    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

    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 :)

    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

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

    Second purchase, this time worked perfectly out of the box. Highly recommend this item only issue would be to say pitty when deactivating output with the ok button it doesn't turn off completely instead of just defaulting to 11.1 volts minimal. Simply put a master switch to input for total isolation (if required), no problem. Nice features: Fan, starts at first activation which is great to let you know its working. The led display is bright and easily read and the automatic and manual parameter
