    El producto se ve muy bien. Envío rápido a Ciudad del Cabo, Sudáfrica. Aún no lo he probado.

    Havent tried it yet as i dont have anything to power it with yet but it looks good :) the most impressive part is that i ordered it on the 13th and it reached on the 25th, from china to sweden, so very fast shipping, atleast compared to my past experiences when ordering from china, definitely recommend seller :)

    This unit is the right choice for replacing the old B400W DC-DC power supply. It is able to increase the voltage to 120V and the output change is very quick (in the B400W the output voltage arise very slowly). the voltage measurement is precise and the output capacitor are rated 200V. if you need an updated version of a CC and CV DC-DC power supply for high voltage, this is the right solution. The operativity is very simple and the button panel and display are the same you find on the power supply from the same brand. good value for money, suggested. Questa unità è la scelta giusta per la sostituzione del vecchio alimentatore DC-DC B400W. È in grado di aumentare la tensione a 120 V e il cambio di uscita è molto rapido (nel B400W la tensione di uscita cambia molto lentamente). la misura della tensione è precisa e il condensatore di uscita ha una tensione nominale di 200V. se hai bisogno di una versione aggiornata di un alimentatore DC-DC con CC e CV per alta tensione, questa è la soluzione giusta. Il suo uso è molto semplice; il pannello tasti e il display sono gli stessi che si trovano sugli alimentatori della stessa marca. buon rapporto qualità-prezzo, suggerito.

    The output does not follow the preset voltage when the preset voltage is below the input voltage. In that case the current limiter (CC-Value) does not work and the output voltage is allmost equal to the input voltage. This means: 35 input voltage, preset value 12V. output = 0V. After pressing the OKbutton the voltage jumps not to 12 but to 35V (and my test lamp was burnt). This is clearly warned in the manual. What not is warned for is the absence of the current limiting function in that case. I tested the output till 120VDC and 150W output with 35VDC input

    It is suitable for drive dc motors.I am planing to try it to stepper motor drive.Thanks for 12 day fast shipping.

    ¡Funciona bien! ¡Puedo usar un cargador de AC/DC en mi camioneta en un sistema solar gracias a eso!
