    It was fault product. Output voltage is 32V at 0A, but supply current only 1.6A, output voltage became down to 24V. Open the case then I found two resistor (330Ω5W). Another one product(OK product) have three resistor (330Ω5W). I put on resistor, but I cannot fix. Finally, I found fault soldering, then I resoldering that. then I could fix it.

    I want to thank the staff who attended me very well and helpful, as the source is excellent and with quality you are to be congratulated on the product and the delivery was today and it went all right, I want to buy more of you, give 10 to zero on the competitor, Much better price speed and transparency in what they sell. I tested the source and it's ok.

    source with excellent value for money. Very well packaged. After the purchase, it took 46 days to be delivered: 11 days until the post, 5 days for shipment to Brazil, 21 days for customs supervision and 9 days for delivery by the Post Office. The order was charged by the Brazilian customs, but the full value was quickly redeemed by Banggood as I paid for the tariff insurance.

    Just tested them, max 32V, with a 4 ohm dummyload, Current 7.75A, 248W. Above 15V (4 ohm load) the EMC increases. (Some radio interference on a FM radio, app. 1 meter away) This is not unusual, not a real problem. I like and recommend them.

    Malý a výkonný. Skvělý poměr cena výkon a doručení z ČR, takže za dva dny doma. Maličko pomalejší reakce při regulaci a při aktivaci proudového omezení - při zkratu proud překminte velmi vysoko než se ustálí. Na domácí bastlení je to ale velmi šikovný zdroj.

    Package arrived in excellent condition and in expected time frame. Power supply was tested initially with dummy loads to check promised output voltage, output current and current limiting function. Basic delivery seems to be OK, but it cannot be used with sensitive electronic projects due to high output voltage noise. This could be improved with adding some low pass filter on FET gate drivers.

    This item came with hole in box but lucky unit not damaged. The casing badly assembled as can be seen from photos. Rubber feet uneven causing power supply box to stand rocking. On inspection inside found unit fairly well assembled but saw one of the wire wound resistors had broken loose . Bad support to front panel with only one side mounted. An extra support bracket is required here and the mounting holes are provided. After fixing power supply it preforms satisfactory and when compared to a lab supply only produced a small error with that indicated. Overall a good buy but assembly leaves much room for improvement.
