I am happy with the units, all working, despite the small chances, based on the "law of total probability", they arrived without damage, the quality of the assembly was not good in 2 units, 1 with the IC this diagonal in relation to the plate and 1 unit with part of the transformer missing, the solder is not bad, but it has no shine, this is not good. Thanks to the review by @samtree, very correct as to the need for a good LC filter and the use of a small fan to cool the unit, the resistor 100 ohms load at the output of 36v, it heats up a lot, even with the unit just turned on, the voltage is constant without load or with varying loads, in the aneng and hikari multimeters the voltage remained stable, the voltage variation seen in the photos is a problem of the voltmeter / ammeter, it erroneously shows an increase in voltage proportional to the increase in load. I don't know if it's the lack of a good LC filter at the 36v output, a common problem or just this voltmeter / ammeter.      #      Estou feliz com as unidades, todas funcionando, apesar das pequenas chances, baseado na "lei da probabilidade total", chegaram sem danos, a qualidade da montagem não foi boa em 2 unidades, 1 com o IC esta diagonal em relação a placa e 1 unidade com parte do transformador faltando, a solda não está ruim, mas não tem brilho, isso não é bom, agradeço ao review de @samtree, muito correto quanto a necessidade de um bom filtro LC e ao uso de pequeno ventilador para resfriar, o resitor 100 ohms de carga na saída dos 36v, esquenta muito, mesmo com a unidade apenas ligada, a tensão é constante sem carga ou com cargas variadas, nos multimetros aneng e hikari a tensão permaneceu estável, a variação das voltagens vista nas fotos é problema do voltimetro / amperimetro, ele mostra erradamente aumento da tensão proporcional ao aumento da carga. Não sei se é a falta de um bom filtro LC na saída de 36v, um problema comum ou apenas deste voltimetro / amperimetro.

Good power packs. It's not the first time. Used in a lot of crafts. 6 amps keep stable, but additional cooling is desirable. Without additional cooling 4 amperes keep on hurrah.

Хорошие блоки питания. Беру уже не первый раз. Использовал во многих поделках. 6 ампер держат стабильно, но желательно дополнительное охлаждение. Без дополнительного охлаждения 4 ампера держат на ура.

Izdelek prispel nepoškodovan. Embalaža je brez vsake sledi poškodb, tako je tudi izdelek nepoškodovan. Deluje izvrstno, tudi napetost je stabilna tudi, ko ga obremeniš. Izdelek se tudi po daljši obremenitvi ne greje pretirano.

It's giving off more power than the description says. It is described as 180W 5A, but in fact 320W 7.4 A comes off it at 36.4V. The price was much cheaper when I bought it, it was still for £2745.

Nagyobb teljesítményt ad le mint a leírás szerint. Leírásba 180W 5A szerepel, de valójában 320W 7,4 A jön le róla 36,4V-on. Ára jóval olcsóbb volt mikor megvettem, akkor még 2745Ft-ért adták.

Powerful current transformer, easy to install, requires a protective housing.

VISUAL INSPECTION : Quality of construction very good, no loose components, no bad solder joints. PERFORMANCE : It worked just out of the box. I left it without load for about 15 minutes and then I coupled three 12 Volts 50 Watts bulbs connected in series. Output 4.2 Amps (150 W). No smoke, no smell, no noise at all, output voltage extremely stable at 35.77 Volts (with no load) and 35.7 Volts (with 4.2 Amps load). So far so very good. Then I tested it more thoroughly with the same setup at 4.2 Amps (no smaller loads). My findings A. Voltage : Extremely stable. B. Cooling : Poor. As other reviewers have said, it can get really hot. After 10 minute at 4.2 amps, the temperature of the output heatsink reached 52 degrees Celsius and was going up (photo 1). Transformer and input heatsink were also too hot, output capacitors also felt hot. I installed above it a 8x8 cm, 24 Volts, 60 mA fan, and now it is really cold – after hours still 31 degrees Celsius. Perfect C. Output ripple (with 20 MHz filter set to ON): Not acceptable. At 4.2 Amps, it is about 850 mVp-p (photo 2), consisting mainly of a sinewave (630 mVp-p, photo 3) and on top of it are added the spikes ( 210 to 250 mVp-p - photo 4) due to the switching frequency. Reason: inadequate output capacitance. By simply adding a 4700 uF capacitor on the output (you can connect it directly to the spare positions on the output connector), the ripple goes down to about 350 mVp-p (photo 5). The quasi-sine wave is now much smaller (ca 50 mVp-p – photo 6), while the spikes remain the same. If you want, you can add on the output an additional LC filter like I did (13,5 mH inductor from the junkbox + 1000 uF capacitor), and go down to less than 160 mVp-p overall ripple (photo 7) because spikes are now 130 mVp-p or less (photo 8). Not bad. Conclusion : Add a fan and a 4700 uF output capacitor, and you have a decent general purpose 36 Volts Power Supply, with enough output current and for a very low price.
