content: Hi All,I just released a review for the new Miniware MDP-L1060 DC electronic load, I thought I would post it here for reference.

content: Have you tried having it dissipate 100W continuously yet?Maybethey can get away with 100W with this density, but I have a suspicion it might run pretty hot. Also small fans + high airflow seems like a recipe for loud acoustics.Slightly concerned about the metal casing on what is supposed to be a floating device when running from internal battery or through an isolated plug pack. Can I get a shock by holding it, when the device is connected to let's say a 20V voltage source but floated to few hundred volts relative to mains earth? Also what's the leakage current injected back into the DUT when running from a plug pack?I quite like the idea of their power supply, being able to take it with me, powered by a battery bank, and provide a clean adjustable voltage to DUTs in the field. Not sure what I would do with a portable load though.Also the lack of dynamic loading function is quite disappointing, meaning you can't test output transient response of power supplies.If it is cheap, then I guess it is worth having as a step up from the janky heatsink bolted to a PCB DC loads for hobby use. But if it is priced similar to their power supplies (judging by the amount of metal and stuff in there, probably more expensive than their power supply modules), I have no idea who it is really for.

content: I could certainly do a follow up video looking at questions people have asked about it.There is a dynamic testing function, I briefly showed it in one of the M01 screens, again I could look at this in a followup video if time allows.

content: The specs of this load are "just what I want" but I could not find any trace in the documentation about a programming interface.And by programming I mean some interface over USB to control it not a text file with dubious characters.So I ask, maybe I missed this somehow, is this thing program-able in like Python or C over USB ?No wireless please.

content: actually I have a set of this gear, a MDP-M01, the console; two P906s and an L1060.in general I quite like them as the whole set can put on to my tiny desk, I use them for low power DC-DC tunning and embedded system debugging, it's more than enough.with M01 you can do the dynamic test on the E-load, but the simple ones not the complex ones.I heared from their management team from some sources, they are developing PC app for this power supply system, and the UI of M01 would be totally different.for me I like this kind of product, as they are tiny, fine to the details.

content: Quote from: rteodor on May 11, 2024, 04:46:27 amI see, unfortunately this E-load is currently not supporting API like SCPI, so automation with other equipment or secondary developement is not viable. it currently supports ON/OFF durations control on the console, and lister file import but none of them is line-interactive, hoping the remote control will be available when the PC App is released.cheers,
