| Distribution cabinet size(mm) | L600*W1320*H1980 |
| Electrical design | 1.Incoming line: three-phase 380V / 68A |
| 2.Power distribution: AC output adopts three-phase five-wire system, single-phase voltage supplies power to the power module, and three-phase equalization is carried out in layers according to a b c a b c | |
| 3.Control: the power output of each layer can be controlled by monitoring | |
| 4.Including 22-inch liquid crystal display and keyboard, LCD human interactive interface, etc | |
| 1.Overall layout: the aging cabinet contains the product area and the isolation module area, and the two areas are isolated. There are 6 layers in the burn-in cabinet product area, 3 slots per layer, 1pcs PSU per layer, 6pcs isolation module | |
| 2.Connection method: adopt hard connection method, and configure the fixed external interface in the burn-in cabinet, including power supply output, load input, 485 signal,address signal; the tested product passes the special old Adapting and docking with the fixture | |
| 3.Interface terminal: The female end of the DL17 connector is selected. When the backplane is designed, each slot corresponds to two DL17 connectors. 2 0 # terminals forpower supply output, 2 0 # terminals for load input,485 communication signals use 2 20 # small signal terminals, and slot address signals (0 ~ 31) use 6 20 # small signal terminals | |
| 4.Air duct design: adopt air inlet at the bottom and one or two fans at the top | |
| 5.Temperature control: (room temperature + 10 ℃) ~ 60 ℃, smooth and adjustable | |
| 6.Heat capacity design: 13.5kW (2.25kW * 6) | |
| 7.Safety regulation design: meet safety regulation, fire prevention and emergency protection functions | |
| Safety regulation design: meet safety regulation, fire prevention and emergency protection functions | 1.PC: support more than one 485 serial communication, Windows 7 system, hard disk 500G. Equipped with 22-inch monitor, mouse and keyboard, wireless barcode gun and other equipment. The shell of the computer host needs to be grounded |
| 2.General monitoring: 1-way 485 communicates with PC, 4-way downlink 485 communicates with 4 types of monitoring subsystems including power module, isolation module, power environment and tested product | |
| 3.PSU monitoring: monitor each power supply module through 485 serial communication, 485 tool board realizes the conversion of the power module backplane can be Offline settings burn-in cabinet 485 to PSU CAN, the CAN address of | |
| 4.Load isolation module monitoring: monitor each isolation module through 485 serial communication, 485 tool board realizes the conversion of burn-in cabinet 485 to CAN, and the CAN address of the backplane can be offline Settings | |
| 5.Power environment monitoring: each layer of power supply, fan switch can be individually controlled, each slot provides a set of voltage (0 ~ 100V), current (0 ~ 100A), temperature,smoke sensing sampling information | |
| Monitoring softwa | 1.485 receives the command from the host computer, and then monitors the power module through CAN accordingly |
| 2.The 485 interface meets the protocol, realizes the output voltage and current limit setting commands, and realizes the output voltage, current, alarm status and other information query commands | |
| 3.485 receives the commands from the host computer, monitors each monitoring unit, realizes the on and off setting commands of each switch, and realizes the information query commands such as voltage, current, temperature, smoke status, etc. | |
| 4.Manage and control power module monitoring, load isolation module monitoring,burn-in cabinet power environment monitoring and product under test monitoring through 4 downstream 485 interfaces, and PC through 1 upstream 485 interface Complete monitoring information interaction | |
| 5.It can automatically handle the abnormality of the downstream cabinet equipment (temperature, voltage, current, etc.) in real time, parameter adjustment, control restart and reset,and record alarms | |
| Machine protection, alarm, and control technical requirements |
Cabinet smoke, over temperature protection |
| Cabinet heat dissipation: single load cabinet product area has 6KW heat dissipation capacity | |
| Leakage protection: a leakage protection function that matches the power input to the power consumption of the device, and a 30mA leakage protection circuit breaker is installed on the AC side |
