    rigol DP832 – DL3021 and DS1104z plus
    i am a retired electronics engineer (radio & tv) and decided to replace some of my ageing equipment, the DL3021 dc load is great never had one of these before, the DS1104z DSO took a bit of getting used to but now would not be without. the DP832 power supply is great set it forget it beats my old forever driffting power supply hands down….
    all this new equipment does so much more, could rabbit on for a long time..fantastic.. i have two more pieces of equipment i require but will have to wait a little while for those, so thank you rigol/telonic for your great service… really chuffed thank you Alan.

    RIGOL DP832 Power Supply
    Very happy with my purchase and the good communication from Telonic.

  4. Pyers E

    Great little PSU
    Very happy with the Rigol DP832. Does exactly what it says on the tin, without fuss. Rigol/Teleonic were a great company to deal with and helped me out when I realised I’d initially ordered the wrong product! Highly recommended.

  5. Paul K

    Have been reviewing numerous power supplies of this type for some considerable time. I was very impressed with the fast delivery, tracking updates and the packaging. The product itself seems to be good quality, loads of features and is very nice to use. Downsides: non UK mains lead, and no power leads to get you going.

  6. Kevin M

    Rigol DP832 PSU
    Excellent service from Telonic Instruments. The power supply was ordered on Monday and we received the unit next day. The power supply is a very good unit. So all in all very happy to recommend this power supply from Telonic Instruments.

  7. Ian W

    Excellent seller
    I’m not about to review the product (Rigol DP832), there are plenty out there that are far better than anything I can do.
    What I will say is that Telonic Instruments are excellent. This is the third piece of Rigol kit I’ve ordered from them in as many weeks and like the previous, it arrived within a couple of days.

  8. Robbie L

    Superb power supply
    I was already very pleased with an oscilloscope I bought from this company last year. The DP832 is the same high standard of quality I expected. Yes it’s big and heavy and the fan is a bit loud but I expected that. The features are amazing. Great service, arrived next day.

  9. Paul E

    A Great little PSU
    Great PSU for the price. Took them a few goes to fix some design flaws with some of the internals but after a few years in the field these are a solid bit of kit now.

    Check http://www.eevblog.com/ and his youtube channel for reviews and updates on the flaws and fixes of this unit.

  10. SteveR

    Excellent power supply very quick delivery. Not my first piece of Rigol equipment was impressed with first piece and this helped with the decision to purchase this power supply

  11. Stephanie F

    Good value for money
    The DP832 is aesthetically pleasing in design as well as performing well.
    It is reassuringly weighty and does what it says on the box.
    Delivery from Rigol was swift and I will continue dealing with them.
    Happy customer 🙂

  12. Daraban I

    Rigol DP832 Linear DC Power Supply
    Just bought this power supply , it’s a good one , helps with all my applications , and the dual power line for +-15 volt combined with the 5 volt rail helps my application to get what is needed .
    It’s an expensive power supply for it’s capability , it does need some improvements , the fan it’s very noise and the shared ground GND between source 2 and source 3 seems that is not a proper ground , i do have a milivolts reading between those to points. I’ll hope to figure this out , i might open the power supply to rectify this issue .

  13. Mark P

    How good is this PSU
    Fantastic product. To be honest I can’t flaw any of its functionality but in my home lab, it’s just too deep.mi have a Rigol scope which is nice and shallow but this PSU is nearly 0.5m deep which makes it stick out on my bench a lot.

    Rigol DP832
    Very Nice Supply, with hi-res upgrade it has everything thing you need.

  15. Andres T

    Perfect Deal
    Great prices and next day delivery!

  16. MH

    DP832 PSU
    This is a great supply and makes a good replacement for my old Farnell. If I have any issues its the fan noise. Rigol could have used a lower noise fan. Otherwise I suspect very difficult to beat for the money. I will probably buy another Rigol piece of test equipment in the future.

  17. Stuart

    Quck delivery, latest firmware
    Very quick delivery, was programmed with the latest firmware and appears to have had gone through a good QA check by Telonic prior to shipping!

  18. Glenn A

    Cracking bit of kit!!
    I was in need of a reliable bench power supply with at least 2 if not 3 outputs and after a lot of research found the Rigol DP832 so decided to order one.

    The Rigol DP832 power supply came very well packed and arrived very fast after ordering. I did talk to the guys at Telonic Instruments before purchasing just to clear up a couple of points I needed to know and they couldn’t have been any more helpful thanks guys.

    If you are like me a home electronics hobbyist and engineer with a need for well built no nonsense easy to use bench power supply with 3 outputs you can’t go far wrong with this. It’s built very well and is packed with easy to use functions that take no time at all to get the hang of. The build quality far exceeds its price which is an absolute bargain for what you get.
    If you are looking for a top quality 3 output bench power supply then you have found it, its a great bit of kit you wont regret buying.
    Hope this helps you decide.

    Thank you very much!

    The DP832 Power supply is a dream to use every thing about it is straight forward you don’t need to read the manual.
    The quality is first class this is my second Rigol product I own and will be buying their multimeter next.

  22. Vinoth G

    Works great!
    Been using it for a while, the scope works great and the UI is very user friendly.
    Highly recommended for hobby use as well as for professional use.

    Telonic comment: Thanks for your kind review on the Rigol oscilloscope.

  23. Christian E

    Overall great experience
    The main reason I bought from Telonic was the lowest price I could find online. Opted to pay £10 extra for Standard delivery which was great. I wouldn’t have been home when this was to be delivered but I was able to pick it up at the courier that same day without having to wait for a failed delivery attempt.
    The only critique is that it didn’t have the latest 1.14 firmware version despite the advertised “firmware guarantee”, but I’m happy to upgrade this myself. Overall though I’m very pleased with the service.

  27. S H

    Superb build quality & great customer service
    Had a couple of queries about the product & order after it was placed so phoned up Rigol-UK and got some advice about potential future purchases as well.

    The DC Power Supply is extremely well constructed and appears to be pretty accurate when double checking it’s output via 2 multimeters.

    Will definitely be back in the not too distant future

    Delivery issue
    Was disappointed that the unit had to be recalled when on its way to me- delivered two days after that.
