminated according to the equipment’s wiring design, provided that conductor size, polarity, stripping length, and terminal compatibility are properly specified.
Cable length may be customizable depending on the power adapter platform and project requirements.
The required length should be confirmed together with conductor size, output current, voltage drop, and installation conditions.
XJK can review OEM project requirements for suitable AC-DC power adapter configurations.
Depending on the selected platform, customization may include output cable length, bare-wire preparation, DC connector options, labeling, and other project-specific requirements.
