1.burn in test chamber The control cabinet is the "brain" of the entire intelligent burn-in test system, which can control the operation of the entire system. Generally, one control cabinet can control several burn-in cabinets, with built-in components such as input general power distribution, computer, monitor, mouse, keyboard, smoke sensor, emergency stop, indicator light and so on. If it is necessary to provide a burn-in test system with different input AC voltages, it can also be equipped with a multi-tap transformer; If a burn-in test system with programmable input DC voltage is required, a programmable DC power supply system can also be installed internally. 2.Burn-in cabinet Burn-in cabinet is the "trunk" of the entire intelligent aging test system. It has built-in thermostatic control device, programmable load, product interface board, smoke sensor, emergency stop, indicator light and other components. The general design is divided into two areas: product area and load area. The product area mainly provides editable high temperature environment for burn-in test products, products are placed on the table and product interface; The load area houses the programmable load, control board,auxiliary power supply, and other operating support components.In some application fields, cabinet can be divided into load cabinet or power cabinet, product cabinet or trolley form, one is to better use the floor space, the other is flexible to meet the manufacturing needs of customers.   3.Water temperature tank,Air cabinet In some applications where products require water cooling units, CPET can also provide customers with water temperature tanks. The water temperature tank provides the system with programmable temperature of the liquid heat cycle medium, instead of the air heat cycle medium. The water temperature cabinet can communicate with the upper computer software to set and monitor the water temperature, flow rate and pressure.

It is applied to the production aging process of power supplies and is suitable for all power supply aging equipment in CPET production. 1.The visual aging parameter setting interface includes load mode, load value, product specification range, aging temperature and other Settings. The set values can be saved in file form, and users can import them with one click to start aging immediately. 2. Real-time load status monitoring, graphical product PASS/FAIL judgment display, can monitor the input and output working status of each product, including output current, output voltage, input voltage, input current, input power, power factor, efficiency and other electrical parameters. 3. Programmable aging timing, including input ON/OFF switch timing, input voltage selection timing, etc. 4. The entire aging process data is automatically recorded. 5. The input and output characteristic curves of the product can be viewed in real time. 6. It integrates data recording, analysis and statistics functions. Historical data records can be searched based on product barcodes or models, etc., and has functions such as generating P control charts and calculating Cpk.

1.The aging cabinet adopts a closed design and is equipped with fans and exhaust ports, which can control the environmental temperature for aging tests. The interior is a multi-layer pull-out platform, which facilitates the loading and unloading of products. The adapter board on the rack provides various interfaces required for product aging tests, including input power, input electrical signals, input loads, and monitoring of product output signals, etc. They are respectively connected to the control cabinet, signal generator, and load through wires. 2. The control cabinet is mainly used to control the power-on and power-off of products. The input power of each product in the system is independently controlled. When a certain product malfunctions, the system will cut off its input power. The operator can safely move it away while the system is working instead of waiting until the aging test is completed, which improves production efficiency. In addition, the control box can also switch the output signal of the product to the monitoring instrument for measurement. The monitoring test software will determine whether the product is working properly based on the measurement data. 3. The monitoring instrument adopts NI data acquisition cards, mainly to measure the output signals of the products. Fast measurement speed is its advantage, and at the same time, its high cost performance can also save costs for enterprises. 4. Industrial computers are mainly equipped with monitoring test software and NI data acquisition cards.

In fact, burn-in test using the same device as the aging test, but it's called differently in various places. As shown in the picture Then what about the aging test system? burn-in test system provides programmable input electrical parameters, output electrical parameters, environmental parameters, working mode and test timing sequence for the tested products. It collects the running data of the products  in real time during the burn-in process for status detection and judgment, and carries out data statistics, analysis and comparison after burn-in. As far as I know, there is a professional manufacturer of aging test systems in China, which seems to be called Zhongkeyuan Electronics Co., LTD. (CPET). CPET intelligent burn-in test system innovative use of portable cabinet structure, convenient for customers flexible layout, relocation and movement. Generally, there are two parts: control cabinet and burn-in cabinet. For the burn-in of some liquid cooling  products, it is also necessary to provide temperature cabinet, air cabinet and other constant temperature heat dissipation devices. In some areas with high power or large volume of burn-in products, burn-in cabinets can be decomposed into load cabinets or power cabinets, product cabinets or carts in order to effectively use the floor space.
