Led Driver Testing Machine

Introduction
The Led Driver Testing Machine is used for testing the electrical parameter of each driver board after soldering. Through electrical parameter tester, testing the input voltage, current and power factors, and testing the output direct voltage, current and ripple; Realizing the fuction of reading, analysis, calculating and determining of the test results with the computer system.
1. Automatic selecting the relative load of driver board, and connecting with LED driver board. Read the test results from electrical parameter tester via the COM port or Ethernet network, and save them into the database.
2 .Three test types: short-circuit test, open-circuit test and electrical parameter test.
3. The parameters include:
Input test: current, voltage, power factor and power ;
Output test: direct current, voltage, power and ripple coefficient ;
Transfer efficiency of power panel.
4. After finshing test, via electrical load carrys out the function of automatic discharge to the driver board.
5. The processes of different driver boards can be pre-set into the computer. Automatic adjusting the variable-frequency power source and changing-over the electric relay, the control system will select the relative electronic load.
6. The system is consisted of below:
1). Industry Computer and I/O Controller
2). Electrical Parameter Tester, Variable-frequency Power Source, Electronic analog Load
3). Probe Box
4). Electrical Control Cabinet.
