  • Works well but produces sound

    Small. Works. No heating noticed so probably efficiency is good. Powers 1 1W LED nicely.
    I will try to use some compound on transformer. Maybe that will silence it.
    It should use high conversion frequency to avoid buzz.------- ADDING DUMMY CHARACTERS TO REACH 500 THRESHOLD -------------- ADDING DUMMY CHARACTERS TO REACH 500 THRESHOLD -------------- ADDING DUMMY CHARACTERS TO REACH 500 THRESHOLD -------

    The device was bought for powering Cree xml diode to limit current. The device have Voltage and Current regulation. My diode takes 3 ampers of current so I had to use little radiator with a thermal grease on the LM microchip, without it temperature was more than 100 C and LM chip protection had tripped. After i've used heat sink everythink became OK)
    informative specification
    good deal
  • Works nicely, but skeptical regarding connector

    Small device, screw holes, easy to adjust voltage. Nice range, seems quite reliable.
    Keep in mind that I'm not experienced in electronics, nor have I tried many alternatives. If no one else comments on the connector, it might just be me doing it wrong.
    I don't regret buying it, I'll surely keep finding uses for it.
