    Non so se funziona, perché è arrivato danneggiato. Sembra ben realizzato. Se funziona il rapporto qualità/prezzo e e l'aspetto meritano 5 stelle Lo riparo e poi faccio la recensione. Unico articolo danneggiato in tutta la confezione.

    Very interesting miniature and multi-voltage switching power supply for testing vacuum tube assemblies, where the voltages are greater than 250V under a few miliamperes or more up to 500W . The heat sink is necessary for high current output, but be careful with the isolation of the transistors subjected to very high potential differences and close to 350 to 380V. This module is to be isolated +++ to avoid any electrical risk. Beware of high frequency electromagnetic noise to be energetically filtered out.

    Não o testei ainda, mas confiando na Bangood sei que está tudo ok.

    I bought this product in to built small ups's. I wired the board up and managed to energize a heater and a globe but thats it. The wave form is so far from a sine wave that none of my ammeters actually picked it up. When I connected my desktop, which needs about 150W, the board went up in smoke. Please stay away from this product.

    The package came in three weeks, the goods were broken off a little plastic... Thank you very much for the product...!!!

    O conversor funciona corretamente. Não inseri cargas em alto valor pois o módulo não possui trocador de calor nos MOSFETs. O único inconveniente é em relação a não vir com uma chave ou mesmo um jumper para habilitar o PWM. Demorei até analisar o módulo e enxergar que precisava ser habilitado. Outro inconveniente está em não possuir o trocador de calor já de fabrica. No mais, recomendo o módulo.
