    Pic not acurate, shows old style PCB/Kit

    Overall: 3.5 out of 5

    We use these at work in a switching box on a tester. We cycle them a lot and they do wear out after a few million cycles. Kit does not come with heat sink so you will need to buy it along with thermal compound. If you only need a little thermal compound Radio Shack sells a small tube...not the best quality but it works. Velleman has change/update the PCB to half the size and with a vertical main capacitor so its much taller now. I had to do some modifications/wiring to make it fit in our application including replacing the supplied pot with a remote panel mounted pot (we use a 5k 10 turn). The value of the pot has changed to 4.7K from 5.0K. Regulator gets really hot so provide ventilation or cooling fan.
