Hi everyone, I bought a new power supply from amazon, the brand is Matrix MPS 3005H.
Specifications.
-Two regulated power supply of 30V-5A, maximum 31V-5.1A
-Single fixed power supply of 5V-3A.
-Parallel, series and independent modes supported.
Highlights.
-Encoder type knobs, this feature is incredible because lock the value, you need push and turn knob for change value for current or voltage.
-OVP and OCP settings, this part I like it, because in OCP mode is very useful for me, fix a current value if limit is overpased, output turn off.
-Output botton independent for each power supply except fixed power supply.
-Start with programed modes, you can select if you want the power supply turn on with outputs on or off, turn off beep, or fix limits for voltage and current.
-Toroidal type tranformer.
-Low noise.
-Comes with three 4 mm plug alligator cables and printed user manual.
I think this power supply it has good quality for price range, I paid around 200 USD for it.
Only bad thing with this power supply is the fan noise, fan is activated automatically by temperature.
I hope your comments.
