Burn-in cabinet
structure and
Burn-in quantity
planning | Trolley size (mm) | L2050*W1250*H2050mm (size of a single Burn-in cabinet) |
| Number of trolley layers | 6 layers, product area depth 400mm, (6 Burn-in positions per layer) |
| Trolley height | 175mm |
| Trolley structure material | 2.0mm thick cold rolled sheet |
| Load area cooling method | Top turbine exhaust fan top row type (easy to control the ambient
temperature) |
| Layer insulation and anti-static method | Epoxy insulation board with heat dissipation holes on the surface |
| Overall burn-in room structure | Adopt mobile Burn-in split cabinet; beautiful appearance and easy
to move and combine |
Introduction to energy
recovery module
configuration, power
of the tested power
supply and Burn-in
quant | Energy recovery module control method | RS485 communication mode, upper computer uses RS232 communication
mode |
| Product burn-in mode | The burn-in process of the product is carried out by the way of
relative drag |
| Dc power isolation mode | Dc power channel adopts photoelectric isolation (communication and
power supply isolation) |
Energy recovery module design
architecture | No relay, long life design scheme (independent intellectual
property rights) |
Introduction of
electric control
and temperature
control device for
power Burn-in
cabine | Wiring | Customer specified interface; Input/output port Anderson connector |
| Panel function keys | Input AC voltage display, start switch, emergency stop switch |
Trolley power distribution and control
mode | 380V three-phase five-wire distribution; Computer monitoring and
automatic electric control |
| Trolley power distribution | A single burn-in cabinet is 3000W*36/0.85≈127KW, and the measured
power efficiency is calculated as 85% |
| Way to control | The electric control includes manual/automatic switching, which is
monitored by the computer in real time
when burn-in. The electric control cabinet can extend the automatic
switching function of AC voltage |
| Safety protection | Equipment grounding protection, leakage switch protection, smoke
alarm automatic power-off protection,
etc. |
Introduction to the
main functions of
the system | Applicable to energy storage power,current converter, inverter,
regurgitator,transverter, medical power supply and so on |
| Free configuration of self-developed special monitoring software
for power Burn-in, with independent intellectual property rights
and no legal risks |
| Use programmable electronic load module to monitor output terminal
voltage, current and power parameters |
| Dedicated monitoring software for Burn-in enjoys free final upgrade
service, powerful expansion function, saving repeated investment in
equipment |
Burn-in parameters, time setting, ON/OFF sequence editing (test of
the product being tested on and off), support for automatic voltage
switching, load
conversion and other functions can be programmed (Burn-in
parameters can be automatically switched in a fixed time period) |
| The function of automatically turning off the power at the end of
the Burn-in of the tested power supply is convenient for unattended |
The computer automatically displays the quality of the tested power
supply product, and multiple windows in the window are convenient
for centralized
management, which saves operators and improves production
efficiency |
| The computer can store the Burn-in data report of the tested power
supply, the process parameters of the tested power supply are easy
to trace |
| RS232 to RS485 adopts photoelectric isolation converter to improve
communication reliability and prevent lightning damage to equipment |
| Each computer can monitor 18 devices at the same time, (each serial
port can connect to 63 slaves, and each computer supports up to 18
serial ports) |
| The power Burn-in monitoring software has a built-in help file,
which is convenient for solving operation questions immediately |
