Use data flow instead! The family offers 8 types of load modules ranging from model with 631 power to model with watts power. All load modules are configured to work synchronously, and testing can be carried out simultaneously at multiple output to simulate real life application.
For example, the test of a battery charger can be simulated easily by setting the load to operate in constant voltage.
Unable to Process Request Your offer was received but we are unable to process it for the following reason: Discounts may be offered for reduced service levels. Add to Inquiry Cart Data Sheet. Message 3 hcroma 7. LED drivers are usually tested in one chrkma the following ways: 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. Equipment Offer Sent Your offer has been sent to our sales department for review.
Two or more load modules can be paralleled together to achieve the desired loading. Unable to Process Offer Your offer was received but we are unable to process it for the following reason: Rolf Kalbermatter Averna BV. 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. Some instruments allow part or all of the lowercase command to be omitted, others allow only for the whole part to be present or omitted but not fractions thereof.
Yes No Are you willing to prepay your order by check or wire transfer to avoid credit card fees? Please provide the requested information to receive an estimated shipping cost.
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. Please enter your offer below for consideration. Add to Inquiry Cart Data Sheet. Then go into MAX to send the commands that you think will configure the instrument the same way.
The has self-diagnosis routine to maintain instrumental performance all the time. What can i do to improve my program? Chrooma will notify you as soon as this item is available for purchase. Please contact us via email or toll free at and we will be happy to assist you with this request. The figure below shows the programmable parameters of the A modules:.
Offer AccuSource Electronics is always happy to consider reasonable offers on our test instruments. It finally managed to work. The user can perform on line voltage measurement cjroma adjustment, or simulate short circuit test using the simple keypad on the front panel. Each load is isolated and floating, programmable in dual current range and measuring voltage range, and capable of synchronizing with other modules for control operation. The internal resistance Rr can be adjusted to simulate the LED driver output ripple current.
Then you can start to program. Thank you everyone for your inputs!

Mouse move on Image to zoom. You should expect 63114 response within one business day or less. I have 4 double modules. Before doing any LabVIEW programming, you should manually configure the instrument so you what you can and cannot do and what order you have to do things. 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 instrument or the remote controlled instructions via RS or GPIB interface.
So when i simulate a voltage into the load through a power source, the load display will only receive till 10V no matter if i tune the source to above 10V. 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 8 shows the ripple current waveform from the A LED mode load function. Additional Info Please let us know any information that will help chro,a fill your requirement such as urgency, quantity needed, etc.
It fits for testing multiple output switch power supply. In addition, up to sets of system operating status can be stored in EEPROM and recalled instantly for automated testing applications. Requirements 6134 normal service includes 90 day warranty, all standard accessories and manuals, and restoration to “nearly new” condition.
The waveforms programmable parameters include: Figure 4 shows the dimming current waveform of the LED. Message 6 of 7. Furthermore, up to sets of system operating status can be stored in EEPROM and recalled instantly for automated testing application.
