This is a very good power supply, well worth the money. And the service from Telonic was outstanding, as usual. Highly recommended.

I’ve been using this for a number of months now. I thought maybe it would be overkill for my first power supply has a hobbyist but I frequently use output 1 and 2 together and have found myself using output 3 to power microcontrollers from time to time so the choice of 3 outputs was definitely a good one.
It’s super reliable and so awesome to be able to just start the thing up and demand multiple exact voltages and current limits at once for either quick testing or multi-day development of projects. It’s especially helpful in the early stages of product development when you haven’t added/decided on voltage regulation for the difference elements of your projects yet (e.g. one voltage for your microcontroller and another for a higher voltage element such as a servo motor).
Also being able to limit the current on outputs 1 and 2 is super helpful where you want to test something quick but don’t want to add resistors.
I’m no expert but I love this machine and will probably always buy Siglent and specifically from Telonic who were awesome.

I am an amateur radio and electronics enthusiast, who likes building RF circuits. I bought The Siglent SPD3303X-E for use on my workbench, replacing a much cheaper PSU which I found to be electrically noisy and difficult to set precisely.
I am absolutely delighted with my new power supply. It cost a little more than an amateur would normally spend on such a device but it is such a joy to use, being easy to set and the display being easy to read. It is not my first piece of test equipment bought from Telonic and it won’t be my last!
I am most impressed with it and I can highly recommend it.

Needed to develop and test a high-gain pre-amp and power amp combination to drive a hearing aid induction loop system for a relative, my previous (Chinese switching) PSU was quite noisy with switching spikes and ripple – so I bit the bullet and bought a Siglent SPD3303X-E.
.
Am absolutely delighted with it, superb control of voltage and current (the current limiter works well -don’t ask) and the noise is negligible (my Siglent ‘scope can barely see it).
.
Am impressed and very pleased, although more than I wanted to pay, it seems you do get what you pay for – highly recommended.
