[Core Summary]
R&D laboratories and training platforms often have dozens of boards powered simultaneously, with a set of sockets, adapters, and adjustable power supplies, resulting in a cluttered desktop and numerous potential hazards. Taking the Aim-TTi CPX series dual-channel DC power supply as an example, a single device can provide two independent outputs, coupled with remote interfaces for centralized management, consolidating scattered power supplies into a traceable power source. This article serves as a typical application reference, and the listed specifications are indicative values based on product documentation, rather than specific project delivery commitments.
Background and Pain Points
Current problem situation
Each board card comes with a wall plug adapter, and with desktop cables intertwined, pulling the wrong one can cause a power outage.
A dual-power operational amplifier circuit is required, with two single-channel power supplies connected in series, which is cumbersome to connect and prone to reverse connections.
During teaching and training rotations, it is challenging for teachers to uniformly check the set values each time students reconnect the wires.
The cost of pain points
A misconnected power supply can cause a circuit board to burn, and while the loss of a single sample may not be a significant issue, it can significantly delay project milestones.
The power supply parameters are recorded by handwriting, making it unclear who set what voltage during the review.
With more devices and insufficient outlets, connecting extension cords in series poses electrical hazards.
Solution and Deployment
Selection Basis
**CPX Series Dual-channel**: Two independent adjustable outputs, capable of covering both positive and dual power supplies, eliminating the need for series connection.
**MX Series Precision**: For circuits with high requirements for power ripple and load regulation, providing cleaner power supply.
Supports LAN/USB remote reading and setting, suitable for incorporating multiple power supplies into a single control software.
Deployment Method (typical configuration, for reference)
Each workbench is equipped with one CPX dual-channel, with the positive channel supplying the digital part and the negative channel supplying the analog part.
For critical projects, use MX precision power supplies to separately power sensitive circuits, reducing noise coupling.
Write set values into the ledger through a remote interface, recording who changed the parameters and to what extent.
Results and Value (Indicative)
Typical Benefits
**Clean Desktop**：One unit replaces two or three adapters, reducing cables by half.
**Wiring Convenience**：Dual independent paths without series connection reduce the risk of reverse wiring, making it easy for novices to get started quickly.
**Management Visibility**：Remote access to settings facilitates unified verification for training and research.
Reduced Sample Loss, Stabilized Project Timeline, and Focused Attention on the Circuit Itself for Both Teachers and Students.
Application Boundaries
The value of this solution depends on whether the single-channel current and power cover the tested board. High-current power-level circuits require additional higher-power models; remote functionality is confirmed based on model support.
Key Parameter Table
A Suggestion for Laboratory Administrators
After consolidating power supplies into one unit, it is recommended to label the purpose of each channel for clear visibility. Regularly verify the load using readback current, which is much more convenient than waiting for a fault to occur.
The above parameters are taken from Aim-TTi's public product information, and specific specifications are subject to the original datasheet; the actual power supply scheme needs to be determined based on the board power consumption and laboratory power distribution conditions.
