Review on ⚡️ Siglent SPD3303X-E Triple Output Power Supply: Maximizing Efficiency and Versatility by Charles Barney

Pros: Well thought out voltage and current functions, V/A/W main display is crisp and clear, serial and parallel functions are great, and the network interface is both well documented and fully comparative to the front panel controls. The "Lock" function is excellent. It can store up to five "scenes" in memory, so you can keep common settings close at hand. These are all good reasons to buy something like this, so the pros here, while shorter than the cons section below, are actually something to focus on if you want a good dual power supply. Double? Yes. This is truly a dual channel programmable power supply. This third channel. Check out the cons below. Cons: 1) A Windows computer is required to update the firmware. There should have been a slot you could put a memory card in to make it platform independent and given the price of the device I don't see a good excuse not to do so. A lot of people don't use Windows, and for very good reasons. Also, the device has a network interface and can be updated over the network if it is simply designed for it. A $20 IOT lightbulb can do this. There's no legitimate excuse for a $400 lab piece of equipment not having this capability. 2) The display brightness is not adjustable. There must be. It's VERY bright. 3) Graphics are extremely minimal; It is better to use the network interface and monitor the power status yourself. This allows you to gather stats, catch rare events, etc. 4) No built-in event trapping/firing: you can leave the device on, not be in the room when something happens, and without a hint of , and no details come back to Event when it scrolls past the (very minimal and short) chart display. There should be configurable alarm/trap options to mark/log events. Again, given the price of the device, there's no good excuse not to have one. 5) The third floor is handy, but not much better than a wall wart. For the third channel, there is no current tracking, current limit control, or indicators other than the off/on/overload LED. -E provides two decimal places for precision instead of three. I highly doubt that this will be of any practical use to the vast majority of users. --- So. I like the unit. The dual channel programmable power supply is an extremely useful tool if you are a designer or a maker. I'm happy with the price, but would have liked more features. Some of what's missing I'll create with a network interface, but not every piece of hardware is a programmer, so just because I can do it doesn't mean someone else can. So for me this is really a very good buy. For someone else, the caveats implied in the cons section above may be relevant. If not, then I would definitely recommend the device.
