The A series offers 8 different modules with power ratings from watts to 1, watts, current ratings from 0. Each model is designed with specific applications in mind. The figure below shows the programmable parameters of the A modules: Error Sending Request We are very sorry chrona an error on the server is preventing your request from being processed.

Discounts may be offered for reduced service levels.

Chroma 6314 Programmable DC Electronic loads

Mouse move on Image to zoom. Figure 5 shows the dimming current waveform when using A as a load. These are the commands given in the manual book.

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. Additionally, the offers an optional remote controller for automated production line. Correct Issue Close Wizard. The built-in resistive load current sensing circuit is capable of measuring current with an accuracy of 0.

The system is configured by plugging the user selectable load modules into the system mainframe. The A comes with RS as standard for remote control and automated testing applications. Message 4 of 7. Requirements Our normal service includes 90 day warranty, all standard accessories and manuals, and restoration to “nearly new” condition. Figure 7 shows the ripple current waveform from a LED load.


I have tried to fetch the voltage and current by sending: Figure 8 shows the ripple current waveform from the A LED mode load function.

The internal resistance Rr can be adjusted to simulate the LED driver output ripple current. 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.

Real time measurement of voltage, current, is integrated into each load module using a bit precision measurement circuit. From figures 2 and 3, the start up voltage and current of the LED driver is very similar. The load can be operated in constant current, constant voltage, and constant resistance.

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.

I purposely put chrooma cases so it would be easier for me. Unable to Process Request Your offer was received but we are unable to process it for the following reason: LED drivers are usually tested in one of the following ways:. All load modules are configured to work synchronously, and testing can be carried out simultaneously at multiple output to simulate real life application.

The user can perform on line voltage measurements and adjustments or simulate short circuit test using the user friendly keypad on the front panel. 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. Contact Info Please let us know how we can contact you.

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. As a constant current source, the LED driver has an output chroam range with a constant output current. Figure 3 shows the current waveform from A’s LED mode load function.


I am currently using VISA attached but my program doesnt control the load. Two or more load modules can be paralleled together to achieve the desired loading.

Chroma – Programmable DC Electronic loads

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. Model and are designed to operate up to V in high voltage testing application.

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: The has self-diagnosis 63144 to maintain instrumental performance all the time.

The family offers 8 types of load modules ranging from model fhroma watts power to model with watts power. Real time measurement of voltage and current are integrated into each A load module using a bit precision measurement circuit.

We will notify you as soon as this item is available for purchase. Figure 4 shows the dimming current waveform of the LED.

Most Active Software Boards: The A series can simulate a wide range of dynamic loading applications. The programmable slew rate makes the simulation of transient load change demanded by real life applications possible.
