In the fields of power supply manufacturing, electronic equipment production and quality control, aging test equipment is the core equipment that ensures product reliability, eliminates early failures, and realizes the closed-loop of factory quality. Taking the CPET series of computer monitoring type electronic load temperature-controlled aging test equipment as an example, these devices simulate harsh conditions such as high temperature, high load and long-term operation to allow products to complete "extreme trials" before leaving the factory. This reduces the failure rate during after-sales service and improves the stability of the product throughout its entire life cycle. This is the core logic why major manufacturers are increasingly introducing aging test equipment.
As a national-level specialized, innovative "little giant" enterprise, a national-level high-tech enterprise, a Guangdong Province Engineering Technology Research Center for New Energy Power Electronic Intelligent Testing Technology and Complete Equipment, a Shenzhen High-tech Enterprise, and a Shenzhen Double-Soft Enterprise, CPET Kexing Yuan has been deeply engaged in the field of power electronic testing for over a decade. With its fully independent core technologies and mature solutions, it has become a long-term testing partner for over 4000 industry leaders worldwide, including Huawei, BYD, Philips, Optibar, Samsung, and Luxeon Lighting. The stability and professionalism of its equipment have been fully verified in the aging verification of products with billions of units.
I. The core value of aging testing equipment: Why is aging testing necessary?
Taking power supply products as an example (server power supplies, PC power supplies, industrial power supplies, consumer electronic power supplies, special and military power supplies, adapters, chargers, LED driving power supplies, etc.), during the early usage stage of these products, hidden faults such as poor soldering, component deterioration, and parameter drift are prone to occur - these faults are difficult to detect through conventional testing, but will gradually manifest in the later daily use, directly affecting the product reputation and enterprise credibility. The aging test equipment uses accelerated stress testing to concentrate the problems that may be exposed during long-term use of the products within a short period of time for inspection. Its core value mainly lies in the following three points:
● Eliminate early failure products: Through continuous operation under extreme pressure loads, quickly eliminate products with process defects and poor components, avoiding substandard products from entering the market, significantly reducing after-sales maintenance costs and brand damage.
● Stabilize product performance: Let the power supply complete "acclimatization" under high-temperature and full-load conditions, optimize the stability of output parameters, ensure that the product meets performance standards and operates stably for a long time, and reduce the probability of faults during use.
● Data-based quality traceability: Accurately record core test data such as voltage, current, power, and efficiency throughout the process, automatically generate traceable reports, perfectly adapting to various quality management system requirements, and achieving traceability, traceability, and controllability of quality.
II. CPET Kexinyuan Aging Testing Equipment: Analysis of Structure and Core System
The CPET Open-Type/Water-Heated Type Computer Monitoring Electronic Load Aging Test Equipment adopts a modular architecture design. It consists of four core components: the aging cabinet, the electrical control system, the electronic load module (embedded in the aging cabinet and divided into independent zones), and the computer monitoring software. It strikes a balance between versatility and professionalism, and can flexibly adapt to the testing requirements of different types and specifications of power supplies, precisely matching the large-scale production and refined testing needs of major manufacturers.
1. Power Supply, Wiring and Precautionary Measures (Safety Foundation)
● Equipment Power Supply: Utilize three-phase AC380V/50Hz or single-phase AC220V/50Hz power supply, with mandatory grounding (equipped with 6mm² dedicated ground wire), and an additional leakage switch is installed at the front end. This approach aims to prevent electrical shock and equipment damage from the source, thereby eliminating safety risks such as electric shock and equipment failure.
● Wire Selection Standards: Strictly require the use of national standard multi-core copper wires, and prohibit the use of non-standard or damaged wires. This fundamentally eliminates potential safety hazards such as electric shock, short circuits, and fires, ensuring the safety of testing.
● Smoke Detection Protection: Both the product area and the load area are equipped with smoke sensors. Once abnormal situations such as smoke or fire are detected, the equipment will automatically cut off the main power supply, preventing the occurrence of fire accidents at the front end and safeguarding the safety of equipment, products, and personnel.
