Get rid of the stacked sequence structure – it makes it very difficult to see what is happening. It fits for testing multiple output switch power supply. That is where i derived it from.

The A series offers 8 different modules with power ratings from watts to 1, watts, current ratings from 0.
Message 6 of 7. The user interfaces include an ergonomically designed user friendly keypad on the front panel and the following computer interfaces: I had a look at your VI. The steps i 63114 to do: Dynamic Loading and Control The A loads offer high speed, programmable dynamic load simulation and control capability. Discounts may be offered for reduced service levels.
Figure 7 shows the ripple current waveform from a LED load. Real time measurement of voltage and current are integrated into each Chfoma load module using a bit precision measurement circuit. Then you can start to program.
Error Sending Request We are very sorry but an error on the server is preventing your request from being processed. The system is configured by plugging the user selectable load modules into the system mainframe. LED drivers are usually tested in one of the following ways: I have tried to fetch the voltage and current by sending: The has self-diagnosis routine to maintain instrumental performance all the time. Real time measurement of voltage, current, is integrated into each load module using a bit precision measurement circuit.
Then go into MAX to send the commands that you think will configure the instrument the same way. Message 7 of 7.
Message 3 of 7. Contact Info Please let us know how we can contact you. As a constant current source, the LED driver has an output voltage range with a constant output current. Thank you for allowing us the opportunity to assist with your test equipment needs.
Yes No Are you willing to prepay your order by check or wire transfer to avoid credit card fees? Because all that is chromaa in the labVIEW program i have written is already all the things i dhroma are feasible when reading the manual. The loads can be operated in constant current, constant voltage, constant 614 and constant resistance and may be placed in parallel for increased current and power.
When using a resistor as loading, the V-I curve of the resistor is not able to simulate the V-I curve of the LED as shown in blue on figure 1. Message 5 of 7.
Chroma 6314 Programmable DC Electronic loads
The A design also has increased bandwidth to allow for PWM dimming testing. Be aware though that sometimes the quality of the drivers might not be that great – but at least it’s a starting point. The A series has a self-diagnosis routines to maintain instrument performance.
Additionally, the A series offers an optional remote controller for automated production lines. Please let us know which of these you would be willing to consider for the price discount.
It finally managed to work. Figure 9 shows the current waveform from a resistive load. Its just that cbroma been using the wrong commands from 634 manual so my electronic load wouldnt accept it. These are the commands given in the manual book. Choma makes it inconvenient for mass production testing. The family offers 8 types of load modules ranging from model with watts power to model with watts power.
Thank you everyone for your inputs! Furthermore, up to sets of system operating status can be stored in EEPROM and recalled instantly for automated testing application. Versatile System Configuration Chroma Model Programmable Electronic Load integrates microprocessing capability into each load module and mainframe as the system operates in parallel processing mode to optimize the speed and control among multiple load modules.
Message 1 of 7. The waveforms programmable parameters include: Model and are designed to operate up to V in high voltage testing application.
