T4P, i should declare "an interest" first - I've just bought a Maynuo M9712B! (300W, 500V 15A)
In looking at the Array equivalent, a few points.
The Maynuo specs quote almost an order of magnitude better basic accuracy (Maynuo
0.03%+0.05%FS Vs Array
4.00~35.99V?0.2%+30mV )
The Array generally resolves to three decimal places (1ma, 1mV) while the Maynuo stretches to four for voltage (0.1mV) and five for current (10uA!!), BUT that last current place is
most iffy - call it four decimal places (100uA)
The array does boast a lower minimum or short circuit resistance; this is a function on the lower voltage mosfets. (The 500V Maynuo can "only" go down to about 0.25 Ohm)
The 500V Maynuo can only handle 15A, Vs the 360V Array's 30A. What do you really
need?
The Maynuo battery test function is an eye-opener; especially if you use a lot of rechargeable cells, and they don't seem quite as efficacious as they once were. The battery test function quickly weeds out dieing cells, with poor mAhr figures
The Array comes with wings
Why, I wonder? The Maynuo sports a front rubber bumper.
The Maynuo number pad is upside down (GRRR), but the Array number pad is even WORSE! Does this matter? Well, I find it slows down your direct input typing speed a lot, yes. To see how number pads SHOULD be laid out, look at an Array 3720 series (but don't look a the price - ouch)
The Maynuo sticks out about 120mm further (deeper) than the Array. How deep is your test bench?
The Array boasts FOUR fans to Maynuo's two. I suppose it depends on how big a fan fan you are. (Maynuo seems to manage fine with its internal pair)
The Maynuo includes a V-set function (Think: 300W Zener Diode!) while the Array appears not to offer this.
The Maynuo allows you to set a number of set points (i.e currents) and then switch or slew between them, so that you can observe how your power supply performs under transient load situations. I cannot see that the Array offers this. I am interested in transient performance, but your applications may not need this.
The Maynuo is about 50% more expensive than the Array
So I think that the Maynuo is " mostly winning" here, but it depends on your budget and whether you feel you actually need these extra features.
