Message 3 of 7. Message 1 of 7. Any comment or help is appreciated especially if you have used this dummy load before. Actually this syntax is pretty common for IEE Figure 2 shows the current waveform from a LED load.

Chroma 6314 DC Electronic Load Mainframe With Manual O1

Message 6 of 7. This makes it inconvenient for mass production testing. 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. 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 system is configured by plugging the user selectable load modules into the system mainframe. The user can perform on line voltage measurement and adjustment, or simulate short circuit test using the simple keypad on the front panel.

Standard accessories supplied by the original manufacturer No manuals or accessories required Other specify Will you accept an instrument with minor cosmetic and physical flaws if it operates properly?

Because all that is stated in the labVIEW program i have written is already all the things i crhoma are feasible when reading the manual. Get rid of the stacked sequence structure – it makes it very difficult to see what is happening.


I have tried to fetch the voltage and current by sending: The family offers 8 types of modular loads with power ranging from watts to wattscurrent from 0. It fits for testing multiple output switch power supply.

Chroma 6314

The built-in resistive load current sensing circuit is capable of measuring current with an accuracy of 0. The programmable slew rate makes the simulation of transient load change demanded by real life applications possible. 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.

Or are there any specific function i can write to control the load?

The load can be operated in constant current, constant voltage, and constant resistance. Please enter your offer below for consideration.

Its just that ive been using the wrong commands from the manual so my electronic load wouldnt accept it.

The internal resistance Rr can be adjusted to simulate the LED driver output ripple current. Contact Info Please let us know how we can contact you.

Unable to Process Offer Your offer was received but we are unable to process it for the following reason: Real time measurement of voltage, current, is integrated into each load module using a bit precision measurement circuit. 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.


These are the commands given in the manual book. Discounts may be offered for reduced service levels. Figure 5 shows the dimming current waveform when using A as a load. All load modules are configured to work synchronously, and testing can be carried out simultaneously at multiple output to simulate real life application.

Chroma – Programmable DC Electronic loads

The A series offers 8 different modules with power ratings from watts to 1, watts, current ratings from 0. The figure below shows the programmable parameters of the A modules:. 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.

Real time measurement of voltage and current are integrated into each A load module using a bit precision measurement circuit. The A series can simulate a wide range of dynamic loading applications. OCP Test By 6341 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.

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. Mouse move on Image to zoom. Message 2 of 7. 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.
