LED power supply load aging

One. The main function

1. The whole car using RS485 communication computer type electronic load module,

2. Computers can be programmable load size according to the demand from;

3. The computer real monitoring products tested output voltage and current value;

4. Each load with the LED indicator is on load condition, automatic judge products tested and computer display, intuitive and convenient;

5. The aging time and ON/OFF setting program, automatic timing closure function;

6. Computers can store power supply under test aging data and set to generate analysis report;

7. Every computer can monitor 8 sets of equipment, at the same time (each serial port can connect from machine 64 units, each computer maximum 8 serial port).

Two: the main characteristics

1. The main power devices are imported by the United States, Japan, long life and high reliability.

2. USES the German import IC main control chip, highly intelligent, reasonable design, reliable operation;

3. Digitally stepless setting load current value;

4. The function of load current soft start, the load process will have any impact to the products tested;

5. Load operation process can be unattended for a long time;

6. Optional configuration 485 / RS232 communication interface, can the remote real-time monitoring and composition of multi-motor control platform;

7. Optional multimachine parallel function, meet the needs of high-power multiple sets of test;

8. Temperature control fan stop driving, reduce the noise and energy consumption and prolong the service life;

9. The master modularization, the most simple and convenient operating interface;

10. High brightness LED double screen set of voltage and current value;

11. Constant current and constant voltage double work mode;

12. Had a temperature/high reliability polarity reverse connect protection function;

13. Single LED monitoring indication product output voltage and current is in line with the set value;

14. Trouble-free time interval (MTBF) of up to 87000 hours.

15. The load module, automatic monitoring product voltage current being measured.

Load module

3. The electronic load main functions:

1. High speed digital MCU as the main control chip;

2. Adopt RS485 international standard communication protocol;

3. The main components are imported materials;

4. Each channel can be set in a separate load parameters;

5. Perfect protecting OPP/OTP function;

6. Loading and back to read data quickly;

7. Provide protocol code user can be secondary development;

8. Independent dc power supply isolation;

9. Communication photoelectric isolation;

10. The multichannel parallel use;

11. Reliability MTBF in more than 80000 h;

12. The ship to air temperature control of aluminum air cooling heat dissipation;

13. Start self-check function;

14. The solid type quick connectors;

15. Modular easy installation is convenient;

16. More powerful online compatibility;

17. The available computers and touch screen monitor;

4. Monitoring software main functions:

1. The computer monitoring system for aging of power supply products for each parameter set management

1.1 aging can be set according to the product specifications, such as products tested voltage and current setting, aging time setting, etc.;

1.2 pre-set aging program can be stored in the computer, in the subsequent the types of products needed for aging used to be obtained;

1.3 need to temporary aging models can not directly stored on-site set up;

1.4 512 computer can monitor each module.

2. The computer real-time monitoring the aging state for each product

2.1 each product after entering aging, numbering system will be according to their location monitoring;

2.2 monitoring may at any time for each product to be obtained aging conditions, such as the product of the voltage being measured, the current value;

3. Bad alarm function:

3.1 in the process of aging products tested when the fault occurs (such as voltage beyond standard), monitoring and control system for display in the corresponding position will be used on color changing alarm prompt, till they get rid of the artificial or reset;

3.2 the computer system will automatically record and save the real-time testing data;

4. Data statistics function:

4.1 automatic generation of test reports, according to a preservation, obtain access to convenient;

4.2 voltage test report;

4.3 the temperature control curve;

4.4 quality curve;

4.5 SPC, CPK can choose.
