RigolDP832 Programmable DC Voltage Regulator, 3 Channels, 195W, 30V/3A || 30V/3A, 5V/3A, Resolution 10mV/10mA, Constant Current Source, Constant Voltage Source

best psu I ever owned

Overall a good product with a quality feel to the case and controls. Works in spec with very good precision on output voltages and set currents. It is accurate enough to test the accuracy of cheap multi-meter's. It is a shame that the graphical display mode is a bit slow to update/respond. The updates take about 500 milliseconds after the change. It makes the dial and graph display modes less useful. The fan is a bit loud (28dB measured at .5M). It is a shame they didn't fit a thermally controlled fan as the fan is whirring away even when only a few mA is being drawn. My GW Instek power supply doesn't make any noise until things start to warm up. Keys are generally OK and look good but are a victory of style over content both in location and key design. I would prefer a traditional number pad. The V,mV,A,mA keys have sloping top making them awkward to press as they slip sideways. On balance a great unit for the money though.

Seems very reliable.Its louder than my last supply and I don't really like the controls layout. I would have preferred an independent encoder for each channel. However it does perform well.

Funktioniert sehr gut, nicht das erste und sicher nicht das letzte Gerät von Rigol.

I initially balked at the price of this thing, but I needed a new bench supply so I pulled the trigger and held my breath. I was really afraid this was going to be some Chinese junk with pretty paint and a bunch of issues. Nope! Its a very well-designed piece of equipment. In fact, you’ll pry this out of my cold, deads hands. I LOVE this power supply.Its a linear supply. Its heavy. Feels very solid in the build quality. No rattles, missing screws, or fit/finish issues at all. But the proof is in the juice. The output is very tightly regulated and shows a ripple of (get this) 0.00011 volts. 110 microvolts. This while powering a 1 amp resistive load at 5 volts.There are upgrades for this machine. Google it for specs, but in short this supply can be enabled to track down to .001 increments in both volts and amps. Darned impressive.Its rare that I fall in love with something from China, but this box really has me grinning. Its worth the price and more. It is very well-behaved and makes for a smooth experience on the test bench. If you are looking for a decent value with upgrade potential, look no further than this unit.

Très bonne alimentation de laboratoire programmable. Une puissance confortable sans être exceptionnelle et une précision au rendez-vous. De très utiles fonctionnalités. L’electronique et la mécanique sont celles de la version 832A, beaucoup plus chère. Cette référence est upgradable directement sur le site de Rigol (options payantes). Un peu bruyant (ventilateur puissant) même au repos. Un remplacement du ventilateur par un ventilateur de PC haut de gamme peut la rendre totalement silencieuse. A faire une fois la période de garantie passée. Les défauts des premières versions sont un vieux souvenir et cette alimentation est un très bon produit pour les hobbistes comme pour les pros.

very good

Cette alimentation triple Rigol est de très belle fabrication. Elle dispose de 3 entrées chainables, et d’une quantité de reglages ( U, I, limite I,... ) et d’une régulation de stabilisation très dynamique
