    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.

    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.