2. Electronic Load Module (Test Core)
The equipment can select dozens of load modules such as CP8102, CP8104, and CP8108, which are fully self-owned intellectual property and independently developed and produced, based on the voltage, current and power requirements of the tested power supply. This enables it to fully meet the diverse testing needs of its partners. The load modules support 5 load modes, covering the vast majority of power supply testing scenarios and enabling precise testing of different types of power supplies.
● CC (Constant Current) mode: Compatible with constant voltage power supplies, it can maintain a constant pulling current, accurately testing the load capacity and stability of the constant voltage power supply.
● CV (Constant Voltage) mode: Compatible with constant current power supplies, it can stably output the test voltage, ensuring the accuracy and reliability of the constant current power supply testing.
● CR (Constant Resistance) / CP (Constant Power) mode: Simulates the impedance and power consumption of real electrical devices, reproducing the actual usage conditions of the product, making the test results more valuable for reference.
● LED Load Mode: Specifically designed for the LED lighting industry, it can precisely simulate the Volt-Ampere characteristics of LED bulbs, matching the actual working scenarios of LED driver power supplies. The test is more targeted and professional.
In addition, the load module supports multi-channel parallel connection, allowing for flexible expansion of high-power testing scenarios； at the same time, it comes with three protection mechanisms for over-temperature, over-current, and over-power, providing comprehensive safety protection during the testing process, avoiding damage to the equipment and the tested products, and meeting the testing requirements of large-scale and high-load production.
3. Computer monitoring software (Intelligent Brain)
The computer monitoring software acts as the "command center" for the aging test equipment, enabling the entire testing process to be automatically controlled. It is user-friendly, comprehensive in function, and meets the requirements for efficient production line operation and refined management. It can significantly reduce labor costs:
● Simple operation process: Login → Parameter editing → Parameter import → Start aging. The steps are clear and easy to understand, and one can get started without professional training; each model only needs to be learned once, and later one can directly import aging parameters with a single click to improve the testing efficiency of the production line.
● Full coverage of core functions: Supports custom aging duration, time sequence switching, and can flexibly set voltage/current upper and lower limit judgment standards; real-time curve monitoring of the testing status, abnormal situations trigger automatic alarms, and at the same time, generate Excel reports and conduct SPC process capability analysis to achieve visualized, traceable, and analyzable testing data.
● Hierarchical permission management: Sets up administrator, engineer, and technician three-level user permissions, precisely adapting to the operation needs of different positions in the production line. It not only ensures operational safety but also prevents test parameter leakage or accidental operation, and is suitable for the requirements of large-scale factory standardized management.

Taking the aging test of a 12V/1A adapter as an example, the complete operation process of the CPET Kexing Computer Monitoring Type Electronic Load Aging Test Equipment is clear and efficient, with standardized steps. It meets the batch testing requirements of the production line. The details are as follows:
● Equipment placement: Place it in an indoor area with dry and ventilated conditions, with the environmental temperature not exceeding 35℃. Leave at least 0.5m of space around the equipment for heat dissipation to avoid affecting the test accuracy and the service life of the equipment.● Wiring connection: Complete the power-on of the equipment → Insert the product into the aging cabinet (using various methods such as plugs, sockets, terminals, or wire bundles) → Confirm the grounding situation. Ensure that the wiring is secure and the grounding is good throughout the process, and eliminate potential hazards such as poor contact and electric shock.
● Software settings: Log in to the system → Edit test parameters (select CC mode, set current 1A, voltage range 11.4–12.6V) → Set the aging time → Import parameters → Start the aging program. The entire process can be operated with one click, without the need for manual intervention.
● Operation monitoring: Real-time determine the test status through the channel indicator lights - green = normal operation, red = product failure, black = empty position; When the equipment detects an abnormality, it will automatically alarm and simultaneously record the abnormal data, facilitating later traceability analysis and process optimization.
IV. Safety Operating Procedures: The "Red Line" for the Aging Test Equipment
The aging test equipment involves dangerous factors such as high temperature, high pressure, and high current. During the operation, the following safety guidelines must be strictly followed to prevent any safety incidents and ensure the safety of personnel, equipment, and products:
