Electrical Control and Temperature Control Devices of the Power Supply Burn-in Cart |
| A |
Wiring Method: |
Products are DC-powered only; each position is supplied at 13.5 V / 15 A; high-temperature aviation connectors are installed on the burn-in cabinet |
| B |
Panel Function Keys: |
Input AC voltage display, start switch, emergency stop switch |
| C |
Temperature Control Accuracy of the Product Area: |
Enclosed product area fitted with a heat-insulated glass door; temperature control range 50 to 105 °C; temperature uniformity within ±5 °C; temperature rise from ambient to 105 °C in less than 15 minutes |
| D |
Temperature Control Principle of the Product Area: |
Low-temperature heating with over-temperature exhaust |
| E |
Power Distribution and Control Method: |
380 V three-phase five-wire power distribution; PC monitoring and manual electrical control. Burn-in time can be set by the user in minutes |
| F |
Power Distribution Capacity: |
200 W x 40 units / 0.8 = approx. 10.0 kW, calculated at 80% efficiency of the power supplies under test; the burn-in cabinet's power supply, exhaust and heating are rated at 28 kW; actual power consumption is calculated at approx. 38 kW |
| G |
Control Mode: |
Electrical control with manual/automatic switching; burn-in time supports fixed 1.5 h / 2 h / 4 h / 6 h / 12 h modes and user-defined manual settings, e.g. 2 hours 10 minutes |
| H |
Safety Protection: |
Equipment grounding protection, leakage circuit breaker protection, smoke-alarm automatic power cutoff, and the door can only be opened once the target temperature is reached |
| I |
Control Cabinet Configuration: |
Optional: none |
| 4 |
Main System Functions |
| A |
Suitable for the burn-in of precision components such as BMS controllers, radar controllers and cameras |
| B |
Dedicated monitoring software can be professionally developed in house, with independent intellectual property rights and no legal risk |
| C |
The dedicated burn-in monitoring software includes lifetime upgrade service and strong scalability, avoiding repeated investment in equipment |
| D |
Burn-in parameters, time settings and ON/OFF sequence editing (power-on/off testing of the units under test); programmable functions such as automatic voltage switching and load switching |
| E |
Automatic timed power-off after the burn-in of the units under test is completed, enabling unattended operation |
| F |
The PC automatically displays whether the power supplies under test pass or fail; the window view of multiple carts facilitates centralized management, reduces operators and improves production efficiency |
| G |
The PC can store burn-in data reports of the power supplies under test, making process parameters traceable; it also supports barcode scanning and upload to the MES system |
