    32 days from CHINA to ROMANIA by EU Priority Line. Package arrived with slightly bent side cover, but function is awesome. Tested without load, voltage indicator is very precise. Range is from 0V to 50V dc, when used at 230Vac input. Small load did not decrease voltage from set-point. Will be a much improvement a multi-turn potentiometer for voltage adjustment. I will install for my own one.

    Hi! I have got this product by rather fast shipping! BUT! It arrived in original good condition, but local final deliverer Post Office (Hungarian Post) has RUINED IT BY SUBMERS IT IN IN WATER IN THEIR STORAGE and an ADDITIONAL MECHANICAL DEFORMATION! Just now I claimed for refund from them because the Hungarian Post Office is responsible for this damage.... From China it arrived without any problem, but at the final 1,5 km died... As I schecked it, it should be a fine equipment for me, but just now I can use it as a table-decoration. I WILL BUY AN ANOTHER ONE WHEN I GET BACK MY MONEY from Hungarian Post. I am sorry for that I cannot write a real review. Later about the new one! BangGood has made a good job, it is NOT BG's or China Post's fault!

    I ordered 2 units for unsing them as a pre voltage regulator for my Hiland linear regulators and for my Ruidenfìg switching regulators. Both units output voltages - without any load connected - are close to 50Vdc at max value. The mini voltmeter inside the power suppliy unit is quite precise compared with the readings on an esternal multimeter. before connecting the mains voltage check the lateral voltage selector -230 or 120 Vac - . The spare potentiometer is useful if you wish to put an esternal voltage control. I did't yet had the opportunity to check my units with a load, but I hope that they will operate as promised. My only remark concern the packaging that it is not enough strong and one of the received power supply has the aluminium box that was bent; luckily it was easy to solve with a plier. Ho ordinato 2 unità per inviarle come regolatore di pre-tensione per i miei regolatori lineari Hiland e per i miei regolatori di commutazione Ruidenfìg. Entrambe le tensioni di uscita delle unità - senza alcun carico collegato - sono vicine a 50Vdc al valore massimo. Il mini voltmetro all'interno dell'unità power supply è abbastanza preciso rispetto alle letture su un multimetro esterno. prima di collegare la tensione di rete controllare il selettore di tensione laterale -230 o 120 Vac -. Il potenziometro di ricambio è utile se si desidera mettere un controllo tensione esterna. Non ho ancora avuto l'opportunità di controllare le mie unità con un carico, ma spero che funzionino come promesso. La mia sola osservazione riguarda l'imballaggio che non è abbastanza forte e una delle alimentazioni ricevute ha la scatola di alluminio che è stata piegata; per fortuna era facile da risolvere con una pinza.

    Für kleines Geld ein Supergerät von 0.0V bis knapp 50Volt. Wobei die eingebaute Spannungsanzeige relativ genau ist. For small money a super device from 0.0V to almost 50Volt. The built-in voltage display is relatively accurate.

    Buon alimentatore da testare sotto carico. Arrivato con alcune parti del case lato morsettiera piegati (deformati) dato l'imballaggio non è adeguato. In generale l'alimentatore si presenta bene, ha lo scambio 110-220V AC e la ventola per la dissipazione del calore che si accende sotto carico. Molto utile il voltmetro integrato nel case. Valore aggiunto un set di capicorda per il collegamento ai morsetti e un potenziometro aggiuntivo già cablato con connettore.

    The case of the PSU is made of aluminium, and as such was bent near the terminals on arrival. the unit works well and seems to deliver a nice smooth output. The in built volt meter is fairly accurate to within 0.3 volt. Need to be careful when using the mounting holes in the base of the PSU as being aluminium the threads strip easily. the circuit board flexes a fair bit when tightening the wire terminals. overall seems to be ok if handled with care.
