Key Features Regulatory Compliance: Figure 2 shows 631 current waveform from a LED load. LED drivers are usually tested in one of the following ways: 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. The A series has a self-diagnosis routines to maintain instrument performance. Get rid of the stacked sequence structure – it makes it very difficult to see what cnroma happening.
All load modules are configured to work synchronously, and testing can be carried out simultaneously at multiple output to simulate real life application.

Discounts may be offered for reduced service levels. It fits for testing multiple output switch power supply. The internal resistance Rr can be adjusted to simulate the LED driver output ripple current. Message 5 of 7. The user interfaces include an ergonomically designed user friendly keypad on the front panel and the following computer 634 The has self-diagnosis routine to maintain instrumental performance all the time.
The command line syntax crhoma those instruments is usually case insensitive and the uppercase part of the command is mandatory while the lower case part can be ommitted but doesn’t have to.
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. The A series offers 8 different modules with power ratings from watts to 1, watts, current ratings from 0. Message 6 of 7. Figure 5 shows the dimming current waveform when using A as a load. Also – even if you just use raw serial commands – you never configure the serial port to have the right parameters e.
I had a look at your VI. Unable to Process Offer Your offer was received but we are unable to process it for the following reason: OCP Test By simply choosing the channel and setting the OCP parameters start current, end current, step current and dwell time from the front panel, the A series provides a fast and easy OCP testing solution.
If my VISA Write and Read works fine when i want to fetch voltage and current, shouldnt i be able to control the machine by putting: Be aware though that sometimes the quality of the drivers might not be that great – but at least it’s a starting point. Additionally, the A series offers an optional remote controller for automated production lines.
Then you can start to program. 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 figure below shows the programmable parameters of the A modules:.

You should expect a response within one business day or less. Correct Issue Close Wizard.
This makes it inconvenient for mass production testing. The built-in resistive load current sensing circuit is capable of measuring current with an accuracy of 0. Message 1 of 7. From figures 2 and 3, the start up voltage and current of the LED driver is very similar.
Most Active Software Boards: Auto-suggest helps you quickly narrow down your search results by suggesting chromma matches as you type.
Chroma – Programmable DC Electronic loads
I have 4 double modules. The system is configured by plugging the user selectable load modules into the system mainframe. Furthermore, up to sets of system operating status can be stored in EEPROM and chdoma instantly for automated testing application.
Please contact us via cnroma or toll free at and we will be happy to assist you with this request. Dynamic Loading and Control The A loads offer high speed, programmable dynamic load simulation and control capability.
As a constant current source, the LED driver has an chrmoa voltage range with a constant output current. Thank you for allowing us the opportunity to assist with your test equipment needs.
Or are there any specific function i can write to control the load? The user can perform on line voltage measurements and adjustments or simulate short circuit test using the user friendly keypad on the front panel. Use data flow instead! The steps i have to do: In addition, up to sets of system operating status can be stored in EEPROM and recalled instantly for automated testing applications.
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. Model sinks a maximum current of A, and is the most costeffective in high power testing application.
Contact Info Please let us know how we can contact you. The family offers 8 types of load modules ranging from model with watts power to model with watts power. The load can be operated in constant current, constant voltage, and constant resistance. Its just that ive been using the wrong commands from the manual so my electronic load wouldnt accept it.
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. Message 2 of 7.
