Programmable DC Electronic Load DL3000 Series

 

DL3000 is a cost-effective programmable DC electronic load with high performance. With a user-friendly interface and superb performance specifications, DL3000 series provides various interfaces for remote communication to meet your diversified test requirements. It can be widely used in various industries, such as automotive electronics, aerospace, and fuel cells.

Design Features

   

30kHz dynamic mode

30kHz dynamic mode

×

Transient test function enables the load to periodically switch between two set levels (Level A and Level B). It can be used to test the transient characteristics of the DUT. The highest frequency can be set to 30 kHz. Besides, in the guide interface, you can configure parameters in the parameter configuration list and view the configuration diagram at the left of the configuration list in the real-time manner.
 

Powerful list operation function

Powerful list operation function

×

You can generate complex sequences by editing the setting value for each step, the dwell time, and slew rate (the slew rate can only be edited in CC mode) to meet the complex test demands.

5 A/μs current rising speed

5 A/μs current rising speed

×

Current rising speed is defined as the speed of transition from one setting to another. You can set the actual transition time from one setting to another by changing the current rising speed. Adjustable current rising speed: 0.001 A/μs to 5 A/μs.




Powerful waveform display function

Powerful waveform display function

×

The electronic load provides the waveform display function and supports the following operations for the waveform, such as pausing the waveform, enlarging and narrowing the waveform, and capturing the waveform. Therefore, you can dynamically observe the trend of parameters changes.

 

Easy-to-use function of file storage and recalling

Easy-to-use function of file storage and recalling

×

The load allows you to save different types of files to the internal and external memories. You can recall and read them when necessary.

Sound OVP/OCP/OPP/OTP/Reverse Voltage Protection

When OVP/OCP/OPP/OTP/reverse voltage protection occurs, the load will immediately turn off the input automatically and stop sinking. Then, a prompt message is displayed.

Good Equipment

Although I have used all the modes, my needs are mostly CC and battery testing. I have used it load testing several power supplies mostly linear type and weeding out weak batteries from my rechargeable inventory. It does exactly what I want it to do. I have several pieces of Rigol equipment so I didn't think it was difficult to use. I am happy with my purchase.

I'm Happy

I have used this on 4 power supplies and did some battery testing and it does all that I want it to do. I would have liked a larger one, but couldn't handle the price. I have several pieces of Rigol equipment, so the operation seemed intuitive to me. My only complaint is I would like to see a printed users manual included, the quick start is a waste.

Good but hopefully will get better

Functionally the DL3000 works as intended. It does fulfill my needs but has some quirky user interface issues you need to be careful about. The most significant User Interface issues is easily seen when setting the current in the CC mode. When you enter a number that is not an integer (1.25 for example) the unit works as expected. However if you enter a number less than 1 (0.25 for example) you MUST enter the leading zero ("0.25") , If you enter ".25", the entry is interpreted as 25!! This is not wrong as such but is very dangerous . The front panel control includes a rotary knob but unfortunately this is not used effectively, For example in the CC Mode it increments the least significant digit which is 1mA. Increasing at such a low rate means you generally won't use the rotary control. you would expect that the rate of adjustment would increase if you turned the knob faster but that is not implemented in the current firmware. Very disappointing. The PC interface provided could be very useful. It works but is implemented very poorly. It has so many bugs and quirky interface issues that it is not practical to include them in the review. Looks like it was created by an intern over the weekend. Despite these problems the product is useful and a good addition to my test lab. I am hoping that firmware upgrades are on the way!

Good value but has its quirks and bugs too.

Functionally this unit works as advertised and is very good value for money. Unfortunately with the current version of firmware it has some significant flaws.

Panel layout is OK although it is odd that the primary functions (LOAD ON/OFF, TRANS, SHORT) are in the midst of a sea of buttons rather then being conveniently located near the output connectors.

The user interface has many issues, some of which can lead to operational problems. For example if you want to set the output current (in CC mode) to 0.5A you MUST enter the leading zero otherwise you will select 5A (the decimal point is ignored without the leading zero). This is not just a matter of inconvenience, it means you can accidentally enter a number if you don't press the first digit correctly.

The PC interface ULTRALOAD (Windows) is clearly a work in progress. It was rushed to market and poorly tested. There are too many issues to put into a short review. The RECORD window would be useful if you could set the vertical scale range. This is sort of set by the RANGE value, but it is buggy and has to be accessed from the CV menu to set voltage, and from CC for current regardless of what mode you are in. Also scaling for the current graph is actually incorrect. For example displaying a current of 4A (which should be full scale on the 4A range( indicates more like 3A). Talk about poor testing! If there was more space I would give a complete review and I would be happy to provide feedback directly to Rigol as fixing the many issues would produce a truly great product.

Having said all of that this is a useful device, and better still if Rigol addresses the many firmware/software issues soon.

Tequipment and Rigol factory Response: Thanks for the detailed feedback. RIGOL works hard to make improvements that make instruments easier to use for our customers. All of your firmware and software comments have actually already been identified. While we can't commit to when a new revision will become available, we do have plans to make some usability improvements in this new device. Feel free to contact us directly with other suggestions as how you use the instrument is important to us. I find the easiest way to utilize the record function on UltraLoad is to record the data to a file and then open it in Excel where the scaling can be optimized for analysis. The UltraLoad graph shows basic visualization, but easy scaling of that graph is something we would like to improve. I'm glad you are enjoying the instrument and please drop us an email directly at RIGOL so that we can let you know when a new version is available.

Rigol DL3021

The electronic load works fine. The problem I have is that the advertisement for this model actually has a picture for the DL3031 of higher model while the DL3021 is the same except that all the color in the images of the front face is actually represented as grey or white buttons. I just wanted an accurate image of what I was buying or some information indicating that the model I purchased had a different or B/W front face. This company sold me the product at a fair price but did not do their homework and propagated the false claim of their supplier. I would hope that this company is more than a drop shipper and knows/inspects what it sells so that the statements made in their text or images in their ad accurately reflects what is being sold.

Tequipment Response: Thank you for your feedback. The image we had is one we have for the product as a series. We will update the image. Please contact us and we will give you a 5% credit for the issue and feedback. Thanks.
