Modular Load Design The Chroma and electronic load mainframes accept the user-installable series load modules for easy system configuration and fit 19″ instrument rack.

Figure 9 and 10 current waveform differs significantly from that of LED loading, especially the voltage and current overshoot, which may cause the LED driver to go into protection.

I have tried to fetch the voltage and current by sending: We hope to earn your business. We would also greatly appreciate it if you could provide us with this error code: What can i do to improve my program? The user can perform on line voltage measurement and adjustment, or simulate short circuit test using the simple keypad on the front panel. I had a look at your VI. The figure below shows the programmable parameters of the A modules: That is where i derived it from.

Figure 7 shows the ripple current waveform from a LED load.

Additionally, the offers an optional remote controller for automated production line. The A series will automatically detect the OCP point, making it an ideal solution for design verification as well as production line testing.

Get rid of the stacked sequence structure – it makes it very difficult to cnroma what is happening.

Dynamic Loading and Control The A loads offer cchroma speed, programmable dynamic load simulation and control capability. Message 5 of 7. Model and are designed to operate up to V in high voltage testing application. The system is configured by plugging the user selectable load modules into the system mainframe, and operated using the keypad on the front panel of the chrkma or the remote controlled instructions via RS or GPIB interface.


The loads can be operated in constant current, constant voltage, constant power and constant resistance and may be placed in parallel for increased current and power. The electronic load family can simulate a wide range of dynamic loading applications. Error Sending Request Chrmoa are very sorry but an error on the server is preventing your request from being processed.

Please enter your offer below for consideration. Discounts may be offered for reduced service levels.

Or are there any specific function i can write to control the load? Chrmoa AccuSource Electronics is always happy to consider reasonable offers on our test instruments.

The user can perform on line voltage measurements and adjustments or simulate short circuit test using the user friendly keypad on the front panel. Thank you everyone for your inputs!

The holds four load modules at most to offer 8-channel W input load with standard front-panel inputs. Yes No Are you willing to prepay your order by check or wire transfer to avoid credit card fees? The user chrkma include an ergonomically designed user cnroma keypad on the front panel and the following computer interfaces: If you go down the route of writing your own driver then you’ll need to be very careful about reading the device documentation to ensure you send the correct commands to the device e.

Figure 5 shows the dimming current waveform when using A as a load.

Figure 8 chrom the ripple current waveform from the A LED mode load function. The load can be operated in constant current, constant voltage, and constant resistance. 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.

Please let us know which of these you would be willing to consider for the price discount. The steps i have to do: Real time measurement of voltage, current, is integrated into each load module using a bit precision measurement circuit. Real time measurement of voltage and current are integrated into each A load module using a bit precision measurement circuit. Additionally, the A series offers an optional remote controller for automated production lines.


The has self-diagnosis routine chrmoa maintain instrumental performance all the time. From figures 2 and 3, the start up voltage and current of the LED driver is very similar. The A series has a self-diagnosis routines to maintain instrument performance. I am currently using VISA attached but my program doesnt control the load. Model sinks a maximum current of A, and is the most costeffective in high power testing application.

Because all that is stated in the labVIEW program i have written is already all the things i think are feasible when reading the manual. Parallel Control The A provides parallel control, which enables high power testing when a single module cannot meet the requirement of high power applications. You should expect a response within one business day or less. Standard accessories supplied by the original manufacturer No manuals or accessories required Other specify Will you accept an 634 with minor cosmetic and physical flaws if it operates properly?

LED drivers are usually tested in one of the following ways: Any comment or help is appreciated especially if you have used this dummy load before. It finally managed to work. Mouse move on Image to zoom. Also – even if you just use raw serial commands – you never configure the serial port to have the right parameters e.
